Harshita Stainless, a reputable manufacturer and supplier located in Delhi, India, is well-regarded for providing top-notch Stainless Steel 317L Fasteners that excel in highly corrosive and chemically aggressive settings. With a strong focus on quality, precision, and customer satisfaction, Harshita Stainless offers a diverse range of 317L fasteners designed to meet the needs of various industries, including chemical processing, pharmaceuticals, marine, and pulp and paper. These fasteners are not only corrosion-resistant and durable but also perfect for applications that require low carbon content, ensuring outstanding weldability, strength, and long-lasting reliability in both high-moisture and high-temperature conditions.
Stainless Steel 317L is a low-carbon austenitic alloy made up of 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and ≤0.03% carbon, which boosts its corrosion resistance and enhances weldability. These fasteners deliver a tensile strength of 515–620 MPa, yield strength of 205–275 MPa, elongation of 35–50%, and hardness ranging from 80–90 HRB. The low carbon content helps to prevent carbide precipitation during welding, making Stainless Steel 317L Fasteners perfect for use in corrosive and welded environments that demand long-term structural integrity.
