How to repair corrosion pits on usage of hardox 400 steel

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of usage of HARDOX 400 steel circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and usage of HARDOX 400 steel management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

S960QL grade is a European standard special alloy structural steel, which belongs to quenched and tempered high yield strength structural steel. S indicates structural steel, 960 is a yield value, in MPa, Q indicates delivery conditions, and L indicates that the impact energy is specified when the temperature is not less than -50℃ The smaller value of. S960QL steel plate is a material in the European standard EN 10025-6.

EN10083-3 42CrMo4 steel plate delivery status: Heat treatment (normalizing, annealing or high temperature tempering) or non-heat treatment delivery status should be specified in the contract. EN10083-3 42CrMo4 steel plate equivalent materials: JIS SCM440, AISI 4140, GB 42CrMo, usage of HARDOX 400 steel etc. EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld usage of HARDOX 400 steel steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for usage of HARDOX 400 steel manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
