introduction

The chemical composition of 13CrMo4-5 seamless steel pipe. The main components of this alloy steel are chromium, molybdenum, manganese, silicon and other alloying elements. The second is strength and hardness. 13CrMo4-5 seamless pipe has a certain yield strength and hardness, which can be adjusted according to specific requirements. The last step is heat treatment. Through appropriate heat treatment process, the performance and organizational structure of 13CrMo4-5 can be improved.
13CrMo4-5 steel pipe has the following main properties: high temperature strength, corrosion resistance, good weldability and excellent toughness. First of all, it can maintain high strength under high temperatures and can withstand high temperature and high pressure working environments. Secondly, the alloy steel pipe has good corrosion resistance and can resist the erosion of corrosive media such as oxidation and sulfide. In addition, 13CrMo4-5 alloy steel pipe has good weldability and is suitable for various welding methods. Finally, this alloy steel has excellent toughness and can maintain good impact toughness under high temperature conditions.
The application fields of 13CrMo4-5 steel pipes are widely used in petrochemical, electric power and boiler pipes and other fields. In the petrochemical industry, it is used to manufacture high-temperature and high-pressure petrochemical equipment, such as reactors, heat exchangers, towers, etc.
