ASTM A387 Qib 11 Chav Kawm 2 yog dab tsi?
Nws yog chromium-molybdenum alloy steel phaj uas tau teev tseg los ntawm ASTM A387/A387M, tsim los rau siab - kub, siab -siab siab- cov khoom siv bearing, nrog zoo heev tiv thaiv hydrogen corrosion, sulfide kev nyuaj siab tawg thiab creep deformation.
Kev kho cua sov dab tsi yuav tsum tau ua rau A387 Qib 11 CL 2?
Nws yog muab tom qab normalizing + tempering (los yog normalizing + ceev txias + tempering), nrog ib tug tsawg kawg nkaus tempering kub ntawm 620 degree, los txhim kho nws txhua yam muaj zog thiab toughness.
