Seamless steel tubes for gas cylinder-Seamless steel pipe Price in China ,Manufacturer of Seamless steel tubes for gas cylinder-Seamless steel pipe

This steel has high strength and toughness, high hardenability, critical hardenability diameter in oil 15 ~ 70mm; The steel also has good thermal strength. It has sufficient high temperature strength below 500℃, but its strength decreases significantly at 550℃. When the alloy element is in the lower limit, the welding is quite good, but when it is close to the upper limit, the weldability is medium, and the welding needs to be preheated to more than 175℃ before welding. The steel has good machinability and moderate plasticity during cold deformation. The first kind of temper brittleness occurs in the range of 300 ~ 350℃ during heat treatment. Have a tendency to form white spots.

Seamless steel tubes for gas cylinder Seamless steel pipe function

This steel is usually used in the quenched and tempered state, when the carbon content of the lower limit of steel can also be used as a requirement of higher core strength of carburized steel. In the medium machinery manufacturing industry, it is mainly used for manufacturing large section and tempering parts working under high stress conditions, such as shaft, spindle and high load control wheel, bolt, stud, gear, etc.; In the chemical industry used to manufacture welding parts, plate and pipe welding structure and in the nitrogen-hydrogen medium working temperature does not exceed 250℃ high pressure conduit; Used in steam turbine and boiler manufacturing for fasteners working below 450℃, flanges and nuts subjected to high pressure below 500℃, especially suitable for making conduits working under 300 atmospheres and 400℃.
