Wholesale Mild Sae 1006 1008 1017 Carbon Steel Plate Carbon Steel Sheet
The main materials used to make carbon steel pipe are Q235, 20 #, 35 #, 45 #, and 16 mn. The main executive standards include national standards, American standards, Japanese standards, etc. The national standards include the standards of the Ministry of Chemical Industry, Sinopec pipe fittings standards, and power pipe fittings standards. Carbon steel pipe is made of steel ingot or solid round steel by piercing and then hot rolling, cold rolling, or cold drawing.
Specification
Chemical composition
Q235 is divided into four levels: A, B, C, D
Mechanical Properties
Q235AQ235B belongs to ordinary low-carbon steel, and Q235C/Q235D belongs to high-quality low-carbon steel.
- Q235A level is not required for impact toughness test,
- Q235B grade is used for impact toughness test at room temperature (20°℃).
- Q235C grade is for 0°℃ impact toughness test,
- Q235D grade is used for the -20℃ impact toughness test.
The impact toughness test uses Charpy ∨-shaped notched specimens. The impact toughness index is AKV.
For the above-mentioned grades B, C, and D steels, they are required to reach AKV≥27J under their respective temperature requirements. Therefore, the four ranks are ranked as A<B<C<D, and Q235D is the best.
Application
Because q235 has good welding performance, good plasticity, toughness, and certain strength, it is often rolled into thin plates, steel bars, welded steel pipes, etc., used in bridges, buildings, and other structures and the manufacture of ordinary screws, nuts, and other parts. And Q235 C and Q235 D grade steel can also be used as some professional steel.
Q235 vs SS400 vs A36
Chinese standard Q235, the tensile strength is 370~500 MPa, and the yield strength is 235MPa.
Japanese standard SS400, the tensile strength is 400~510 MPa, and the yield strength is 245Mpa.
American Standard A36, the tensile strength is 58~80 Ksi (about 400~550MPa), and the yield strength is 36 Ksi (about 250MPa).
Because the mechanical properties of these three grades are similar, they can be replaced within a certain range.
