Talking about the use of Q235 hot plate
Edit:Shenyang Sidi Ou Trading Co., Ltd.   UpDate:2018-08-28

Q in the Q235 hot plate indicates the yield limit of the material, and the latter 235 is the yield value of the material, which is about 235 MPa, and the yield value decreases as the thickness of the material increases. Due to the moderate carbon content, the comprehensive performance is good, the strength, plasticity and welding performance are well matched, and the application is the most extensive.

It consists of Q+number+quality symbol+deoxidation symbol. Its steel crown is “Q” for the yield point of steel, and the latter number indicates the value of the yield point in MPA. For example, the carbon structure with a yield stress (_s) of 235 MPa. The yield point of steel is Q235.

Q235 hot plate (usually rolled) classification: wire or round steel, square steel, flat steel, angle steel, I-beam, channel steel, window frame steel and other sections, steel plates.

Q235 hot plate use:

1. Q235 hot plates are widely used in construction and engineering structures for the manufacture of steel bars or construction plants, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., and are also widely used as mechanical parts with low performance requirements.

2, Q235 hot plate can be used for important parts of grinding tools such as various grinding tool handles.

3. Q235 steel is used as the punch material, and it is directly quenched without tempering. The hardness is 36~40HRC, which solves the problem of the fracture of the punch in use.
