Located in Chennai, India, Vinit Stainless is a well-known producer and supplier of high-quality stainless steel products that meet a variety of industrial demands throughout the nation. Our Stainless Steel 440B Stud Bolts, which are made to function in the most demanding environments, are a testament to our reputation for accuracy and quality. The high-strength 440B stainless steel used to make these bolts provides the ideal ratio of corrosion protection, wear resistance, and hardness. To guarantee that every product we deliver satisfies the highest standards for strength, durability, and long-term dependability in harsh environments, Vinit Stainless maintains stringent quality control.
Stainless Steel 440B Stud Bolts belong to the martensitic stainless steel family because they are mainly made of high carbon (0.75–0.95%) and chromium (16–18%). They have high hardness, excellent wear resistance, and heat-treatability due to their composition. These bolts usually have a Rockwell hardness of 58 to 60 HRC, strong yield performance, and tensile strengths of up to 760 MPa. Their chromium content improves their resistance to corrosion, and their oxidation resistance and mechanical strength guarantee their dependability in harsh industrial environments, high temperatures, and stress.
