347 Stainless hlau Bar

UNS S34700 (Qib 347)

347 stainless hlau bar, tseem hu ua UNS S34700 thiab Qib 347, yog austenitic stainless hlau ua los ntawm .08% siab tshaj carbon, 17% mus rau 19% chromium, 2% siab tshaj manganese, 9% mus rau 13% nickel, 1% siab tshaj silicon , kab ntawm phosphorus thiab sulfur, 1% yam tsawg kawg nkaus rau 10% siab tshaj plaws columbium thiab tantalum nrog qhov sib npaug ntawm cov hlau. Qib 347 yog qhov zoo rau kev pabcuam kub kub vim nws cov khoom siv zoo; nws kuj muaj kev tiv thaiv zoo heev rau intergranular corrosion tom qab raug qhov kub thiab txias hauv chromium carbide nag lossis daus ntawm 800 ° txog 1500 ° F. Nws zoo ib yam li Qib 321 hais txog kev cuam tshuam ntawm intergranular corrosion uas tau ua tiav los ntawm kev siv columbium ua ib qho chaw ruaj khov rau maximize no feature. Qib 347 tsis tuaj yeem ua kom tawv nqaij los ntawm kev kho cua sov, tab sis cov khoom siab tuaj yeem tau txais los ntawm kev txo qis.
