Q235 Heavy Plate Cutting

Q stands for the yield of this material. The 235 means the yield value of this material, which is around 235 MPa. And as the thickness of the material increases its yield value decreases. Due to the moderate carbon content, the overall performance is good, and the strength, plasticity and welding properties are well matched, Q235 Heavy Plate Cutting are the most widely used.

The Classification of Q235

Q235 steel plate can be divided into q235a steel plate, q235b steel plate, q235c steel plate and q235d steel plate.

The different levels of Q235, Q235B, Q235C, Q235D, and Q235E represent that the impact temperature is different. A refers to 40 degrees or more, B refers to 20 degrees or more, C refers to 0 degrees or more, D refers to -20 degrees or more, E refers to -40 degrees or more, and the different of A to E refers to the difference in impact temperature in their performance.

Q235A level do not do impact; Q235B level is a normal temperature shock of 20 degrees; Q235C level is 0 degree impact; Q235D level is -20 degree impact; Q235E is -40 degree impact.

Q235 Heavy Plate Cutting Chemical Composition

Q235B grade contain C ≤0.20% Mn ≤1.4% Si ≤0.35% S ≤0.045 P ≤0.045 　　
Q235C grade contain C ≤0.17% Mn ≤1.4% Si ≤0.35% S ≤0.040 P ≤0.040 　　
Q235D grade contain C ≤0.17% Mn ≤1.4% Si ≤0.35% S ≤0.035 P ≤0.035

Q235 Heavy Plate Application

Q235 Heavy Plate Cutting is widely used in construction and engineering structures. Q235 is used to make steel bars or used to build factory house frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., and it is also used in large quantities as mechanical parts that do not require high performance. C, D grade steel can also be used for some professional steel.
