What tests need to go through in the SA588 grade B carbon steel plate sheet production process

Our company was founded in 2000, which initially committed to providing high-quality steel SA588 grade B carbon steel plate sheet products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export SA588 grade B carbon steel plate sheet steel to the international market, opening up the international steel market.

The types of carbon steel are basically as the following: SA588 grade B carbon steel plate sheet, Carbon structural steel, which is mainly used in various projects. High-quality carbon structural steel, whose main purpose is for important parts. Carbon tool steel, which is mainly used to make various small tools. Cast carbon steel parts for general engineering, which are mainly used for complex parts that are difficult to form by forging and other methods and require high mechanical properties.

Pressure vessel plates SA588 grade B carbon steel plate sheet are used to manufacture pressure vessel equipment in petrochemical, gas separation and gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The general heat treatment of Q345R plate is hot rolling, controlled rolling, normalizing. The impact temperature is normal temperature, 0 ° C, -20.

SA588 grade B carbon steel plate sheet, Q390B steel plate generally adopts the process route of refined material entering the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and controlled cooling. During smelting, The scrap steel is added to the furnace along with the charge and smelted according to the conventional process. After tapping, the deoxidizer and alloy are added. After the molten steel is treated by argon blowing, it is cast immediately. Rare earth elements are added to the steel, the Q390B steel plate is purified, and the content of inclusions is greatly reduced.

SA588 grade B carbon steel plate sheet, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.

our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than SA588 grade B carbon steel plate sheet 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
