technical specifications alloy structural steel is generally divided into the quenched and tempered structural steel and surface hardened structural steel.
1.quenched and tempered structural steel such carbon content of steel is generally about 0.25% to 0.55%, and established the structure of the section size, quenching and tempering (quenching and tempering), along the section hardenability, mechanical properties good, if not thoroughly quenched microstructure in the free ferrite, the toughness decreased. A tendency to temper brittleness of steel, such as manganese, chromium steel, nickel chromium steel after tempering rapid cooling. Critical quenching diameter of the type of steel, increasing with the increase of grain size and content of alloying elements, for example, 40Cr, and 35SiMn of steel is about 30 ~ 40mm the while 40CrNiMo, and 30CrNi2MoV steel is about 60 ~~ 100mm, commonly used in manufacture to withstand shaft, connecting rod and other structural parts of a larger load.

2.S355J2WP composition surface hardened structural steel used to manufacture the surface of hard wear and heart of the Ministry of flexible parts such as gears, shafts, and so on. Ministry of parts heart high toughness steel carbon content should be low, generally in the 0.12 to 0.25 percent, at the same time there is an appropriate amount of alloying elements in order to ensure appropriate hardenability. Nitriding of steel needed to join the easy formation of nitrides of alloying elements (such as Al and Cr, Mo). Carburizing or carbonitriding steel permeation by 850 ~ 950 ℃ carburizing or carbonitriding, quenching and tempering at low temperature (about 200 ℃) state to use. Nitride steel nitriding process (480 ~ 580 ℃), the direct use, is no longer handled by quenching and tempering

BEBON steel can supply S355J2WP steel of weathering resistant steel,also can supply other products like:S235J2W steel , S355J0W steel , S355J0WP steel , S355J2G2W steel.
