What is 4130 Steel? AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard. 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 AISI 4130 Steel 25CrMo4 1.7218 708A25 SCM430 What is 4130 Steel?

How To Weld 4140 Steel WELDING ANSWERSThe filler metal recommended for welding 4140 steel is ER80S-D2. ER70S-2 can be used but you will be undermatching the base material. Low-hydrogen electrodes minimize the amount of diffusible hydrogen in the weld. With the elevated carbon content even low levels of hydrogen can wreck havoc.

Generally referred to as chrome-moly, this HTLA is used largely for aviation, racing and welded tube structure applications. MIG Welding 4130 to Mild Steel???? - Weld Talk Message know you cannot weld 4130 to mild steel. The main reason is that when you mig 4130 it superheats it and cools too fast and you get micro cracks that will get detected in the inspection process. Plus of course if you do have an unfortunate accident it will shear the chome moly off the mild steel and be more useless than tinfoil.

    MIG welding 4130 - Miller Welding Discussion Forums

    One of the main reasons the 4130 is mainly tig welded and most experts agree, the transfer of a mig weld to 4130 is more harsh and quicker than a tig weld. The "short arc" transfer with 4130 creates a possibility of more embritlement along the weld. With tig, the basemetal is heated first and already at a molten state before filler is added. This is not the case with mig as starts are on cold material and the MIG welding 4130? Pirate 4x4May 27, 2007 · ER80-S2 is a higher strength rod, 80,000 psi tensile strength. It is a good choice for welding chrome moly but not for mild steel, as the finished weld will have a significantly higher strength than the mild steel base metal. You will also lose ductility, meaning that fatigue cracking is

    Mig welding 4130 tubing - Welding Tips and Tricks

    I am an EAA Flight Advisor. Mig welding 4130 tubing is not considered proper due to the difficulty of ascertaining proper penetration. Gas welding is an approved technique, as well as Tig. It is generally recommended that all welds be stress relieved. With gas welding, this can be accomplished by heating the tubing adjacent to the welds.
