Harshita Stainless, located in Delhi, India, is a well-respected manufacturer and supplier of high-quality stainless steel fasteners, including Stainless Steel 436 Nuts. These nuts are specifically designed to perform well in moderately corrosive and high-temperature settings, making them a popular choice in various industries like automotive, kitchen equipment, and heat exchanger systems. Crafted from premium-grade raw materials and utilizing modern production techniques, our nuts ensure durability, a great surface finish, and precise dimensions. At Harshita Stainless, we focus on customer satisfaction by delivering reliable fastening solutions that adhere to international quality standards, along with efficient service and timely delivery throughout India and beyond.
Stainless Steel 436 Nuts are crafted from ferritic stainless steel, which contains about 16–18% chromium and is stabilized with molybdenum and columbium (niobium). The inclusion of molybdenum boosts corrosion resistance, especially against chlorides and reducing acids. These nuts offer moderate tensile strength (around 380–450 MPa), good oxidation resistance, and enhanced thermal conductivity. SS 436 also excels in resisting stress corrosion cracking and pitting. With a low carbon content, they are easy to weld and form, making them perfect for heat-resistant applications while maintaining their structural integrity in moderately aggressive environments.
