Welding hardox 400 specification steel heat treatment

AISI4140 steel plate is used to make forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, turbocharger transmission gears, pressure vessel gears, rear axles, connecting rods with extremely high loads, and Spring clip. It can also be used for oil deep well drill pipe joints and fishing tools below 2000m, and can be used for molds of bending machines.

20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. HARDOX 400 specification, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.

BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our HARDOX 400 specification office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase HARDOX 400 specification 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.
