I-347H i-stainless steel chemical composition

I-alloy 347H yintsimbi ezinzileyo, i-austenitic, i-chromium equkethe i-columbium evumela ukupheliswa kwe-carbide precipitation, kwaye, ngenxa yoko, i-intergranualr corrosion.I-alloy 347 izinziswa ludityaniso lwechromium kunye ne-tantalum kwaye inikezela ngeempawu eziphezulu zokukrazula kunye noxinzelelo lwe-alloy 304 kunye ne-304L enokuthi isetyenziselwe utyhileko apho uvakalelo kunye ne-intergranualr corrosion ixhalabile.Ukongezwa kwe-columbium kukwavumela i-Alloy 347 ukuba ibe nokumelana nokugqwesa okugqwesileyo, ngaphezu koko kwe-alloy 321. I-347H yindlela ephezulu yokwakheka kwekhabhoni ye-Alloy 347 kwaye ibonisa ubushushu obuphezulu obuphuculweyo kunye neempawu ezirhubuluzayo.I-Haosteel Stainless inventory ngoku iquka i-Alloy 347/347H (UNS S34700/S34709) kwiphepha, i-coil sheet, ipleyiti, ibha ejikelezileyo, i-flat bar kunye neemveliso ze-tubular.

Usetyenziso

I-alloy 347H isetyenziswa rhoqo ekwenzeni izixhobo, ekufuneka zifakwe kwinkonzo phantsi kweemeko ezinobungozi ezinobungozi, kwaye ziqhelekile kumashishini okucoca i-petroleum.

Ukuxhathisa ukonakala:

.Inikeza ukuchasana okufanayo ngokubanzi, ukubola ngokubanzi njenge-Alloy 304

.Isetyenziselwa izicelo apho ingxubevange efana ne-alloy 304 isesichengeni kukonakala kwe-intergranualr

.Ngokuqhelekileyo isetyenziselwa izixhobo ezidityanisiweyo ezinzima ezingenako ukukhutshwa kunye nezixhobo

esetyenziswa phakathi kwama-800 ukuya kwi-150°F (427 UKUYA 816°C)

.I-alloy 347 ikhethwa ngaphezu kweAlloy 321 yamanzi kunye nezinye iindawo zobushushu obuphantsi.

.Ngokuyintloko isetyenziswa kwiindawo eziphakamileyo zobushushu apho ukuxhathisa kunyanzelekile, oko kuthintele i-intergranualr corrosion kumanqanaba asezantsi.

.Ichaphazeleka kuxinzelelo lokuqhekeka kwe-corrosion

.Ibonisa ukuxhathisa i-oxidation efana nazo zonke ezinye ii-18-8 ze-austenitic stainless steels
