Q235B / Q195 / Q345B Hot Rolled Carbon Steel Coils — Product Description
Product Overview
Q235B, Q195, and Q345B hot rolled carbon steel coils are general-purpose structural and low-carbon steel coils produced by hot rolling at temperatures above the recrystallization point. They are supplied in coil form with a mill scale surface, and are widely used in construction, manufacturing, cold forming, and general engineering applications.
These three grades cover the most common requirements in the market: Q195 for excellent cold formability, Q235B for balanced strength and weldability, and Q345B for higher strength structural applications. All grades are available in a wide range of thicknesses and widths, with optional pickling and oiling for surface-critical applications.
Grade Overview
| Grade | Type | Standard | Tensile Strength (MPa) | Yield Strength (MPa) | Key Characteristics |
|---|---|---|---|---|---|
| Q195 | Carbon Structural Steel | GB/T 912 | 315–430 | ≥195 | Excellent cold formability, good weldability |
| Q235B | Carbon Structural Steel | GB/T 912 | 370–500 | ≥235 | Balanced strength & ductility, most widely used |
| Q345B | Low Alloy High Strength Steel | GB/T 1591 | 470–630 | ≥345 | Higher strength, good toughness, weldable |
Note: Q345B corresponds to Q355B under the updated GB/T 1591-2018 standard. Both designations are commonly searched and accepted.
