ASTM A312 253MA Seamless Yeeb Nkab
ASTM A312 253MA Seamless Pipe qhia txog ASTM A312 253MA Seamless Pipe tus qauv rau welded Austenitic stainless hlau Seamless yeeb nkab. ASTM A213 TP304 yog austenitic stainless hlau, hom AISI 304 steel, nrog zoo corrosion kuj thiab vuam zog. AISI 2330 yog cov hlau alloy uas muaj zog thiab tawv, nws cov qauv thiab cov khoom tuaj yeem hloov kho los ntawm cov txheej txheem kev kho cua sov sib txawv.
Cov hlau no feem ntau siv hauv aerospace, tsheb, roj thiab roj rho tawm thiab siv los ua cov kav dej, lub tog raj kheej, cov khoom siv dav hlau, cov cav tov thiab lwm yam. Nyob rau hauv cov txheej txheem sib sib zog nqus, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau kev xaiv cov cuab yeej tsim nyog thiab kev txiav tsis zoo, nrog rau cov txheej txheem kev kho cua sov kom tsim nyog los xyuas kom meej tias cov txheej txheem ua tau zoo thiab qhov chaw zoo.
