A612 hlau

Qhov kev qhia tshwj xeeb no npog tua carbon-manganese-silicon steel daim hlau npaj rau welded siab hlab ntsha hauv kev pabcuam ntawm qhov nruab nrab thiab qis dua. Raws li kev xyaum ua cov hlau, cov hlau yuav tsum raug tua thiab yuav tsum ua raws li cov kev cai zoo austenitic grain loj. Cov phaj feem ntau yog muab nkag rau hauv qhov xwm txheej zoo li dov.

A612 steel phaj feem ntau siv thoob plaws hauv kev lag luam roj nrog rau sab hauv thiab sab nrauv, A612 steel phaj kuj tseem siv tau rau kev lag luam petrochemical thiab kev lag luam roj.
