347H simbi isina tsvina yakakoswa chubhu
Alloy 347H isimbi yakagadzikana, austenitic, chromium ine columbium inobvumira kubviswa kwecarbide kunaya, uye, nekudaro, intergranualr corrosion.Alloy 347 inodzikamiswa neakawedzerwa echromium uye tantalum uye inopa yakakwira inokambaira uye kusagadzikana kuputika zvivakwa pane alloy 304 uye 304L iyo inogona zvakare kushandiswa kufumura uko sensitization uye intergranualr corrosion zvine chekuita.Kuwedzerwa kwecolumbium kunobvumirawo Alloy 347 kuti ive neyakanakisa corrosion resistance, yakatokunda iyo yealloy 321. 347H ndiyo yakakwirira carbon composition form yeAlloy 347 uye inoratidza yakavandudzwa tembiricha yepamusoro uye zvinokambaira.Haosteel Stainless inventory ikozvino inosanganisira Alloy 347/347H (UNS S34700/S34709) mune pepa, sheet coil, ndiro, bhara rakatenderedzwa, yakagadziriswa flat bar uye tubular zvigadzirwa.
