Mechanical Property
Q355 steel yog Suav tsis tshua muaj hlau alloy siab zog cov qauv hlau, uas hloov Q345, cov khoom ceev yog 7.85 g / cm3. Raws li GB / T 1591 -2018, Q355 muaj 3 qib zoo: Q355B, Q355C thiab Q355D. "Q" yog thawj tsab ntawv ntawm Suav Pinyin: "qu fu dian", uas txhais tau tias Yield Strength, "355" yog qhov tsawg kawg nkaus tus nqi ntawm yield zog 355 MPa rau steel thickness ≤16mm, thiab tensile zog yog 470-630 Mpa.
