C-shaped steel is a kind of steel made of cold bending by hot coil plate. C-shaped steel has the advantages of thin wall, light weight, good cross-section performance, etc. Compared with traditional channel steel, the same strength can save 30% of material. Widely used in steel structure building purlins, wall beams, can also be combined into lightweight roof truss, bracket and other building components. In addition, it can also be used for columns, beams and arms in mechanical light industry manufacturing.
Q in Q235 represents the yield limit of this material, and 235 in the back refers to the yield value of this material, which is about 235MPa. And with the increase of the thickness of the material and its yield value is reduced, due to moderate carbon content, better comprehensive performance, strength, plasticity and welding properties are better matched, the most widely used. Mainly used in building and engineering structure. It is used to make steel bars or build plant frames, high-voltage transmission towers, Bridges, vehicles, boilers, containers, ships, etc., and is also widely used as mechanical parts with low performance requirements.
Q235 USE
1. widely used in construction and engineering structures. It is used to make steel bars or build plant frames, high-voltage transmission towers, Bridges, vehicles, boilers, containers, ships, etc., and is also widely used as mechanical parts with low performance requirements. C, D grade steel can also be used for some professional steel.
2. can be used for a variety of mold handles and other unimportant mold parts.
3. the use of Q235 steel punch material, after quenching without tempering directly used, hardness of 36~40HRC, to solve the punch in use of the phenomenon of cracking.
