Product Description

Product Description

GRADE 304 / 304L STAINLESS STEEL SPECIFICATION

Grade 304 / 304L stainless steel has a minimum of 18% chromium and 8% nickel. The only difference between them is the carbon content. Type 304 has a maximum carbon of 0.07% .Type 304L has maximum carbon of 0.030 %. This range of carbon in the steels affects the corrosion resistance. 304 / 304L is available in sheet, sheet coil, plate, plate coil, round bar, processed flat bar and tubular products for further manufacturing.

Applications

Grade 304 / 304L Stainless Steel is used in a wide variety of commercial and industrial applications, including:

• Construction material in building bridges, dams, roads, airports, canals, and buildings
• Nuts, bolts, screws, and other fasteners in the marine environment
• Food processing equipment, particularly in beer brewing, milk processing, and winemaking
• Architectural trim and molding
• Automotive and aerospace structural use
• Chemical containers, including for transport
• Heat exchangers
• Woven or welded screens for mining, quarrying & water filtration
