Low carbon content means less carbide precipitation in the heat-affected zone during welding and a lower susceptibility to intergranular corrosion. Essentially non-magnetic, becomes slightly magnetic when cold worked. High ductility, excellent drawing, forming, and spinning properties.
Better corrosion resistance than Type 302.

Properties quoted below are guideline figuresonly nad should not be used for any design purposes.Metal Ferrous Metal Heat Resisting Stainless Steel T 300 Series Stainless SteelĪustenitic Cr-Ni stainless steel. Stainless steel work hardens rapidly, heavy positive feeds, sharp tooling, and a rigid set-up should be used. The use of chip breakers is advised since the chips can be stringy. Two important considerations in producing weld joints in the austenitic stainless steels are: Grade 304L is more resistant to carbide precipitation and can be heated into the above temperature range.Įxcellent welding properties post-weld annealing is not required when welding thin sections.Continuous use of 304 in the 800-1580☏ range is not recommended if subsequent aqueous corrosion resistance is important.Good oxidation resistance in intermittent service to 1600☏ and in continuous service to 1690☏.Grade 304L is preferred for use in environments sufficiently corrosive to cause intergranular corrosion of welds and heat-affected zones on susceptible alloys.At times, grade 304L may show a lower corrosion rate than the higher carbon Alloy 304 otherwise, the 304 and 304L may be considered to perform uniformly in most corrosive environments.Resistance to corrosion in oxidizing environments is a result of the 18 to 19% chromium that the 304 alloys contain.Resistance to moderately aggressive organic acids is a result of the 9 to 11% nickel that the 304 alloys contain.Woven or welded screens for mining, quarrying & water filtration.Chemical containers, including for transport.Automotive and aerospace structural use.Food processing equipment, particularly in beer brewing, milk processing, and winemaking.Nuts, bolts, screws, and other fasteners in the marine environment.Construction material in building bridges, dams, roads, airports, canals, and buildings.
Grade 304 / 304L Stainless Steel is used in a wide variety of commercial and industrial applications, including: 304 / 304L is available in sheet, sheet coil, plate, plate coil, round bar, processed flat bar and tubular products for further manufacturing. This range of carbon in the steels affects the corrosion resistance. The only difference between them is the carbon content. Grade 304 / 304L stainless steel has a minimum of 18% chromium and 8% nickel.
