Q235NH Zauv Hlau yog cov cim hauv qhov uas lub ntsej muag sib xyaw ua ke cov hlau hluav taws xob yog: 0.25-0,5-0.5-0.5, sulpium: los ntawm kev txhais ntawm kev txhais ntawm tooj liab, thiab xws li, silicon, txhuas, lwm yam.
Cov txheej txheem tsim qauv ntawm Q235Nh huab cua feem ntau adopts cov txheej txheem kev noj mov-microoalloal, thiab smelted txias.
Tom qab tapping, ntxiv deoxidizer thiab alloy. Tom qab kev sib cav sib ceg, Molten hlau tau nchuav tam sim ntawd. Cov hlau Molten ntawm Q235Nh yaam huab cua hlau tom qab Argon Tshuab thiab kub kho tau raug pov rau hauv slab los ntawm kev nruam lub tshuab txuas. Vim yog qhov sib ntxiv ntawm cov av hauv ntiaj teb tsawg rau Q235Nh Weathering Hlau, Q235Nhture steel yog huv, thiab cov ntsiab lus ntawm kev suav nrog txo qis.
