With a keen emphasis on engineering precision, high-quality materials, and ensuring customer satisfaction, Harshita Stainless provides fasteners that adhere to international standards for durability, reliability, and strength. These fasteners are particularly well-suited for use in the chemical, marine, and pharmaceutical sectors. Offered in a variety of sizes and finishes, the Stainless Steel 317L Fasteners from Harshita Stainless are known for their long-lasting service life and ability to withstand harsh operating conditions.
Stainless Steel 317L is a low-carbon, molybdenum-bearing austenitic stainless steel alloy that typically contains around 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a maximum of 0.03% carbon. This unique composition significantly boosts its corrosion resistance, especially in acidic and chloride-heavy environments. SS 317L fasteners boast a tensile strength ranging from 485–620 MPa, a yield strength of about 170–310 MPa, and an elongation of 40–50%, with hardness levels between 70–90 HRB. The low carbon content not only enhances weldability but also minimizes the risk of intergranular corrosion, making these fasteners perfect for both welded and high-performance chemical applications.
