Stainless Steel 309 Fasteners are high-performance fasteners made from alloy 309, which is an austenitic stainless steel. The alloy is composed of higher chromium (22-24%) and nickel (12-15%) content compared to other stainless steels, providing exceptional oxidation resistance at elevated temperatures. These fasteners are especially suitable for high-temperature applications due to t... https://www.metcoresteel.com/stainless-steel-309-fasteners-manufacturer-exporter-suppliers-stockists.html
