Their dedication to quality, technical support, and timely delivery has established them as a reliable partner for industries like mining, construction, cement, and heavy engineering.
The 400 Brinell Hardness Number Sheets and Plates are crafted from quenched and tempered alloy steels, featuring a carefully controlled chemical composition. This steel typically includes carbon along with alloying elements such as chromium, manganese, and molybdenum, all of which enhance hardness, strength, and wear resistance. Mechanically, these plates boast a nominal hardness of around 400 HBW, offering excellent abrasion resistance while still maintaining good impact toughness. They also provide high tensile strength, good formability, and weldability when proper fabrication techniques are applied.
