Dab tsi yog TTM A312 khoom siv?

ASTM A312yog tus qauv muab los ntawm ASTM thoob ntiaj teb rau seamless rau seamless, welded, thiab hnyav-ua haujlwm ustenitic stainless hlau thiab kev corrosive serves .

Cov qib kawm nyob hauv Astm A312:

TPPP04 / TPP04L- Tsim dav-hom stainless hlau

TP316 / TPP36L- Chloride-tiv taus, zoo tagnrho rau cov tubrog nkoj / tshuaj siv

Tp321 / TPp37- stabilized rau high-kub cycling

Teng310Ss, TPP17L, TP904L- Rau kev txhoj puab ntau lossis ntau dua

Cov ntaub ntawv no tau paub txog lawv cov khoom lag luam corrosion zoo heev, lub zog, thiab siab ua kev ua haujlwm .

Dab tsi yog phab ntsa tuab ntawm Astm A312 yeeb nkab?

ASTM A312 kav yog tsim hauv:
