ASTM A312 TP321H Stainless hlau yeeb nkab yog dab tsi?
ASTM A 312 TP 321 Hstainless hlau yeeb nkab yog ibhigh carbon version ntawm TP321 stainless hlau yeeb nkab, ruaj khov nrog titanium (Ti) thiab tsim los rau siab -cov kev pabcuam kub. Nws yog tsim nyob rau hauv ASTM A312 / ASME SA312 tus qauv thiab yog dav siv nyob rau hauv siab tshuab, boilers, tshav kub exchangers, thiab petrochemical pipelines.
Qhov "H" hauv TP321H sawv rauCov pa roj carbon ntau, uas ua rau kom muaj zog tensile ntawm qhov kub siab, ua rau nws haum rau ntev - lub sij hawm thermal stress puag ncig piv rau tus qauv TP321.
