Q235 ordinary carbon structural steel is also called A3 steel.
Ordinary carbon structural steel - ordinary flat bar is a kind of steel material.
Q represents the yield limit of this material. The following 235 refers to the yield value of this material, which is about 235mpa. The yield value will decrease with the increase of material thickness. Due to moderate carbon content, good comprehensive properties, good combination of strength, plasticity and welding, it is most widely used.
Carbon steel for special purposes, such as bridge steel and marine steel, basically adopts the representation of carbon structural steel, but the letter indicating the purpose is added at the end of the steel grade.
purpose
1. It is widely used in architecture and engineering structures. It is used to make steel bars or build plant room frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. it is also widely used as mechanical parts with low performance requirements. C. Grade D steel can also be used as some professional steel.
2. It can be used for various mold handles and other unimportant mold parts.
3. Q235 steel is used as punch material. It is used directly without tempering after quenching. The hardness is 36 ~ 40HRC, which solves the phenomenon of punch fragmentation in use.
