The 30% Cr alloy is designed for use in applications like flue-gas desulfurization (FGD). The higher Cr content makes this alloy especially useful when conditions of severe acid corrosion exist and when high Cl ion concentrations are present.
Because of its unique microstructure, chrome white iron offers superior abrasion resistance over other alloys, including steel. But ASTM A532 also confers specific recycling, reusing and repairing advantages over rubber and ceramic products, resulting in a lower environmental impact and significant cost savings.
Located in British Columbia, Canada, Penticton Foundry has become known for its game changing innovations in the use of ASTM A532, chrome white iron. Achieving this level of success requires constant dedication to furthering our expertise. It means investing in our people, processes and equipment, and ensuring that our customers’ expectations are exceeded every day.
A mine in British Columbia, Canada was looking for a material to replace manganese steel in their gyratory crusher liners. The mine required good wear properties, coupled with the ability to absorb great impact at low temperature.
ASTM A48 Class 30 (Related Standards – DIN GG20, BS 1452 Grade 220) is a gray cast iron. Gray iron consists of graphite flakes in a metallic matrix. When fractured, it is grayish in colour – hence the name (specifically, a fracture will follow along the graphite flakes which are gray). The low cost of production and attractive properties make gray iron one of the most commonly used ferrous alloys.
Sometimes, you get a success story that helps illustrate why many companies are shifting to chrome white iron in abrasion applications. But what are the challenges that are specific to the Oil Sands, and what is it about chrome white iron that makes it so effective there?
When materials are exposed to an abrasive environment, the media flow rubs against them, often leading to material loss over time. This can be mitigated by carefully choosing the correct material for abrasive areas.
From “chrome white iron is brittle” to “you can’t machine ASTM A532,” you’ll often hear myths when it comes to chrome white iron. But the reality is that ASTM A532 outperforms steel, AR plate and weld overlay in many applications requiring abrasion resistance.
When designing with ductile iron as an engineer you may notice that almost all ductile iron standards don’t specify a chemistry requirement. This is because the microstructure and mechanical properties can be achieved in different ways.
Why Use Chrome White Iron ASTM A532, or high chrome white iron, has superior abrasion resistance. It is particularly effective in machinery or equipment that experiences grinding, gouging abrasion or crushing.
