Q235A flange

Q235A flange， Q235 ordinary carbon structural steel - ordinary plate is a material of steel. Q represents the yield of this material, and the following 235 refers to the yield value of this material, which is around 235. And it will decrease in yield value as the thickness of the material increases. Q235A，Q235B，Q235C，Q235D。 This is a distinction of levels, representing mainly different temperatures of impact!

Q235A grade contains C0.14~0.22% Mn0.30~0.65 Si ≤ 0.30 S ≤ 0.050 P ≤ 0.045

Mechanical properties of Q235: In the sheet metal, it is an ordinary material belonging to the common board series, formerly known as A3.

Execution standard: The external standard is GB709, and the internal standard is GB3274-88
