Stainless steel 304 is an austenitic grade that can be severely deep drawn. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans.
Our 304 Grade Stainless Steel Coil has excellent corrosion resistance, good resistance to intergranular corrosion and good processing properties. Annealing of cold-rolled strips recrystallizes cold-rolled coils, eliminating cold-rolling work hardening, restoring plasticity to achieve expectations.
Chemical Composition of Stainless Steel Coil
The difference between the three processes of quenching, annealing and tempering
1. Quenching: The steel is heated to a temperature above the critical temperature, kept for a period of time, and then rapidly cooled in water, brine or oil (individual materials in the air) to obtain high hardness of the steel. Application: Used to increase the hardness and strength limit of steel, but quenching will cause internal stress to make steel brittle, so it must be tempered after quenching.
2. Annealing: The steel is heated above the critical temperature, kept for a period of time, and then slowly cooled (generally cooled in the furnace) to reduce the hardness of the steel. Application: It is used to eliminate internal stress of cast, forged and welded parts, reduce hardness, facilitate cutting, refine metal grains, improve structure and increase toughness.
3. Tempering: It is to heat the hardened steel to a certain temperature at a critical point, keep it for a period of time, and then cool it to room temperature to improve the plasticity and impact of the steel. Application: It is used to eliminate the brittleness and internal stress after quenching and improve the plasticity and impact of steel.
◆ Corrosion Resistance: 304 stainless stands up excellently in a range of atmospheric environments even when exposed to corrosive elements.
◆ Heat Resistance: Continuous use of 304 between 425-860⁰C is not recommended. Although it is resistant to carbide precipitation and can be heated in high temperatures.
◆ Easy to weld with excellent weldability.
◆ Excellent strength and toughness in high temperatures
