4140 Round Bar

View Hardened 4140 Alloy steel hex bars Size, 42crmo4 rod Manufacturer in India

Alloy steel is used for the production of a wide variety of tubes, bars, pipes, and rods. One such bar is the 4140 Round Bar that is used as connectors between pipes in the middle. They can also be used as plugins in pressure valves to resist pressure. They are demanded in large scale industries and are well known for being leakproof. 4140 alloy steel round bar is a chromium molybdenum alloy steel specification is broadly utilized in the oil and gas industry. Reliant Pipe & Tubes Pvt. Ltd. is Suppliers of High-Strength 4140 Alloy steel rod which offers greeted strength and heat treatment capability as compared to other bars or rods. This is due to the higher content of carbon in it.

However, these 42crmo4 hollow bars display an inferior weldability characteristic. They are usually supplied in tempered and hardened states within a tensile range of 850- 1000 Mpa. 4140 alloy steel flat bar produced by us have increased machinability, which increases the feed and speed. This also improves the life of the tool without affecting its mechanical properties. In case any 4140 alloy steel round bar is prehardened then they can be surface hardened using flame or induction hardening by using nitride. These tight-tolerance hardened 4140 alloy steel bars are widely used in a wide range of applications in different industries.

For Instance SAE 4140 Alloy steel flat bar is used in axle shafts, crankshafts, connection rods, guide rods, forks, gears, collets, chuck bodies, and milling spindles. Moreover, these 4140 Alloy steel square bars are also used in hydraulic shafts, lathe spindles, pinions, pump shafts, rams, torsion bars, sockets, holders, convey pins, and rolls, and ejector pins. The AISI 4140 Alloy steel hex bar is welded using all conventional methods. They display good ductility. However, they require more pressure for forming as compared to other carbon steel due to their toughness. Alloy steel AISI 4140 Bright bar might need a post weld treatment as welding in heat treated conditions might deteriorate its mechanical properties.
