BBN steel a professional cold rolled coils and galvanized steel sheets supplier in China. DC51D+AZ 55% AI-Zn galvanized steel sheet for appliances nominal thickness: 0.22~2.0; width: 700~1300; length of steel plate: 1000~6000; Inside diameter of steel strip: 508mm. It is mainly used for cold forming. With the alloy galvanized coating, the recommended nominal coating weight is 30/30, 40/40, 50/50, 60/60, 75/75, 90/90g/m².

Our alloy steel plate and sheets are mainly used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service.Width: 1000mm to 4500mmThickness : 5mm to 150mmLength: 3000mm to 18000mmImpact tested 52° Ca242 type 1 cold rolled weathering steel coil, Supply Condition: As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement.

The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they a242 type 1 cold rolled weathering steel coil work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel a242 type 1 cold rolled weathering steel coil products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate a242 type 1 cold rolled weathering steel coil EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
