China made ASTM A537 pressure vessel steel sheet properties

Medium thick steel plate refers to the steel plate with a thickness of not less than 3 mm but less than 20 mm. It can be produced by reversible hot rolling medium and heavy plate mill, and its thin products can also be processed by cold rolling mill. ASTM A537 pressure vessel steel sheet, Medium thick steel plates are mainly used in boilers, shipbuilding, railway cars, automobiles, containers, military industry, national defense, construction, bridges and containers.

The company adopts the ASTM A537 pressure vessel steel sheet international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety ASTM A537 pressure vessel steel sheet management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than ASTM A537 pressure vessel steel sheet. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel ASTM A537 pressure vessel steel sheet is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

Composition characteristics of low alloy structural steel, ASTM A537 pressure vessel steel sheet: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.
