Q235B Carbon Structural steels

Q235B Carbon Structural steels, Q representing yield point of steels, the digital 235, is indicate this material yield point is at least 235 MPa. The yield point will lower according to material's thickness increase. Q235B are been widely used due to the moderate carbon, better comprehensive performance, strength, plastic and better welding performance.
The designation of Q235B Steel consists of a leter standing for the yield point, yielding strength, a symbol for quality grade and a symbol for deoxidation method. Its steel is labeled "Q", which represents the yield point of steel, and the latter figures indicate the yield point value, in units of MPa, for example, Q235, carbon structural steel with a yield stress (σs) of 235 MPa.
If necessary, the steel number can be followed by a symbol indicating the quality level and deoxidation method. Different quality grades of steel: A, B, C, D. Deoxidation method symbol: F representing rimmed steel; b— semi-killed steel; Z— killed steel; TZ—special killed steel; In denomination of designation composition, Z and TZ can be omitted. For example Q235-AF, represent A grade boiling steel.
