Harshita Stainless is a prominent manufacturer and supplier located in Delhi, India, known for its high-performance Stainless Steel 446 Bolts that cater to clients in Dubai, India, and beyond. The company prides itself on providing top-notch fasteners designed for high-temperature and corrosive environments, earning a solid reputation for reliability and precision engineering. They produce SS 446 bolts in a variety of sizes and specifications to meet the needs of industries like petrochemical, thermal processing, and marine applications, ensuring these bolts are durable, strong, and resistant to oxidation, even under the toughest conditions.
Stainless Steel 446 Bolts are crafted from a ferritic alloy that contains 23–27% chromium, giving them exceptional resistance to oxidation, sulfidation, and high-temperature corrosion. These bolts not only boast good mechanical strength but also excellent scaling resistance, with a typical tensile strength of around 485 MPa and a yield strength of about 275 MPa. The material remains stable during thermal cycling and keeps its magnetic properties intact. While SS 446 bolts can’t be hardened through heat treatment, they deliver dependable performance in challenging and fluctuating temperature environments.
