What are Stainless Steel 304 Fasteners?

Stainless Steel 304 Fasteners are fastener elements made of austenitic stainless steel grade 304 also called UNS S30400 or EN 1.4301. These fasteners consist of about 18% chromium and 8% nickel, which provide them with excellent resistance to oxidation, moisture, chemicals and atmospheric corrosion. Due to its strength, durability and cost-effectiveness SS 304 Fasteners are used in food processing, chemical plants, construction, marine equipment, power generation and general engineering applications.
