ASTM 321 stainless steel and 347 stainless steel

ASTM 321 stainless steel and 347 stainless steel are important metal in stainless steel.We are ASTM 321 stainless steel manufacturers in China.

ASTM 321 stainless steel and 347 stainless steel are the basic austenitic 18/8 steel (Grade 304) stabilised by Titanium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Grade 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.

Like other austenitic grades,ASTM 321 and 347 have excellent forming and welding characteristics, are readily brake or roll formed and have outstanding welding characteristics. Post-weld annealing is not required. They also have excellent toughness, even down to cryogenic temperatures. Grade321 does not polish well, so is not recommended for decorative applications.

ASTM 321 stainless steel and 347 stainless steel are commonly used in high temperature environments 800-1500 ° F (427-816 ° C) for long-term operation. If the application only involves welding or short heating time, can be replaced by 304L.
