Khoom Taw qhia

Alloy 347 (UNS S34700)yog niobium stabilized austenitic stainless hlau yeeb nkab nrog zoo dav corrosion kuj thiab me ntsis kuj zoo dua 321 (UNS S32100) nyob rau hauv muaj zog oxidizing tej yam kev mob.347 stainless hlau yeeb nkabmuaj kev tiv thaiv zoo heev rau intergranular corrosion tom qab raug chromium carbide nag lossis daus kub ntawm 800 - 1500 degree F (427 - 816 degree). Nws kuj muaj qhov kub thiab txias toughness zoo. Nws yog non-magnetic nyob rau hauv lub annealed mob. Peb cov neeg muag khoom muab ob qho tib si SS 347 welded kav thiab SS 347 seamless kav.

347 Hlau Yeeb VS 304/316

SS 347 yeeb nkab muaj ntau chromium thiab muaj niobium ntxiv los pab tswj cov khoom ruaj khov thiab tiv thaiv cov nag lossis daus ntawm chromium carbides. Qhov no ua rau nws tiv taus intergranular corrosion dua li 304 stainless hlau. Nyob rau hauv cov nqe lus ntawm nws cov khoom, 316 stainless hlau yog feem ntau ductile thiab formable tshaj 347 stainless hlau.
