Stainless hlau - Qib 316 (UNS S31600)

Qib 316L, qis carbon version ntawm 316 thiab tiv thaiv kab mob los ntawm rhiab heev (grain ciam teb carbide nag lossis daus). Yog li nws tau siv dav hauv cov ntsuas hnyav welded Cheebtsam (tshaj li 6 hli). Qib 316H, nrog rau nws cov ntsiab lus carbon siab dua muaj kev thov ntawm qhov kub siab, zoo li qib 316Ti ruaj khov.

Cov qauv austenitic kuj muab cov qhab nia zoo heev, txawm tias mus rau qhov kub thiab txias.

Cov khoom tseem ceeb

Cov khoom no tau teev tseg rau cov khoom lag luam tiaj tus (phaj, ntawv thiab coil) hauv ASTM A240 / A240M. Zoo sib xws tab sis tsis tas yuav zoo ib yam khoom yog teev rau lwm yam khoom xws li yeeb nkab thiab bar hauv lawv cov specifications.
