Abrazo 400, made by Luke Steel in Houston, is a medium-hard abrasion-resistant plate with a nominal hardness of 400 HBW. It offers great durability while being easier to form and weld than harder grades. This material suits applications with moderate wear demands but needs cost-effective performance and fabrication flexibility. Its consistent quality and domestic supply make it a dependable choice for OEMs and fabricators.
Abrazo 400 consists of low-alloy steel including carbon, manganese, and minor amounts of chromium and molybdenum. It has a yield strength close to 1000 MPa, a tensile strength of about 1100 MPa, and an elongation of 12–14%. Its Brinell hardness is approximately 400 HBW. The impact toughness typically exceeds 35 ft-lb at –20 °C, and this steel is compatible with typical welding methods using standard consumables and preheating.
