316L ASTM yog dab tsi?
Hlau qib 1.4404 (tseem hu ua ASTM 316 / 316L thiab ≈ SS2348) yog ib qho yooj yim machined stainless "acid-resistant" steel.
316L yog qib stainless hlau cov ntaub ntawv, AISI 316L yog cov qib American, thiab sus 316L yog cov qib Japanese sib xws. kuv lub teb chaws txoj kev sib koom ua ke digital code yog S31603, tus qauv qib yog 022Cr17Ni12Mo2 (tus qauv tshiab), thiab qib qub yog 00Cr17Ni14Mo2, uas txhais tau tias nws tsuas yog muaj Cr, Ni, thiab Mo, thiab cov lej qhia txog feem pua. Lub teb chaws tus qauv yog GB/T 20878-2007 (tam sim no version).
316L stainless hlau seamless yeeb nkab yog ib puag ncig, square, los yog cov khoom siv hlau nrog lub hollow seem thiab tsis muaj seams nyob ib ncig ntawm nws. 316L stainless hlau seamless kav yog tsim los ntawm steel ingots los yog cov khoom tube blanks uas yog perforated rau hauv capillary hlab, thiab ces kub dov, txias dov los yog txias drawn. Stainless hlau seamless kav muaj hollow seem thiab yog dav siv raws li cov kav dej rau conveying kua.
