5.FAQ

Q1:What are the differences between A36 carbon steel coil and national standard Q235B steel coil?

A1:The two have similar performance and can be used interchangeably, but there are slight differences: A36 has a yield strength of ≥250MPa and carbon content of ≤0.26%; Q235B has a yield strength of ≥235MPa and carbon content of ≤0.20%. A36 is more suitable for American standard projects, while Q235B is applicable to national standard projects.

Q2:Can A36 carbon steel coil be used in low-temperature environments?

A2:It is not recommended to use it for a long time in low-temperature environments below -20℃. A36 has limited low-temperature toughness and is prone to brittle fracture in low-temperature environments. If low-temperature application is required, it is recommended to choose special low-temperature steel.

Q3:What should be noted in the welding of A36 carbon steel coil?

A3:Before welding, it is necessary to clean impurities such as oil stains and rust on the weld surface; E43 series welding rods can be selected; if high precision is required for components after welding, straightening treatment should be carried out to avoid welding deformation.

Q4:What is the rust resistance of A36 carbon steel coil?

A4:A36 is carbon steel without rust-resistant alloy elements, and is prone to rust in humid environments. It is recommended to carry out surface treatment such as painting, galvanizing and anti-rust oil coating to improve rust resistance.
