AISI321 2B 1.0x1000x2000mm
AISI321 2B 1.5x1000x2000mm
二、Introduction of AISI 321 AUSTENITE
321 18Cr-9Ni-0.3Ti
Characteristics
Type 321 stainless steel is Ni-Cr-Ti austenitic stainless steel,its performance is very similar with 304,the Ti as a stabilizing element exists,but it is also a hot steel,in terms of high temperature is better than 316 l,suitable for use under 430℃~900℃ environment.321 stainless steel in different concentration,temperature,organic acid and inorganic acid,especially in oxidizing medium with good adrasion resistance.
321 stainless steel has excellent high temperature stress rupture properties and high temperature is better than that of 304 stainless steel.
Usages
Used in chemical,coal,grain boundary corrosion resistant requirements of high oil industry manufacture outdoor machine,building materials heat-resistant parts and heat treatment are difficult parts,such as:
Oil gas combustion pipe
Engine exhaust pipe
The shell of boiler,heat exchanger,furnace parts
Deadened the noise of diesel engine parts
Chemical transporter
Expansion joint
Combustion furnace pipe and dryers with spiral welded pipe
