P355GH steel yield, P355GH steel plate, P355GH chemical

P355GH steel plate under EN 10028-2 standard, and it is a kind of boiler steel. P355GH steel has an appropriate quench-hardening ability, after the suitable metal heat treatment, the microstructure of the body is the uniform sorbite ,bainite or superfine pearlite, thus it has the high tensile strength. More information about our P355GH steel, please see the following:

P355GH steel plate application:

P355GH steel is mainly used for making the carburized parts which don’t have high demand on surface and section size < 50 mm in diameter, such as carburized small gear, small axis, low requirements piston pins, cross pin head, diesel engine sleeve, valve plunger mandril, gearbox joystick, steel bushing, etc of automobiles, tractors and in machine tools production. In addition, in the hot rolling and normalizing state P355GH steel can also be used for manufacturing rivet welding parts, screw and nut etc.

Additional technical services:

Heat treatment (Normalized, TMCP, Quenched and Tempered, N+T), Z-test (Z15, Z25, Z35), Ultrasonic Examination, Low temperature impacting test, DWTT, PWHT and cutting&welding into special pieces for end users. Mill test certificate issued under EN 10204 format.
