Harshita Stainless is a well-respected manufacturer and supplier located in Delhi, India, specializing in high-performance Stainless Steel 422 Stud Bolts for customers in Dubai, India, and around the world. With a strong background in creating heat- and corrosion-resistant fasteners, Harshita Stainless provides SS 422 stud bolts that are known for their impressive strength, oxidation resistance, and durability even in high-temperature settings. These bolts are crafted using advanced manufacturing techniques and rigorous quality control, ensuring they meet international standards and are perfect for use in thermal, aerospace, power generation, and heavy industrial applications.
The Stainless Steel 422 Stud Bolts are made from a martensitic stainless steel alloy that includes about 12% chromium, 1% molybdenum, and 0.2–0.3% carbon, along with small amounts of tungsten and vanadium. This unique blend gives them outstanding mechanical strength and creep resistance at temperatures reaching up to 650°C. They can also be heat treated to achieve impressive hardness and tensile strength, typically ranging from 655 to 965 MPa, with a yield strength around 415 MPa. Additionally, SS 422 boasts good corrosion resistance and maintains its structural integrity under high thermal stress.
