AISI 4130 Steel 25CrMo4 1.7218 708A25 SCM430. ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel, containing nominally 0.28 0.33% Carbon, 0.8 1.1% Chromium and 0.15 0.25% Molybdenum. It is similar to 4140 steel which has a higher carbon level (0.28 0.33%), giving 4130 material improved weldability,
Best Practices for TIG Welding of 4130 Chrome Moly Tubing In General Motorsports and Aerospace Applications. The 4130 grade of chrome moly is a high strength low alloy (HSLA) steel that contains molybdenum (0.15 0.25 percent by weight) and chromium (0.8

Jun 20, 2013 · You have already received some good advice on welding the 4130 steel. You have already stated that you would not weld it without a WPS, but who is to say the WPS provided by someone is valid unless you see the supporting PQR. I have worked with 4130 on more than one occasion and in both cases the material was stress relieved after being welded.
AISI 4130 steel is a low alloy steel that is used in structural designs that may be found in applications such as aircraft engine mounts or welded tubing. It is well known for its ease of welding and ability to harden in commercial applications. It is commonly referred to as chromium molybdenum steel.
Common ways to weld 4130 steel 4130 steel relies on the addition of carbon, as well as molybdenum and chromium, as agents that increase hardenability — the ability to increase hardness and strength through heat treatment. The strength of the material can change greatly depending on its conditionannealed, normalized or quenched and tempered.
Peer review under responsibility of INEGI Institute of Science and Innovation in Mechanical and Industrial Engineering doi10.1016/j.proeng.2015.08.057 ScienceDirect 1st International Conference on Structural Integrity An Analysis of the Mechanical Behavior of AISI 4130 Steel after TIG and Laser welding process.

MIG welding 4130. It's really a stronger filler for medium carbon steels when compared to er702 6 or other low carbon steel filler and this is what makes it able to match the base 4130 a little better along with taking into account the small addition of molybdenum. This
4130 STEEL ROD COLD FINISHED Spec. MIL S 6758A Normalized. Good tough steel that I use to make clam hoes. They hold up pretty well considering that they are used in salt water and mud daily and rarely if ever rinsed off. Paul . November 3, 2018.

The chromium content is approximately 0.8 1.1%. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion carbon content the alloy is excellent from the fusion heat treatment. The actual breakdown of 4130 alloy steel is as followsCarbon 0.28 0.33 Chromium 0.8 1.1 Manganese 0.7 0.9
The ‘Shielding Gas’ Used In The Gas Welding Of 4130 Steel Tubing Is 100% Argon, 15 – 20 Cfh. For The Use Of ‘Backing Gas’ In The Welding Of 4130 Oval Tubes, Applicable Standards / Codes Have To Be Applied, But These Are Not Needed For Nhra Applications. In The Gas Welding Process Of 4130 Square Tubing, There Is No Need For Pre Heat.
The AISI 4130 steel had been also considered, since it is applied in landing gears, small aircrafts engine cradles, and besides general industries. In this work, as a comparative welding process, Laser Beam Welding (LBW) was used as an alternative to the traditional TIG (Tungsten Inert Gas) welding.
AISI 4130 is a chromium molybdenum steel that is in general (aviation) use due to its well established heat treating practices and processing techniques. AISI 4135 has a slightly higher carbon version of AISI 4130. AISI 4140 is a chromium molybdenum steel that can be heat treated to higher strength levels or in thicker sections than AISI 4130.
Dec 07, 2001 · Topic Welding Industry / Technical Discussions / Welding 4130 tube even with using a mild steel filler rod, the weld produced in a thin wall tube rapidly cools by radiation due to lack of material thickness and the rapid cooling near the edge of the weld acts as a quench line and causes a narrow hardened region to be created along side the

Jun 28, 2011 · Made in fair quantities 1060 or 4150 makes sense but both would have a complete heat treat after welding (properties will be above 120ksi yeild). 4130 could be done and stress relieved, 4320, 8620 or 9310 could be done with pre heat only and slow cool. 4150 and 1060 have high CE numbers (carbon equivalent), and need high pre heats for welding.
