100mm Thick Steel Asme A242 type 2 weathering steel plate Spot

A242 type 2 weathering steel plate product is a low-alloy high-strength steel that adds a small amount of alloying elements to general steel to make it have corrosion resistance in the atmosphere. Weathering steel has 2-8 times the atmospheric corrosion resistance of ordinary carbon steel, and the longer the service time, the better the corrosion resistance. In addition to excellent weather resistance, weathering steel also has excellent mechanical and welding functions.

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel A242 type 2 weathering steel plate products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the A242 type 2 weathering steel plate market and has strong competitiveness.

S355J2 steel plate A242 type 2 weathering steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the A242 type 2 weathering steel plate single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.

After adding a small amount of niobium, vanadium and titanium to A242 type 2 weathering steel plate etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent A242 type 2 weathering steel plate products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the A242 type 2 weathering steel plate technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
