The process of making steel has historically resulted in very high emissions of carbon dioxide (CO2). Every tonne of steel produces 1.8 tonnes of CO2, representing 9% of worldwide green-house gas emissions.
The good news is that over the years, we have made a lot of progress when it comes to the development and sustainability of material science. For example, if the Eiffel Tower was built today, it would only require 25% of the steel used for its original construction back in 1887.
We need to continue developing better ways to produce important metals such as steel for wear resistant plates and to better manage the materials that already exist today.
Wear resistant steel production has long been associated with high carbon emissions, with each tonne of steel yielding 1.8 tonnes of CO2, amounting to a staggering 9% of global greenhouse gas emissions. While using scrap steel as a substitute for iron ore and coke can help reduce CO2 emissions, it falls short of meeting the world’s steel demand. In response, innovative and sustainable methods are being explored to revolutionize the industry, many of which involve the replacement of coke. Here’s how Titus Steel is leading the way with its wear resistant steel production. (more…)
Most people refer to IRON as STEEL and STEEL as IRON. However, these are two very different products. Iron or iron ore is the fourth-most abundant element on the planet and can be found and mined in the earth to make various steels, cast iron, wrought iron, high/low alloy steels etc. Iron ore is the base element to make all grades of iron and steels, and is also an essential mineral which helps make hemoglobin in the human body.

Austenite and Martensite, in steel, refers to the microstructure of steel at the atomic level. During the tempering process or cooling, Austenite is transformed into Martensite. The ideal wear resistant steel would have a combination of retained Austenite as well as some transformed Martensite. (more…)
All steel mills produce standard sizes of bars (i.e. flat, round, square) and plates (i.e. 48” x 96”, 96” x 240”, 120” x 288” etc.). Consequently, the fabricator must have equipment to cut the bars or plate to a size which they can use for further processing. Other than shearing, sawing, grinding or water jet, wear resistant steel is usually cut using heat to melt the material. There are 3 main processes and each has its advantages. (more…)
Impact resistance in wear resistant steel is usually defined as the amount of energy that a material can withstand when it is suddenly hit with a load or force. Think in terms of a steel plate or steel parts being hit by a very hard object like rocks hitting a grizzly screen. It is measured as the amount of force required to crack or deform the steel, and is measured in foot-pounds per inch or joules per centimeter. (more…)
When working with any steel, but in particular wear resistant steels, it is imperative that you know the grain direction of the plate.
A steel plate’s grain direction comes from the mill’s rolling process, which stretches the metallurgical structure of the material. The grains run parallel to the rolling direction. (more…)
Not all steels are the same. In fact, there are over 3,500 different grades of steel, each encompassing unique physical, chemical, and mechanical properties to make them ‘custom-tailored’ to suit specific applications. Even within certain groups of steel like Abrasion and Wear-Resistant steels (AR steel) there are many different grades, each with different chemistry and mechanical properties that yield different performance.
