ASTM A312 Stainless hlau yeeb nkab
Tso lus
ASTM A312 yog dab tsi?
ASTM A312 yog tus qauv tsim los ntawm American Society for Testing and Materials (ASTM) uas tshwj xeeb hais txog kev tsim khoom thiab cov khoom siv ntawm austenitic stainless hlau seamless thiab welded yeeb nkab.
Tus txheej txheem siv rau cov kav dej nyob rau hauv txoj kab uas hla ntawm 1/8 nti (6.4mm) mus rau 30 nti (760mm) thiab nyob rau hauv thicknesses xws li tus qauv (SCH 5S) rau daim ntawv XXS (SCH XXS).

ASTM A312 Kev kho cua sov
Tag nrho cov kav dej yuav tsum tau muab tso rau hauv qhov kev kho cua sov raws li qhov yuav tsum tau ua kom sov-kho qhov kub thiab txias, cov kav dej yuav tsum tau quenched ib leeg hauv dej los yog txias txias los ntawm lwm txoj kev (ncaj quenched).
Cov yeeb nkab yuav tsum tsis muaj nplai thiab kis kab mob exogenous hlau. Pickling, blasting, los yog nto tiav tsis tas yuav tsum tau thaum lub yeeb nkab yog ci ntsa iab annealed.
