Q275 steel plate

GB/T700 Q275 contains four different steel grades as Q275A,Q275B,Q275C and Q275D.Structural steel Q275D shall be done impacting test at low temperature minus 20 degree centigrade.The equivalent steel grade with Q275D is EN 10025-2 S275J2.
Chemical Composition
Q275 steel plate is a kind of carbon structural steel, high strength, good plasticity and cutting performance, good welding performance, small parts can be quenched and strengthened, mostly used to manufacture parts with high requirements, such as gears and shafts. , sprockets, keys, bolts, nuts, section steels for agricultural machinery, conveyor chains and links.

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

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

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