din 1.7218 steel plate
This kind of steel is usually used in quenched and tempered state, when the carbon content is the lower limit of the steel is also used as a requirement of carburized steel core strength high. In the medium-sized machinery manufacturing industry is mainly used in the manufacture of large section, at high strain hardening and tempering force work under the conditions of the parts, such as shaft, main shaft and the steering wheel from the high load, bolt, stud bolt, gear and so on; used in the manufacture of high-pressure pipe parts, sheet and tube welding structure and composed of nitrogen and hydrogen containing medium in work the temperature does not exceed 250 DEG C welding in chemical industry; in the steam turbine, boiler manufacturing fasteners for manufacturing, 500 DEG C below 450 DEG C below the flange and the nut by work pressure, especially suitable for the manufacture of 300 atmospheric pressure, working under 400 DEG C to catheter.
