Material Handling: Mild Carbon Steel vs. AR Steel vs. Stainless Steel

Well, on the Brinell scale – which measures the hardness of steel, with the higher the number meaning the harder it is – mild carbon (130-160BHN) and stainless steel (160-200BHN) are relatively similar. AR steel tends to come in between 235-550BHN. AR steels are a great choice to build a gate, valve or diverter if you deal with high ...
