Daim ntawv thov
ASTM A572 GR 50 tus qauv yog dab tsi?
ASTM A572 GR 50 yog lub zog siab qis alloy steel. Qib 50 yog qhov nyuaj rau kev tsim vim nws muaj cov ntsiab lus alloying ntau dua li cov hlau dawb tab sis muaj zog ntau dua rau ib chav tsev ntawm qhov hnyav. Ua tsaug rau nws lub zog siab ASTM A572 Qib 50 Phaj yuav tsum muaj cov khoom siv tsawg dua kom ua tau raws li qhov yuav tsum tau muaj zog dua li cov pa roj carbon monoxide.
Qhov txawv ntawm A36 thiab A572 Gr50 yog dab tsi?
A572 Gr50 muaj qhov yuav tsum tau muaj tsawg dua, kom ntseeg tau tias muaj kev ua tau zoo dua qub -kawg. A36 yog pheej yig dua rau ib phaus, tab sis A572 Gr50 lub zog yuav txhais tau tias koj xav tau cov khoom siv tsawg, uas yuav txo tau tag nrho cov nqi tsim nyog. Ob leeg tau yooj yim welded, tab sis A36 yog me ntsis kev zam txim rau kev tsim khoom
Dab tsi yog qhov txawv ntawm 4140 thiab A572 qib 50 steel?
A572 yog kub -kho cov pa roj carbon steel uas yog siv rau qhov xav tau siab zog rau qhov hnyav piv. Ib qib xws li AISI 4140 muaj kev tiv thaiv corrosion zoo vim muaj cov ntsiab lus chromium thiab molybdenum ntau dua thiab feem ntau siv rau hauv cov phom phom, cov raj roj cua, thiab cov raj xa dej rau yob tawb.
Koj puas tuaj yeem txuas A36 rau A572?
Weldability ntawm ob steels yog tib yam. Welds ntawm ob lub steels (A36 thiab A36 / A572 Gr 50 dual qib) siv tib yam electrodes nuxcs thiab weld- ing tsis ua tau, ~ welded JOints zoo tib yam.
Lub zog kawg ntawm A572 qib 50 steel yog dab tsi?
Teb: ASTM 572 Qib 50 steel muaj lub zog tensile kawg ntawm 450 MPa (metric) thiab 65,300 PSI (Imperial). Nws muaj lub zog tensile tawm ntawm 345 MPa thiab 50,000 PSI.
