347 stainless steel data sheet.
Ideal for long term work life in high temperatures 800 1500ºf 347 stainless steel is also resistant to intergranular corrosion in the chromium carbide precipitation range.
347 alloys are stabilized stainless steels which offer as their main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500 f 427 to 816 c.
Columbium stabilizes this alloy making it immune to chromium carbide precipitation.
Type 347 stainless steel has slightly improved corrosion resistance over type 321 stainless steel in strongly oxidizing environments.
Alloy 347 is a stabilized stainless steel similar to type 304 with an addition of columbium and tantalum.
Verified at time of enquiry or order.
347 alloys are stabilized by the addition of columbium.
Type 347 is stabilized with columbium it is preferable for aqueous and low temperature environments due to its good resistance to intergranular attack.
Ati 321 ati 347 and ati 348 alloys offer similar resistance to general overall corrosion as the unstabilized chromium nickel ati 304 stainless.
1 4550 aisi 347 is an austenitic chromium nickel stainless steel with titanium and niobium addition.
Furthermore in service real conditions are specific for each application.
Chemical analysis weight.
Type 347 stainless steel has slightly improved corrosion resistance over type 321 stainless steel in strongly oxidizing environments.
Alloy 347 is recommended for welded applications that can not tolerate a post anneal.
