Aditya Stainless, based in Kolkata, India, stands out as a top manufacturer and supplier of Stainless Steel 422 Bolts. We specialize in providing high-strength, heat-resistant fasteners that are essential for critical industrial applications. SS 422 is a martensitic stainless steel celebrated for its remarkable mechanical properties at elevated temperatures, making it perfect for high-stress environments. Our bolts are crafted to meet stringent industry standards, ensuring exceptional tensile strength, corrosion resistance, and dimensional stability. Aditya Stainless caters to various sectors, including aerospace, power generation, marine, and defense, with precision-engineered 422 bolts that guarantee durability, performance, and safety in challenging thermal and mechanical conditions.
Stainless Steel 422 Bolts are made up of chromium (11–13%), molybdenum (0.90–1.25%), tungsten (0.75%), and carbon (0.20–0.25%), along with small amounts of vanadium and nickel to enhance strength and heat resistance. These bolts boast a tensile strength ranging from 690–1030 MPa, a yield strength of about 450–690 MPa, and a Rockwell hardness of up to 45 HRC. After undergoing proper heat treatment, SS 422 bolts retain impressive mechanical properties even at elevated temperatures (up to 600°C). They also provide good corrosion resistance in mild environments while maintaining their strength and hardness under prolonged thermal and mechanical stress.
