China 4130 Hot Finished Mechanical Alloy Tubing Manufactured to ASTM A519

4130 Mechanical tubing for High-Stress Application
We supply 4130 tubing available in wide variety of size range and specifications .Precision 4130 seamless Mechanical steel tubing uses including the manufacturer of hydraulic cylinder for heavy equipment. Therefor , you will find applications in aerospace, motorsports, cranes,excavators ,forklift , front loaders , and other high-stress applications like the fossil fulel industry . Especially revevant is that our 4130 tubing is cold drawn and lightweight alternative to carbon steel .
Specifications of 4130 tubing

DIN EN10204-01.05
Typical 4130 Seamless Mechanical Steel tubing Facts:
. Cold working - As a result of its properties , cold working by conventional methods is common with this alloy .
. Annealing- Furthermore, 4130 is annealable at 1550 F for a time long enough to allow thorough heating of the section size . However , it should be cooled in the furnace at a rate of less than 50 F per hour down to 900 F, followed by air cooling from 900 F.
.Tempering - In addition , tempering is possible to restore the ductility that may have been lost after the hardening heat treatment and quench . Alloy 4130 is tempered at between 750 F and 1050 F depending upon strength desired . The lower the tempering temperature the greater the strength .
4130 Characteristics
. Rather low carbon content with provides excellet welding characteristics .
. High yield strength and Tensile Strength
. More responsive to mechanical and heat than carbon steels.
. Is easily machineable with conventional methods
. Also ,Annealing ,forging ,cold and hot working ,and tempering can all be achieved .
