321 stainless steel coil

Description

321 stainless steel coil
 
    321 stainless steel is one member from austenitic family, with stabilized Titanium.as a result 321 stainless steel is more heat resistant than 304 material,usually could used in 900 degrees circumstance, while 304 is normal up to 500 degrees at most.at the same time,321 stainless steel with the features of austenitic. such as excellent forming,welding characteristics and good general corrosion resistance.
