Welding grade St37-2 steel material steel manufacturers

Hot Rolled Plates Products Testing
BBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the St37-2 steel material raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."

Medium and heavy plate is widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields. The surface quality of medium and heavy plate mainly refers to its surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plate. The surface quality of St37-2 steel material, medium and heavy plate not only affects the appearance of the products, but also reduces the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate.

The company has sufficient inventory and complete varieties and specifications. In line with the sales principle of low price operation and quality first, let customers buy St37-2 steel material at ease and use it comfortably! Integrity, professionalism and efficiency are our service tenets. We will wholeheartedly provide excellent St37-2 steel material products and high-quality services for new and old customers. We also sincerely welcome new and old customers to call and write to discuss business and guide work!

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized St37-2 steel material are higher than that of annealed St37-2 steel material, but the elimination of internal stress is not as good as annealing. The normalizing operation of St37-2 steel material is simple, the cost is low, the productivity is high, and it is widely used in actual production.
