ASTM A334 Qib 3 yog dab tsi?
Qib 3 yog ntsuas rau kev pabcuam txuas mus ntxiv mus txog li ntawm -101℃(-150℃F). Qhov no tau ua tiav los ntawm 3.18-3.82% npib tsib xee ntxiv, uas hloov pauv qhov hloov pauv mus rau qhov kub thiab txias. Rau qhov kub qis, koj yuav txav mus rau 304L stainless (-270 degree) lossis 9% nickel steel (-196 degree).
Qhov txawv ntawm Qib 3 thiab Qib 6 yog dab tsi?
Qib 6 tsis muaj cov ntsiab lus npib tsib xee (C Tsawg dua lossis sib npaug li 0.30%, Mn 0.29–1.06%) thiab ntsuas rau kwv yees li -70 degree. Qib 3 muaj cov npib tsib xee nruj ntawm 3.18–3.82% thiab ntsuas rau kwv yees li -101 degree. Qib 6 muaj ntau dua nyob rau hauv kev lag luam; Qib 3 tau teev tseg thaum tus qauv tsim kub qis dua Qib 6 lub peev xwm tab sis siab dua qhov pib qhov twg stainless hlau yuav tsum tau.
Qib 3 puas tuaj yeem welded?
Yog lawm. Qib 3 welds zoo nrog cov txheej txheem carbon steel vuam (GTAW/TIG, GMAW/MIG, SMAW/stick). Siv qis-hydrogen electrodes (E7018 lossis E8018 kom muaj zog dua) thiab ua ntej yog tias qhov ntsuas kub ib puag ncig qis dua 5℃.
A334 Qib 3 tus nqi piv rau Qib 6 li cas?
Qib 3 raug nqi ntau dua Qib 6 feem ntau vim yog cov ntsiab lus nickel (3.18–3.82% Ni). Nyob ntawm tus nqi npib tsib xee hauv kev lag luam hlau, Qib 3 tuaj yeem raug nqi 20-40% ntau dua li Qib 6 ib 'meter'.
