What are the differences between black and painted astm a204 grade b equivalent

The company mainly supplies astm a204 grade b equivalent steel materials, and has a large amount of inventory all year round. We can process and cut all kinds of special-shaped steel parts according to your requirements, and we can arrange fresh production for all kinds of astm a204 grade b equivalent steel materials in customized specifications. The company adheres to the core values of "quality and benefit, integrity and win-win, innovation and efficiency", and provides first-class services. Based on the principle of reputation first, small profits and high sales, we develop the market with high-quality services and flexible business model.

The company mainly supplymild astm a204 grade b equivalent steel plate, alloy steel plate, boiler plate, corten steel plates for railway, marine, automotive, home appliances, shipbuilding, construction, machinery manufacturing and oil tank projects. While accelerating the development of the main steel industry, the company adheres to a diversified development strategy and actively develops the other industry like household products, face mask machine, precision casting producing, steel structures, and heavy plates processing service.

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The astm a204 grade b equivalent metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other astm a204 grade b equivalent alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary astm a204 grade b equivalent carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.

astm a204 grade b equivalent, Q345B steel is high strength low alloy HSLA steel. Due to the addition of alloy elements, the yield strength of Q345B and so on HSLA steel is 25% - 150% higher than that of carbon structural steel with the same carbon content. Using HSLA structural steel instead of carbon structural steel can reduce the self weight of the structure, save metal materials and extend the service life of the structure.

"ASTM A516 Grade 70 plate is a boiler / pressure vessel quality of steel plate for use in low to moderate services. It has improved notch toughness. astm a204 grade b equivalent, A516 Grade 70 steel plates can be produced with thick up to 200mm.For boiler steel plate A516 Grade 70, the yield strength shall be above 260 Mpa, tensile strength from 485 Mpa to 620 Mpa.A516 Garde70 steel plate is equivalent to the P355GH and 490B grades. "

We have our own factory, including the production and manufacturing of steel pipes, with a special astm a204 grade b equivalent steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements.
