What is the difference between carbon steel Q235B and A633 Grade A high-strength low-alloy structural steel

BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's A633 Grade A high-strength low-alloy structural steel industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate A633 Grade A high-strength low-alloy structural steel market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

Low carbon steel is a carbon steel with a carbon content of less than 0.25%. Low carbon steel A633 Grade A high-strength low-alloy structural steel is also called soft steel or mild steel because of its low strength and low hardness. Low carbon steel includes most common carbon structural steel and a part of high-quality carbon structural steel, most of which are used for engineering structural parts without heat treatment, and some A633 Grade A high-strength low-alloy structural steel are carburized and other heat treated for mechanical parts that require wear resistance.

Automobile girder steel is a kind of low alloy hot-rolled steel plate with thickness of 2.5-12.0 mm for manufacturing automobile girder (longitudinal beam and cross beam). Due to the complex shape of automobile girder, good stamping performance is required in addition to high strength and cold bending performance for automobile girder steel. The A633 Grade A high-strength low-alloy structural steel, medium thick and heavy steel plates are mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on.

Vanadium is a weak deoxidizer. Adding vanadium into A633 Grade A high-strength low-alloy structural steel steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

ASTM a588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the A633 Grade A high-strength low-alloy structural steel yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 A633 Grade A high-strength low-alloy structural steel has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled A633 Grade A high-strength low-alloy structural steel plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive A633 Grade A high-strength low-alloy structural steel industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
