With its main office in Kolkata, India, Aditya Stainless is a leading producer and supplier of premium stainless steel goods, catering to customers all over the nation. The business is well-known for its exceptional product quality and precision engineering, and it specializes in providing long-lasting solutions for a variety of industries. Stainless Steel 440C Stud Bolts are one of its main products; they are composed of premium martensitic stainless steel, which is renowned for its remarkable hardness, resistance to wear, and ability to prevent corrosion. Designed to withstand harsh conditions, these bolts are perfect for heavy-duty industrial, marine, and aerospace applications where exceptional fastening strength is essential.
About 16–18% chromium, 0.95–1.20% carbon, and trace amounts of silicon, manganese, and molybdenum make up stainless steel 440C Stud Bolts. Up to 60 HRC of hardness can be attained by heat-treating this high-carbon martensitic stainless steel. The bolts have outstanding resistance to wear and abrasion, a tensile strength of approximately 760–980 MPa, and a yield strength of approximately 450 MPa. They are ideal for high-load, high-friction, and abrasive service environments because they are mechanically tough and have moderate corrosion resistance, particularly when hardened.
