Application:
The alloy seamless pipe is a kind of seamless steel pipe, and its performance is much higher than that of the ordinary
seamless steel pipe. Because the steel pipe contains more Cr, its high temperature resistance, low temperature resistance
and corrosion resistance are better than other seamless steel pipes. So the alloy tube is widely used in petroleum, chemical,
electric power, boiler and other industries.
4140 thick-walled seamless pipe is ultra-high strength steel with high strength and toughness, good hardenability,no obvious
temper brittleness, high fatigue limit and resistance to multiple impacts after quenching and tempering, low temperature Good
impact toughness. The steel is suitable for the manufacture of large and medium-sized plastic molds requiring a certain strength
and toughness.
4140 thick-walled seamless pipe characteristics and scope of application: high strength, high hardenability, good toughness, small
deformation during quenching, high creep strength and long-lasting strength at high temperatures. Forgings requiring higher
strength and larger quenching section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission
gears, rear axles, extremely loaded connecting rods and spring clips, can also be used Oil deep well drill pipe joints and fishing
tools below 2000m, and can be used for molds of bending machines, etc.
