Yasin Fasteners, located in Istanbul, Turkey, is a leading manufacturer and supplier of stainless steel products, including 317 and 317L grades. Known for quality, the company offers corrosion-resistant materials that meet the needs of harsh chemical and marine environments. By using modern technology and following international standards, Yasin Fasteners delivers products that perform well and are durable. Their 317/317L stainless steel grades stand out for their high resistance to sulfuric acid, chlorides, and other harsh agents. This makes them essential in industries like chemical processing, pulp and paper, marine engineering, and petrochemicals.
317 stainless steel contains around 18 to 20% chromium, 11 to 15% nickel, 3 to 4% molybdenum, and low carbon. 317L is a low-carbon version that improves weldability and reduces carbide precipitation. These austenitic stainless steels provide higher tensile strength (515 to 620 MPa) and yield strength (205 to 275 MPa) than 316 grades. They also show excellent ductility and elongation, with high resistance to pitting and crevice corrosion. The mechanical stability of 317/317L allows them to perform well under extreme conditions, including exposure to chemicals, high temperatures, and environments prone to chloride-induced corrosion.
