304 Stainless Steel Coil
  • Introduction
  • Tolerance Range

Product description:

304 is the most versatile and widly used of all the stanless steels.Their chemical composition,mechanical properties,weldability and corrosion/oxidation resistance provides the best all-round performance at relatively lower cost.


304 stainless steels have excellent low-temperature properties and do well to hardening by cold working.They can carefully controlled chemical compositions of various sub-grades provide a largr-scale of cold work hardenability,enabling them to suit for various applications by direct drawing without intermediate annealing.


Corrosion Resistance:

304 stainless steels exhibit excellent resistance to a wide range of atmospheric,chemical,textile,petroleum and food industry exposures.


Oxidation Resistance:

The maximum temperature to 304 stainless steels can be exposed continuously without apperciable scaling is about 899℃.For intermittent exposure,the maximum exposure temperature is about 816℃.


Formabilty:

304 stainless steels have very good drawability.Their combination of low yield strength and high elongation permits successful forming of complex shapes.However,these grades work harden rapidly.To relieve stresses produced in severe forming or spinning,parts should be full annealed or stressrelief annealed as soon as possible after forming.


Wachinability:

Like most other austenitic steels,these grades machine with roung and stringy chips;theredore,chip curlers can be beneficial.


Application:Corrosion resistant containers;Tableware;kitchen ware;furniture;Medical supplies;Building materials;Chemistry;Agriculture;Ship accessories
