Q550D Hsla Steel
Kev sawv cev ntawm Q550D siab zog alloy steel: Q "yog thawj tsab ntawv ntawm Suav pinyin rau cov khoom siv zog ntawm cov hlau; "550" yog cov txiaj ntsig muaj zog hauv MPa; D-qib zoo yog qib D (qib zoo tau muab faib ua C , D, E qib).
Thaum Q550D hsla steel phaj yuav tsum muaj cov thickness kev ua tau zoo, ib lub cim sawv cev rau cov thickness kev taw qhia (Z kev taw qhia) qib kev ua tau zoo yuav raug ntxiv tom qab qib predetermined, xws li Q550D-Z15 hsla steel ntawv.
Q550D siab zog qis alloy steel phaj yog tsuas yog siv rau qhov tseem ceeb (tsis tshua muaj kub) siab zog structural qhov chaw, engineering machinery, mining thiab lwm yam steel qauv.
