304 BA Mirror Finished Stainless Steel Coils 304BA Stainless Steel Metal Strips
General Properties
Alloy 304 a T-300 series stainless steel austenitic, which has a minimum of 18% chromium and 8% nickel. Type 304 has a maximum carbon of 0.07% . It is the standard “18/8 stainless” that is commonly found in pans and cooking tools. Alloy 304 is the most versatile and widely used alloy in the stainless steel family. Ideal for a wide variety of home and commercial applications, Alloy 304 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.
Specifications: UNS S30400
Applications:
Alloy 304 Stainless Steel is used in a wide variety of home and commercial applications, including:
Kitchen benches, sinks, troughs, equipment, and appliances
Chemical containers, including for transport
Food processing equipment, particularly in beer brewing, milk processing, and wine making
Heat exchangers
Architectural trim and molding
Woven or welded screens for mining, quarrying & water filtration
Automotive and aerospace structural use
Nuts, bolts, screws, and other fasteners in the marine environment
Construction material in large buildings
Dyeing industry
Standards:
ASTM/ASME: UNS S30400 / S30403
EURONORM: 1.4301 / 1.4303
AFNOR: Z5 CN 18.09 / Z2 CN 18.10
DIN: X5 CrNi 18 10 / X2 CrNi 19 11
Corrosion Resistance:
Resistance to moderately aggressive organic acids is a result of the 9 to 11% nickel that the 304 alloys contain.
Resistance to corrosion in oxidizing environments is a result of the 18 to 19% chromium that the 304 alloys contain.
The 304, 304L, and 304H may be considered to perform uniformly in most corrosive environments.
Heat Resistance:
Continuous use of 304 in the 800-1580°F range is not recommended if subsequent aqueous corrosion resistance is important.
Good oxidation resistance in intermittent service to 1600°F and in continuous service to 1690°F.
Properties of 304 Alloy
Welding Characteristics:
Excellent welding properties; post-weld annealing is not required when welding thin sections. Two important considerations in producing weld joints in the austenitic stainless steels are:
avoidance of cracking
preservation of corrosion resistance
Processing – Hot Forming:
To forge, heat uniformity to 2100 / 2300 °F
Do not forge below 1700 °F
Forging can be air cooled without danger of cracking
Processing – Cold Forming:
Its austenitic structure allows it to be deep-drawn without intermediate annealing, Making this the stainless steel grade of choice in the manufacturing of sinks, hollow-ware and saucepans.
These grades work harden rapidly. To relieve stresses produced in severe forming or spinning, parts should be full annealed or stress relief annealed as soon as possible after forming.
Machinability:
The use of chip breakers is advised since the chips can be stringy. Stainless steel work harden rapidly, heavy positive feeds, sharp tooling, and a rigid set-up should be used.of cut below the work-hardened layer resulting from the previous passes.
