No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than API 5L X65 PSL2 pipeline steel plate. 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 API 5L X65 PSL2 pipeline steel plate 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.
12Cr2Mo1R steel plate is a kind of Cr-Mo alloy steel, which is a widely used heat-strength steel and hydrogen-resistant steel. As alloy elements such as Cr and Mo are added to low carbon steel, the comprehensive properties of the steel API 5L X65 PSL2 pipeline steel plate are greatly improved, such as good high temperature mechanical properties, high temperature oxidation resistance, corrosion resistance, good toughness, process performance and weldability.
