The steel plates for SA302GrC boilers must withstand different pressures and strengths due to the manufactured containers. Generally, the normal pressure is 314MPa or higher, and the working temperature is often between -20°C and 450°C. According to the working conditions and processing requirements of the vessel, the steel plate must have good cold bending and welding performance, good plasticity and toughness, and high temperature short-term strength or long-term strength performance.
The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, ASTM A572 ms steel coil professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better ASTM A572 ms steel coil tomorrow!
ASTM A572 ms steel coil annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of ASTM A572 ms steel coil annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. ASTM A572 ms steel coil annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
Our strutural steel plates are not attacked easily by the chemicals in harsh weather. They are a hard, strong, and durable product. Their characteristics are tested through tests. We perform hardness, pmi, micro, chemical, mechanical, macro, ultrasonic test and more. We pack carbon steel plates, ASTM A572 ms steel coil, hot rolled plates, structural steel sheets safely to maintain their good performance so that they serve longer than usual.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, ASTM A572 ms steel coil sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
