Application Of 4130 & 4140 Pipe & Pipe Fittings

Uses of 4130 Alloy

  • This alloy is used for manufacturing ball and roller bearings.
  • This alloy is also good for manufacturing gears due to their heat treatment property.
  • It is used for rock-crushing machinery and automotive parts.
  • It is used for manufacturing structural parts of aircraft.
  • The main use of this alloy is in the field of resistance welding.
  • It is used for cutter tools such as drills, taps, milling cutters, etc.


Summary

4130 steel alloy is famous for its strength property when it is used for heat treatment. The importance of this steel is in aircraft manufacturing companies and welding purpose. It has features of both chromium and molybdenum steel alloys. 

  • Perforating guns
  • Sand screens
  • Downhole drill motors


The steels used for these applications guarantee high resistance to yield strength and tight dimensional tolerances.

Aircraft quality 4130 steel is a medium carbon, low alloy steel containing 0. 15/0. 25% molybdenum and 0. 80/1. 10% chromium as strengthening agents. With a relatively low carbon content of 0. 28/0. 33%, it offers exceptional weldability. With the proper heat treatment it is also readily machined. Annealing 4130 steel offers excellent ductility. It can also be normalized or otherwise heat treated. 
4130 steel alloy is used primarily in the construction of commercial and military aircraft and ground support systems as well as automotive, race cars, off road, hydraulic tools, and machine tool applications. It is an intermediate strength material. Lighter gauges offer lighter weight but still maintain great strength, making it excellent for auto racing and aerospace. Engineers also use 4130 steel for parts such as pins used to secure a critical assembly. These pins are designed to fail at a specific yield in order to avoid a catastrophic failure, and 4130 steel stands up to this test.
