ASTM A312 253MA Stainless Hlau Seamless Tube

316L stainless hlau kauj yog austenitic qis- carbon hlau. Vim nws cov ntsiab lus molybdenum siab thiab cov ntsiab lus tsis tshua muaj carbon, nws pom zoo corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv chloride - nplua nuj ib puag ncig. Nws lub ntsiab zoo muaj xws li weldability zoo heev (tsis tshua muaj kev pheej hmoo ntawm carbide nag lossis daus), zoo mechanical zog, thiab toughness, ua rau nws zoo tagnrho rau kev thov xws li tshuaj, shipbuilding, thiab zaub mov ua. Nyob ntawm daim ntawv thov, nws cov txheej txheem kho saum npoo muaj ntau yam los ntawm cov txheej txheem kub kub- dov tiav mus rau polishing thiab lwm yam kev kho tshwj xeeb.

Dab tsi yog cov khoom ntawm 316L stainless hlau?

Vim nws cov ntsiab lus ntau dua nickel thiab molybdenum, qib no ntawm stainless hlau yog resistant rau pitting thiab crevice corrosion tshaj 304 stainless hlau. Tsis tas li ntawd, 316/316L stainless hlau nthuav tawm lub zog tensile zoo heev, lub zog nkag, thiab kev ntxhov siab tawg lub zog ntawm qhov kub thiab txias, thaum tseem muaj cov qauv zoo heev thiab weldability.

ASTM A312 S30815 stainless hlau raj yog siab -kev ua tau zoo seamless austenitic stainless hlau raj tsim los rau qhov kub siab tshaj - kub oxidizing ib puag ncig. Nws nthuav tawm zoo heev thiab ntev - oxidation thiab scaling kuj nyob rau hauv huab cua- raug rho tawm haujlwm ib puag ncig, thiab tshwj xeeb tshaj yog haum rau siab - qhov kub thiab txias ntawm 900℃mus rau 1100℃.
