Renowned for their precision engineering and exceptional strength, these nuts are crafted to meet international quality standards and serve a variety of industrial needs. Aditya Stainless provides SS 442 nuts in multiple sizes and finishes, ensuring outstanding corrosion resistance, durability, and performance even in high-temperature settings. With a strong focus on innovation, quality, and customer satisfaction, they deliver Stainless Steel 442 Nuts to sectors such as automotive, aerospace, power generation, and petrochemicals throughout Kolkata and India, all while ensuring timely delivery and competitive pricing.
Stainless Steel 442 Nuts are crafted from a ferritic stainless steel alloy that contains about 18% chromium along with trace amounts of manganese, silicon, and carbon. This unique blend gives SS 442 remarkable resistance to oxidation, scaling, and corrosion, especially in high-temperature conditions. Its mechanical properties boast a tensile strength ranging from 450 to 620 MPa, a yield strength of 280 MPa, and moderate elongation. Additionally, SS 442 maintains good creep resistance and structural stability up to 1000°C, making it ideal for demanding industrial applications that require high thermal and mechanical performance.
