Harsh Metalloys, a prominent manufacturer and supplier located in Mumbai, India, proudly presents a wide array of Stainless Steel 201 Nuts. These nuts are celebrated for their remarkable durability, affordability, and resistance to wear and corrosion. Crafted to excel in demanding fastening applications, they adhere to international standards like ASTM and DIN. Stainless Steel 201 is an austenitic blend of chromium, nickel, and manganese, offering solid mechanical strength and decent corrosion resistance, making it a budget-friendly alternative to the 304 grade. Harsh Metalloys guarantees precise dimensions, top-notch threading, and timely delivery, catering to sectors such as automotive, construction, railways, and general manufacturing.
When it comes to the composition and mechanical properties of Stainless Steel 201 Nuts, they consist of Chromium (16–18%), Nickel (3.5–5.5%), Manganese (5.5–7.5%), Carbon (≤0.15%), Silicon (≤1%), Phosphorus (≤0.060%), and Sulfur (≤0.030%). The elevated manganese content allows for reduced nickel usage while still preserving austenitic characteristics. In terms of mechanical properties, these nuts boast a tensile strength ranging from 520 to 750 MPa, a minimum yield strength of 275 MPa, an elongation of about 40%, and a hardness of up to 95 HRB. These attributes make 201 nuts perfect for general-purpose fastening, especially in indoor settings or less aggressive environments where strength, formability, and moderate corrosion resistance are essential.

Providing excellent strength for hard surfaces, these SS 210 Heavy Hex nuts are designed for high-stress environments. Available in sizes from M6 to M36, they are perfect for use in industrial machinery, boilers and heavy equipment.
Providing a large surface area for efficient torque application, this rectangular shape ensures a tight fit in tight spaces. Available in sizes from M6 to M24, they are ideal for industrial machinery and construction applications.
Stainless Steel 201 Nuts are a popular choice in various industries where you need decent corrosion resistance and solid mechanical strength. You’ll often find them in automotive parts, railway fittings, electrical enclosures, architectural structures, and appliances. They’re also handy for light structural assemblies, furniture making, and equipment housings. Thanks to their great formability, they’re perfect for cold forming, and their cost-effectiveness makes them a go-to for projects on a budget. Just keep in mind that since they don’t resist corrosion as well as 304 or 316 grades, it’s best to use them indoors or in dry conditions, away from harsh chemicals and moisture.
