AISI 4140 steel tube / pipe with high strength and toughness, hardenability is also good, no significant temper brittleness, quenched and tempered after a high fatigue limit and resistance to multiple shocks, good low temperature impact toughness. AISI 4140 steel tube / pipe suitable for manufacturing a certain strength and toughness of large and medium-sized plastic mold.
AISI 4140 steel tube / pipe Application:
Strength, high hardenability, good toughness, quenching deformation is small, high temperature creep strength and long-term strength. Used for manufacturing higher strength and quenched and tempered section forging, such as locomotive traction with large gears, supercharger transmission gear, pressure vessel gears, rear axle, the load of the connecting rod and spring clip can also be used 2000m below the oil deep-well pipe joints and fishing tools, and can be used for bending machine molds.
