304 and 316L stainless steel, High nickel content and corrosion-resistant. Not rust
Then why 304 stainless steel?
Type 304, with its chromium-nickel content and low carbon, is the most versatile and widely used of the austenitic stainless steels. Type 304 alloys are all modifications of the 18% chromium, 8% nickel austenitic alloy. Applications for this group of alloys are varied and all possess somewhat similar characteristics in resistance to oxidation, corrosion, and durability. All provide ease of fabrication and cleaning, prevention of product contamination and over a variety of finishes and appearances.
GENERAL PROPERTIES – TYPE 304
Type 304 stainless steels can meet a wide variety of physical requirements, making them excellent materials for applications including auto molding and trim, wheel covers, kitchen equipment, hose clamps, springs, truck bodies, exhaust manifolds, stainless atware, storage tanks, pressure vessels and piping.Road Drain Cover
