GENERAL PROPERTIES

Alloy 304L a T-300 series 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. Alloys 304L is the most versatile and widely used alloy in the stainless steel family. Ideal for a wide variety of home and commercial applications, Alloys 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.


APPLICATIONS

Alloy 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

CORROSION RESISTANCE

  • 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.
  • At times, alloy 304L may show a lower corrosion rate than the higher carbon Alloy 304; otherwise, the 304, 304L, and 304H may be considered to perform uniformly in most corrosive environments.
  • Alloy 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.
  • CContinuous 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.

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:


  • preservation of corrosion resistance
  • avoidance of cracking

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.
