Khaleed Stainless stands out as a top manufacturer and supplier of Stainless Steel 440C Stud Bolts in Riyadh, Saudi Arabia, providing high-performance fastening solutions for critical applications. Known for its superior hardness, wear resistance, and strength, Stainless Steel 440C is a high-carbon martensitic stainless steel. Our 440C stud bolts are crafted with precision to meet strict dimensions and quality standards, ensuring they are durable and reliable even in the toughest environments. At Khaleed Stainless, we offer Stainless Steel 440C Stud Bolts that excel in various industries, including aerospace, automotive, petrochemical, and engineering.
Stainless Steel 440C Stud Bolts are made up of high carbon (0.95–1.20%) and chromium (16–18%), along with controlled amounts of manganese, silicon, and molybdenum. This unique blend gives them impressive hardness, with tensile strength reaching up to 760–800 MPa and yield strength around 450 MPa, achieving a Rockwell hardness of up to 58 HRC when heat-treated. The material boasts excellent wear resistance and moderate corrosion resistance, making it perfect for mechanical applications that demand strength and durability. However, it’s worth noting that it’s not as corrosion-resistant as austenitic grades, particularly in environments rich in chlorides.
