We have completed the re-adjustment of the entire product system and operation system to better provide quality 90 Degree Titanium Elbow Bend pipe, Mould Steel Sheet, 4140 Steel Tube and services. Honesty and efficiency are our service philosophy, and letting customers enjoy our support and considerate service is our ultimate goal. Since its establishment, we have been working hard to create trustworthy products for customers and end users.
4140: The steel is made of alloy steel, which complies with the standard ASTM A29 / A29M-04
This product has high strength and high hardenability. Good toughness, small deformation during quenching, creep strength and long-term strength at high temperature. Used for forgings requiring higher strength and larger quenched and tempered sections than 35CrMo steel. Such as large gears for locomotive traction, supercharger driving this wheel, rear axle, connecting rods and spring clips under heavy load, can also be used for oil deep well drill pipe joints and fishing tools below 2000m
