ASTM A672 GR B60 yog dab tsi?
ASTM A672 Gr.B60 steel yeeb nkab belongs rau cov pa roj carbon -manganese steel series, featuring nruj me ntsis tswj cov tshuaj muaj pes tsawg leeg uas ua kom cov khoom homogeneity thiab stability. Nrog ibyield zog ntawm 60 ksi (kwv yees li 414 MPa), cov yeeb nkab no muab lub zog tensile zoo heev thiab elongation, ua rau nws tiv taus siab sab hauv.
Dab tsi yog A672 gr b60 khoom sib npaug
ASTM A672-B60CL22, hom nruab nrab-kub, siab-siab arc-welded steel yeeb nkab, muaj cov khoom zoo ib yam li cov khoom tsim hauv tsev 16Mn low-alloy steel.
