Cov ntsiab lus ntawm A333 Gr6:
- C yam
C lub hauv paus tuaj yeem yog cov tshuaj tov hauv cov hlau los tsim cov khoom sib xyaw ua ke, qhov sib txawv ntawm cov pa roj carbon atoms hauv cov txheej txheem kev kho cua sov lossis kev tsis ncaj ncees ntawm kev tsim thiab faib cov carbide thiab cov khoom steel muaj qhov cuam tshuam tseem ceeb. Carbide yog ib theem nyuaj, tuaj yeem txhim kho lub zog, hardness thiab hnav tsis kam ntawm cov hlau, tab sis tsis tsim nyog rau kev txhim kho steel toughness, yuav tsum tau sim txo cov ntsiab lus carbon;
- Si, Mn keeb Si yog cov txheej txheem steel smelting thiaj li yuav tshem tawm cov pa oxygen hauv cov hlau, Si pab txhim kho qhov kub-kub deoxidation ntawm hlau nrog rau acid-etching kuj; Mn yog ib qho kev txhawb zog uas tuaj yeem txhim kho cov tawv tawv ntawm cov hlau, hnav-tiv taus cov khoom thiab thim rov qab ntawm austenite stability, tab sis Mn yog ib qho yooj yim los tsim MnS sib tov nrog S ntawm kev ua tau zoo ntawm cov hlau kom coj tau lub zog tsis zoo;
- S, P cov ntsiab lus los ntawm cov ntsiab lus ntawm qhov kub thiab txias, feem ntau ntseeg tau tias C, Si, P, S, N, thiab lwm yam yog cov khoom tsim kev puas tsuaj, thiab P yog qhov teeb meem tshaj plaws, thiab Mn, Ni, thiab lwm yam yog cov khoom muaj txiaj ntsig. Yog li ntawd, ASTM A 333/A333M-2013 feem ntau yog tso siab rau Mn los txhim kho qhov ua haujlwm kub qis ntawm Gr6, tswj nruj ntawm S, P cov ntsiab lus.
- Ni lub caij Ni yog cov khoom siv alloying uas txhawb kev ruaj khov ntawm austenite, uas yog qhov tsim nyog rau kev txhim kho cov yas yas thiab lub zog, thiab tib lub sijhawm txo qhov kev hloov pauv kub ntawm cov hlau, thiab cov nickel-nplua nuj thim rov qab austenite tuaj yeem ua tau. khaws cia thiab ruaj khov ntawm qhov kub thiab txias, uas muaj qhov cuam tshuam tseem ceeb ntawm kev txhim kho qhov kub thiab txias toughness ntawm A333Gr6. 2016 version ntawm tom qab version ntawm A333GR.6 ntxiv txhim kho nws cov khoom kub qis nrog kev pab los ntawm cov tshiab ntxiv ntawm Ni nrog rau cov nyhuv alloying ntawm V, Nb thiab lwm yam. ntxiv txhim kho nws cov khoom qis-kub.
