Yasin Fasteners, being a reputable Turkish manufacturer and exporter of stainless steel 317 and 317L washers, suits applications that need higher corrosion resistance and sound mechanical performance. These washers are constructed using high-alloy austenitic stainless steel, which ensures high durability against tough chemical and marine environments. Yasin Fasteners offers a range of washers in 317 and 317L grades to the chemical processing, marine, pulp and paper, and power generation industries. With precise following of international standards, the company supplies standard as well as custom washers to suit specific application needs.
Stainless steel 317 and 317L washers have increased molybdenum content (approximately 3–4%) compared to the typical 316 grade, showing enhanced resistance to pitting, crevice corrosion, and acidic conditions. Grade 317L is the low-carbon variant of 317, which minimizes the tendency for carbide precipitation on heating, thus suitable for welded applications. They have good tensile strength, high ductility, and good resistance to chemical attack. They can be used in high-temperature and corrosive environments where normal stainless steels cannot endure or get degraded with time.

To satisfy our clients needs by providing high quality products at competitive price as per the schedule and to maintain long term relationship with our clients.
Stainless steel 317/317L washers are traditionally employed in chemical and petrochemical facilities, particularly in equipment that deals with sulfuric, acetic, formic, and tartaric acids. For marine environments, they provide stable performance in saltwater applications. They also apply to pulp and paper treatment, power generation, and pollution control devices. These washers distribute load evenly, prevent surface damage, and ensure joint integrity under mechanical stress and thermal stress. They are corrosion-resistant, mechanically strong, and weldable, and these properties make them a dependable fastening system in harsh industrial conditions.
We ensure the highest quality for our Stainless Steel 317/317L Washers through rigorous testing, including Hardness, Chemical Analysis, Positive Material Identification (PMI), Flattening, Micro and Macro Tests, Pitting Resistance, Flaring, and Intergranular Corrosion (IGC) Tests. Each product is accompanied by detailed documentation, such as a commercial invoice, packaging list, Certificate of Origin, and a Guarantee Letter. Third Party Inspection Certificates are also provided to affirm our commitment to industry-leading standards.
