ASTM A299 GR.A Mn-Si Alloy Siab siab lub nkoj steel phaj

Cov pa roj carbon steel nrog Manganese-Silicon phaj SA299 Qib A, SA299 Qib B raws li tus qauv steel specification ASME SA 299 / SA 299M.Muaj lwm yam ob qib steel A299 Qib A thiab A299 Qib B muaj cov khoom zoo sib xws uas yog raws li ASTM A 299 / A 299M.As rau kev kho cua sov, steel phaj A299 Qib A thiab A299 Qib B sib npaug thiab qis dua 50 millimeter yog ib txwm dov rau hauv cov xwm txheej zoo li dov, lub nkoj siab steel phaj.
Raws li ASTM A299 / A299M tus qauv, steel phaj A299 Qib A thiab A299 Qib B yuav tsum raug xaiv raws li cov txheej txheem hauv qab no: S1.Vacuum kho, S2. Kev tshuaj xyuas cov khoom. S3. Simulated ncej weld kev kho cua sov ntawm mechanical test daim coupons, S4. Kev ntsuas nruj ntxiv, S5. Charpy V-notch impact test, S6. Poob qhov hnyav, S7. Kev ntsuas kub siab ntsuas.
