Four Types of Steel

According to the American Iron & Steel Institute (AISI), steel can be categorized into four basic groups based on the chemical compositions:
1. Carbon steel
2. Alloy steel
3. Stainless steel
4. Tool steel

All steel is composed of iron and carbon. It is the amount of carbon, and the additional alloys, that determine the properties of each grade. There are many different grades of steel that encompass varied properties. These properties can be physical, chemical, and environmental. Let’s take a closer look!

Carbon steels contain trace amounts of alloying elements and account for 90% of total steel production. Carbon steels can be further categorized into three groups depending on their carbon content:

● Low carbon steels/mild steels contain up to 0.3% carbon
● Medium carbon steels contain 0.3-0.6% carbon
● High carbon steels contain more than 0.6% carbon

Alloy steels contain alloying elements (e.g. manganese, silicon, nickel, titanium, copper, chromium, and aluminum) in varying proportions in order to manipulate the steel’s properties, such as its hardenability, corrosion resistance, strength, formability, weldability, or ductility. Applications for alloy steels include pipelines, auto parts, transformers, power generators, and electric motors.

Stainless steels generally contain between 10-20% chromium as the main alloying element and are valued for high corrosion resistance. With over 11% chromium, stainless steel is about 200 times more resistant to corrosion than mild steel. These steels can be divided into three groups based on their crystalline structure:

Austenitic: Austenitic steels are non-magnetic and non-heat-treatable, and generally contain 18% chromium, 8% nickel, and less than 0.8% carbon. Austenitic steels form the largest portion of the global stainless steel market and are often used in food processing equipment, kitchen utensils, and piping.
Ferritic: Ferritic steels contain trace amounts of nickel, 12-17% chromium, less than 0.1% carbon, along with other alloying elements, such as molybdenum, aluminum, or titanium. These magnetic steels cannot be hardened by heat treatment but can be strengthened by cold working.

Martensitic: Martensitic steels contain 11-17% chromium, less than 0.4% nickel, and up to 1.2% carbon. These magnetic and heat-treatable steels are used in knives and cutting tools, as well as dental and surgical equipment.

Tool steels contain tungsten, molybdenum, cobalt, and vanadium in varying quantities to increase heat resistance and durability, making them ideal for cutting and drilling equipment.
Steel products can also be divided by their shapes and related applications:

Long/tubular products: These include bars and rods, rails, wires, angles, pipes, and shapes and sections. These products are commonly used in the automotive and construction sectors.

Flat products: These include plates, sheets, coils, and strips. These materials are mainly used in automotive parts, appliances, packaging, shipbuilding, and construction.

EDI – Value-Added Benefits in the Steel Industry

Patton Quinn2020-05-14T15:52:23+00:00May 14th, 2020|News Blog|

If your company takes part in supply chain processes, then you know how easy it is to lose control of the entire document flow and how important it is to have real-time access to reliable information regarding the delivery process. In traditional methods of business to business (b2b) communication, misunderstandings can often occur. Often, these misunderstandings are regarding collection and loading time, load capacity, product specificity, how the goods were packed and sent, and status of delivery. Manual entry data can result in incorrect documents, invoice totals can be erroneously entered, inaccurate invoice information can delay payment date, and delay receiving money to buy raw materials. Paper documents can become lost or filed in the wrong file and thus be difficult to find. Electronic data interchange, or, EDI, optimizes data exchange and management, and improves b2b communication and processes. EDI includes payment, invoices, delivery confirmation, delivery, packing, and ordering.

Like many other early information technologies, EDI was inspired by developments in military logistics. The complexity of military operations that required vast quantities of data and information about transported goods inspired the first innovations in large-scale communication, which later shaped the first TDCC (Transportation Data Coordinating Committee) standards in the United States. Among the first integrated systems using EDI were Freight Control Systems. An example of this is the London Airport Cargo EDP Scheme (LACES) at Heathrow Airport, London, in which a modem-like system would forward information to agents who would directly enter information into the customs processing system, reducing the time for clearance.

EDI provides a technical basis for automated commercial “conversations” between two entities, either internal or external. The term EDI encompasses the entire electronic data interchange process, including the transmission, message flow, document format, and software used to interpret the documents. EDI is the computer-to-computer exchange of business documents in a standard electronic format between business partners.

Each term in the definition is significant:

● Computer-to-computer – EDI replaces postal mail, fax, and email. While email is also an electronic approach, the documents exchanged via email must still be handled by people rather than computers. Having people involved slows down the processing of the documents and also introduces errors. Instead, EDI documents can flow straight through to the appropriate application on the receiver’s computer (e.g., the Order Management System) and processing can begin immediately.
● Business documents – These are any of the documents that are typically exchanged between businesses. The most common documents exchanged via EDI are purchase orders, invoices, and advance ship notices. But there are many, many others such as bills of lading, customs documents, inventory documents, shipping status documents, and payment documents.
● Standard format – Because EDI documents must be processed by computers rather than humans, a standard format must be used so that the computer will be able to read and understand the documents. A standard format describes what each piece of information […]

Galvanized Steel in The Agricultural Industry

Metal and Farming: A Perfect Match

The union of farming and metalworking has led to many of civilizations technological and agricultural developments. Before the invention of farming, most early civilizations existed as gatherers and hunters. Because farming created the conditions in which people could settle, it ultimately contributed to the building of modern society and culture. Farming, and the stability farming provided humanity, led to the benefits of modernity: technology, politics, literature, the arts, and culture. Metal, like farming, helped to tilt the balance of power between mankind and nature towards mankind. Human beings could finally subdue the natural elements around them, which, beforehand, they seemingly had little to no control over.

Before the union of farm work and metal, farmers had inefficient tools to contend with the harsh conditions. These medieval farms only produced somewhere between 4.34 seeds for each seed of wheat sown. Entire village populations were constantly on the brink of starvation. Metalworkers introduced the iron plow to farmers, who had been using the ineffectual wooden plow. The new iron plows could cut through the heavy northern European soil, even during winter frost. This mingling of metal and farm work, among other technological/intellectual developments, led to the Enlightenment era and a population boom that reshaped the social order.

Today, the interaction between farming and metalworking continues to provide humanity with bountiful harvest. Although farms have become much more efficient, profit and competitive margins remain slim. Advances in metallurgy – like galvanized steel, are a keystone to modern farming operations by helping farmers to save time and money.

The Benefits of Galvanized Steel

Galvanized metal has been around for hundreds of years, although the methods for applying the zinc coating have become more sophisticated.

Galvanization improves steel’s longevity through a protective coating that prevents rust from forming. The process of hot-dip galvanizing creates a product with many benefits that other types of coatings don’t offer. For example, galvanized steel is:

Less expensive when compared with most treated steels.
Lower in maintenance cost than other coated metals – saving time on repairs and replacements.
Damage-resistant, very durable, and can withstand outdoor elements.
Self-healing in the way it’s coating provides automatic protection for damaged areas and will corrode preferentially to the steel, creating protection to the areas that are damaged.

Ready to use immediately upon delivery – it does not require additional preparation of the surface (painting/coatings, etc.) prior to installation.
