Q235 is a plain carbon structural steel that is used throughout China. It is also known as Q235A, Q235B, Q235C, and Q235D. Since it is mild steel, it is utilized in production without heat treatment. The Q designates the yield point, and the 235 indicates the yield strength. It has good plasticity and weldability.
As the thickness of the material increases, Q235's yield value decreases. Due to its moderate carbon content, the performance is comprehensive and adequate. Q235 also matches well in strength, welding, and plasticity. Most often, it is rolled into a steel plate, rod, bar, or angle frame. It is most commonly used in the engineering and construction industries.
The Q235 steel material is in accordance with PRC standards. Carbon steel for special projects and purposes, like marine and bridge steel, typically uses carbon structural steel expression. However, the letter indicating intents and purposes is included at the end of steel grade.
