With a strong focus on precision manufacturing and consistent quality, the company produces washers that meet international standards and industrial specifications. Stainless Steel 409 Washers from Lina Fasteners offer good oxidation resistance and thermal stability, making them a cost-effective choice for heat-exposed environments. Through technical expertise and customer-focused service, Lina Fasteners supports automotive, power generation, industrial machinery, and engineering sectors with durable fastening solutions.
Stainless Steel 409 Washers are produced from a ferritic stainless steel alloy containing approximately 10.5–11.75% chromium, with titanium added for stabilization. This composition enhances resistance to oxidation and minimizes intergranular corrosion during thermal cycling. Mechanically, 409 Washers provide moderate tensile and yield strength, good ductility, and stable performance at elevated temperatures. Although their corrosion resistance is lower than austenitic grades, they perform reliably in high-temperature and mildly corrosive environments where thermal stability is essential.
