Q275 steel plate properties and the usage

Q275 steel plate is a kind of carbon structural steel, with high strength, good plasticity and cutting performance, certain welding performance, small parts can be quenched and strengthened, and it is mostly used to manufacture parts with high requirements, such as gears and shafts. , Sprockets, keys, bolts, nuts, section steel for agricultural machinery, conveyor chains and chain links.

The equivalent material of Q275 steel plate:
Corresponding to Japanese JIS brand: SS490
International Organization for Standardization: E275A
Corresponding to the old brand: A5

The chemical composition of Q275 steel plate (mass fraction) (%)
C: ≤0.24
Mn: ≤1.5
Si: ≤0.35
S: ≤0.050 (Grade A)
P: ≤0.045

Q275 steel plate is mainly used to make more important mechanical components in construction and bridge engineering, which can replace high-quality carbon steel. Q215B is equivalent to No. 10-15. Q235B is equivalent to No. 15-20 steel, Q255B is equivalent to No. 25-30 steel, and Q275B is equivalent. 35-40 steel.
