Q345B UNIVERSAL BEAM 12METERS
Q345B universal beam is a high-quality steel with the advantages of high strength, corrosion resistance, and earthquake resistance. It is one of the indispensable materials in construction and manufacturing.
Q345B UNIVERSAL BEAM 12METERS product details:
① It consists of Q + number + quality grade symbol + deoxidation method symbol. Its steel number is prefixed with "Q", which represents the yield point of the steel. The following number represents the yield point value in MPa. For example, Q235 represents a carbon structural steel with a yield point (σs) of 235MPa.
② If necessary, symbols indicating the quality grade and deoxidation method can be marked after the steel number. The quality grade symbols are A, B, C, D, and E respectively. Deoxidation method symbols: F represents boiling steel; b represents semi-killed steel; Z represents killed steel; TZ represents special killed steel. Killed steel may not be marked with symbols, that is, both Z and TZ may be unmarked. For example, Q235-AF represents Grade A boiling steel.
③Special-purpose carbon steel, such as bridge steel, marine steel, etc., basically uses the representation method of carbon structural steel, but a letter indicating the purpose is appended to the end of the steel number.
