Q235-B carbon structural steel

Online

Product information

Grade: Q235-B
It consists of Q+ number + quality grade symbol + deoxidation method symbol. Its steel number is preceded by "Q", which represents the yield point of the steel, and the following number indicates the yield point value in MPa. For example, Q235 indicates a carbon structural steel with a yield point (σs) of 235 MPa. ② If necessary, the symbol indicating the quality grade and deoxidation method can be marked behind the steel number. The quality grade symbols are A, B, C and D respectively. Deoxidation method symbol: F stands for boiling steel; b stands for semi-killed steel; Z stands for killed steel; TZ indicates a special kill steel, and the kill steel may not mark the symbol, that is, Z and TZ are not marked. For example, Q235-AF indicates Class A boiling steel.

Product parameter

Chemical composition
‌ carbon (C) ‌ ranges from 0.12% to 0.20%. Carbon is the main strengthening element in steel, which increases the hardness and strength of steel, but also reduces its plasticity and toughness.
‌ manganese (Mn) ‌ ranges from 0.30% to 0.70%. Manganese can improve the strength and hardness of steel, but also help to improve the processing properties of steel.
The content of ‌ silicon (Si) ‌ does not exceed 0.35%. Silicon can increase the strength of steel, but also reduce its plasticity and toughness.
The contents of ‌ sulfur (S) ‌ and ‌ phosphorus (P) ‌ do not exceed 0.045% and 0.045%, respectively. Sulfur and phosphorus are often considered harmful elements in steel because they can cause hot and cold brittleness of steel.
