This company has built a reputation for crafting durable and high-strength fasteners that are designed to perform reliably even in the toughest conditions. Using premium-grade 420 stainless steel and cutting-edge production techniques, these bolts deliver impressive hardness, wear resistance, and decent corrosion protection. Mbemba Stainless caters to various industries, including petrochemical, marine, power generation, and mechanical engineering, offering Stainless Steel 420 Bolts that adhere to international standards for quality, precision, and longevity.
Stainless Steel 420 Bolts are made from martensitic stainless steel, which contains chromium (12–14%) and carbon (0.15–0.40%), along with trace amounts of manganese, silicon, and sulfur. This unique blend provides an excellent mix of hardness, strength, and corrosion resistance after undergoing heat treatment. On the mechanical side, Stainless Steel 420 boasts high tensile and yield strength, good ductility, and remarkable wear resistance. The alloy can be hardened to a Rockwell hardness of up to 50 HRC, ensuring outstanding mechanical performance in high-stress and high-temperature situations.
