xar 400 steel material hot rolled mold plate

The location weld of xar 400 steel material, wear-resistant steel plate is only allowed to be welded on the base metal surface with the electric welding rod for welding the base metal; in the welding of the base course, the base weld shall be strictly prevented from melting to the transition layer or even the multiple layer weld of stainless steel, so as to prevent a small amount of high chromium and high nickel surfacing wear-resistant steel plate components diluted into the carbon steel weld to form martensite structure and harden.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products xar 400 steel material are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

Oxygen is a harmful element in xar 400 steel material steel. With the increase of oxygen content, the strength of xar 400 steel material steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of xar 400 steel material steel.
