The company has allocated special environmental protection facilities for all P265GH stainless steel pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, p265gh stainless steel steel mill scale, environmental protection dust has reached 100%.

The main applications of normalizing are as follows:① For low carbon steel, p265gh stainless steel. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.

Seamless steel tubes for high-pressure boilers are mainly used in pipes, headers, economizers, superheaters and heat exchangers of high-pressure boilers. The working pressure of seamless steel tubes for high-pressure boilers is generally above 9.8 MPa and the working temperature is between 450℃ and 650℃. The main grades of seamless steel tubes for high pressure boilers are 15CrMoG, 12CR2MOG, 12Cr1MoVG, p265gh stainless steel, etc.. For the seamless steel tubes used for high pressure boilers, their service environment and related properties are also different for different grades.

Our company will accept the product quality objection registration record, pass it to the p265gh stainless steel production unit and relevant departments, and timely coordinate the supervision of product p265gh stainless steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
