ASTM Cov Yeeb Nkab Yeeb Nkab Specification A 269

Dab tsi yog ASTM A269?

ASTM A269 yog tus qauv kev paub tsim los ntawm Astm thoob ntiaj teb (yav tas los hu ua Austenitic Stainless hlau ntawm kev thov thiab rau cov kev mob siab thiab kub thiab kub. Cov txheej txheem no tsim rau cov kev sib txawv ntawm cov kav dej, suav nrog cov tshuaj muaj pes tsawg leeg, cov khoom siv mechanies thiab cov qauv ntsuas. Siv rau cov yeeb nkab nrog sab hauv lub cheeb thiab nominal phab ntsa tuab ntawm 1/4 hli (6.4 hli) lossis ntau dua, thiab ntau dua li ntawm 0.020 mm) lossis ntau dua.

Dab tsi yog cov khoom sib npaug rau Astm A269?

ASTM A269 thiab nws cov sib npaug raws li ASME, DIN thiab FIN, 304L, 304L, 304L, FACE 254, ALLOT 254, 6MO, 6Moly, unsist S31254, thiab lwm yam.

Qhov sib txawv tseem ceeb ntawm Astm cov qauv

ASTM A269 VS A249

ASTM A249: Yuav tsum tau hais tias Weld tau ua haujlwm txias tom qab vuam thiab ua ntej kev kho cua sov, ntxiv rau kev tswj hwm Weld hlaws dai.

ASTM A269: Tsis tas yuav tsum ua haujlwm txias lossis tswj ntawm Weld hlaws.

ASTM A269 VS A312

ASTM A269: feem ntau yog npog cov yeeb nkab (ob leeg ua tsis tau zoo thiab welded) rau cov kev pab cuam corrosion dav dav thiab cov kev pab kub tsawg.

ASTM A312: Npog Cov Yeeb Nkab (Seamless, Welded, thiab Kev Pab Cuam Tshuam (nrog rau cov kev ntsuas kub thiab cov kev siv ntsuas kub.
