Harshita Stainless, a well-known manufacturer and supplier located in Delhi, India, specializes in top-notch Stainless Steel 317L Nuts that are designed to withstand high levels of corrosion and deliver long-lasting performance in tough chemical and marine settings. With a reputation for precision manufacturing and rigorous quality control, Harshita Stainless ensures that their 317L nuts meet international standards, making them perfect for industries that require exceptional strength and resistance to chemical damage. Thanks to their excellent weldability and low carbon content, these nuts are perfect for applications involving acidic solutions, exposure to chlorides, and high-stress conditions, guaranteeing secure and durable fastening across a variety of industrial operations and structures.
Stainless Steel 317L is a low-carbon, molybdenum-rich austenitic stainless steel alloy that contains 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and ≤0.03% carbon. This unique composition boosts resistance to pitting and crevice corrosion while enhancing weldability. The 317L nuts boast a tensile strength of 515–620 MPa, yield strength of 205–275 MPa, elongation of 35–50%, and a hardness rating of around 80–90 HRB, making them perfect for environments where corrosion and chemical exposure are prevalent.
