347 stainless steel heat treatment

Welding of Austenitic Stainless Steel - Part 2 - TWI

Carbides present in the HAZ of an austenitic stainless steel dissolve on heating and reform on cooling during the welding heat cycle.Unfortunately,these new precipitates form preferentially as chromium carbides on the grain boundaries,depleting chromium from the region immediately adjacent to the boundary,resulting in a local loss of THE HEAT TREAT DOCTOR Stainless Steels Part TwoJun 14,2006 347 stainless steel heat treatment#0183;Heat treating of stainless steels depends to a great extent on the type (wrought or cast) and grade of stainless steel,as well as the reason for the treatment,most often to ensure that the properties altered during fabrication are restored (e.g.corrosion resistance,ductility,or hardness) so that the stainless steel component can perform in Stainless steel 347H and PWHT AMARINENov 04,2019 347 stainless steel heat treatment#0183;This level of defense is common and the stainless steel base metals e.g.Types 321 and 347 are generally purchased in the thermally stabilized condition and placed in service in the as welded/fabricated condition,depending on severity of service,i.e.,no further stabilization heat treatment is needed after the welding process.

Type 347 stainless steel is a columbium/tantalum stabilized austenitic stainless steel.Similar to 321 stainless,it has good intergranular-corrosion resistance compared to typical 18-8 type alloys.With the addition of columbium and tantalum,which have a stronger affinity for carbon than chromium,the carbides will tend to randomly precipitate at the grain boundaries rather than form Stainless Steel Information Composition - Alpha KnifeMaximum Hardness 217 Brinell or 18 HRC.Cannot be hardened by heat treatment.347 Similar to 321 stainless,347 uses columbium to resist to intergranular corrosion.It can be used in applications requiring repeated heating in the range of 800F to 1650F.Stainless Steel 347/347H Manufacturers,Suppliers FactoryHeat Treatment and Resistance of Stainless Steel 347/347H Annealing.1850-2000 F (1010-1093 C),water quenches.This process will result in maximum ductility.Annealing temperature range is 1800 to 2000 347 stainless steel heat treatment#176;F.May be stress relief annealed within the carbide precipitation range of 800 to 1500 347 stainless steel heat treatment#176;F without any danger of subsequent intergranular corrosion
