Classification:
Description
Product introduction
Used to manufacture important parts in various machines that are subject to impact, bending and torsion, and high loads, such as steel rolling mill herringbone gears, crankshafts, hammer rods, connecting rods, fasteners, steam turbine engine main shafts, axles, engine transmission parts, Large motor shafts, perforators in petroleum machinery, bolts for boilers with operating temperature below 400 degrees Celsius, nuts below 510 degrees Celsius, seamless thick-walled conduits for high pressure in chemical machinery (temperature 450 to 500 degrees Celsius, no corrosive media ), etc.; It can also be used instead of 40CrNi to manufacture high-load transmission shafts, steam turbine engine rotors, large-section gears, supporting shafts (diameter less than 500MM), etc.; process equipment materials, pipes, welding materials, etc.
Used as important structural parts that work under high loads, such as transmission parts of vehicles and engines; rotors, main shafts, heavy-load transmission shafts of steam turbine generators, and large-section parts.
quivalent material:
35crmo4 under Italy standard.
34crmo4 under NBN standard
2234 under Sweden standard
SCM432/SCRRM3 under JIS standard
