ASTM A240 304L stainless steel sheet, 2B BA NO.4 mirror finish, 1219*2438mm
Description:
304L stainless steel austenitic, which has a minimum of 18% chromium and 8% nickel. Type 304L has a carbon maximum is 0.030. It is the standard “18/8 stainless” that is commonly found in pans and cooking tools. Stainless steel 304L is the most versatile and widely used alloy in the stainless steel family. Ideal for a wide variety of home and commercial applications, Inox 304L exhibits excellent corrosion resistance and has a high ease of fabrication, outstanding formability. The austenitic stainless steels are also considered to be the most weldable of the high-alloy steels and can be welded by all fusion and resistance welding processes.
Chemical composition:
| C | Si | Mn | P | S | Cr | Ni | N |
| ≤ 0.03 | ≤ 1.00 | ≤ 2.00 | ≤ 0.045 | ≤ 0.03 | 18.0 - 20.0 | 8.0 - 10.5 | ≤ 0.10 |
Physical Properties:
Annealed:
Ultimate Tensile Strength – 70 KSI min (485 MPA min)
Yield Strength (0.2% Offset) – 25 KSI min (170 MPA min)
Elongation – 40% min
Hardness – HRB88 max (201HV max)
Corrosion Resistance:
Resistance to corrosion in oxidizing environments is a result of the 18 to 19% chromium that the 304 stainless steel contain.
Resistance to moderately aggressive organic acids is a result of the 9 to 11% nickel that the 304 stainless steel contain.
At times, stainless steel 304L may show a lower corrosion rate than the higher carbon stainless steel 304; otherwise, the 304, 304L, and 304H may be considered to perform uniformly in most corrosive environments.
Stainless steel 304L is preferred for use in environments sufficiently corrosive to cause intergranular corrosion of welds and heat-affected zones on susceptible alloys.
Heat Resistance:
Good oxidation resistance in intermittent service to 1600°F and in continuous service to 1690°F.
Continuous use of 304 in the 800-1580°F range is not recommended if subsequent aqueous corrosion resistance is important.
Grade 304L is more resistant to carbide precipitation and can be heated into the above temperature range.
Applications:
304L Stainless Steel is used in a wide variety of home and commercial applications, including:
Food processing equipment, particularly in beer brewing, milk processing, and wine making
Kitchen benches, sinks, troughs, equipment, and appliances
Architectural trim and molding
Automotive and aerospace structural use
Construction material in large buildings
Chemical containers, including for transport
Heat exchangers
Nuts, bolts, screws, and other fasteners in the marine environment
Dyeing industry
Woven or welded screens for mining, quarrying & water filtration
