The cold plasticity of No. 45 steel is generally better than S235JR steel material. 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 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.The principle of stainless steel, the corrosion resistance of stainless steel depends on chromium, it depends on a very thin, solid and fine stable chromium rich oxide film (protective film) formed on its surface, to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the corrosion resistance.S235JR steel materialAfter sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
