When welding 4130 and 4140 steel, holding the weldment at the preheat temperature for some time after welding, followed by covering the weldment in ceramic insulation, is beneficial because this allows the diffusion of hydrogen from the weld metal and the heat-affected zone (HAZ).
4140 Alloy Steel Flat is an cold drawn annealed steel of relatively high hardenability with its chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. 4140 Alloy Steel Flat responds well to heat-treatment and is relatively easy to machine in the annealed condition. 4140 Alloy Steel Flat has good strength and wear resistance
Don''t forget to preheat the 4140 and slow-cool the final weldment, because it is prone to cracking. Without knowing the specific heat treatment of the 4140, I generally recommend a preheat temperature of at least 450 degrees F. This article originally appeared in The WELDER magazine.
4140 is the most commonly used of the high tensile steels with a wide range of appliions in automotive, Gear and Engine construction, Crankshafts, Steering knuckles, Connecting rods, Spindles, Intermediate gears, Pump and Gear shafts.

Steel alloy 4140 cold roll is a popular general-purpose alloy, ideal for parts that require high tensile strength and toughness. It has considerable atmospheric corrosion and wear resistance, and will not become brittle. 4140 has a machining cost factor of 2.9 when compared to steel 12L14. It is not ideal for welding due to its lead content.

A preheat and interpass temperature of 500°F to 700°F is generally sufficient. Exact furnace controlled temperature is not required, a heat crayon will provide adequate guidance. When using a torch, move rapidly and evenly to provide a general increase in temperature. Maintain preheat temperature during weld.
Stainless Steel. Tech Steel & Materials offers stainless steel alloys in a variety of shapes and parts – rod, bar, wire, sheet, plate, strip, coil, tubing, forging and casting – for use in the appliions demanding both the diverse properties of steel.
4140 Pre Hard steel bar. 4-1/2 x 4" Long. This material has a hardness of 28-32 R/C can still be machined with HS cutters, weight is approx 18# Have other sizes available also or can cut to your requirements Please ask.
12/06/2009· 4140 Steel Welding_Help. 06-12-2009, 02:59 PM. We are trying to weld several pieces of 4140 Stell togather without much luck. The welds have to Mag. Particle inspection afterwards, and of the 10 sets that we have welded, 7 of them did not pass the Mag. Particle Inpsection. I tried grinding the welds and rewelding and of those only two of the
4140 is a frequent choice for aircraft tooling mainly because it can be heat treated for much higher hardness than plain steel, and because its more dimensionally stable than cold rolled steel. This particular job was a crows foot that is usually used to fit in tight places when using a torque wrench.

ER70S-6 is also better for creating a smooth transition from the weld to the base metal, also known as wash-in or tie-in. Better wash-in may be a requirement in appliions subject to fatigue. ER70S-6 wire can provide better wetting at the weld toe when compared to an ER70S-3 wire. A quality MIG wire is critical in robotic welding appliions.
04/09/2007· Welding 4140. We are welding 4140 anywhere from 1/2" to 1 1/2" thick (in the heat treated condition). Currently, we are using ER80S-D2 as welding wire and because of positioner rotation speeds, welding short-circuit mode (GMAW). Weld joint design is a V-groove (with backing) CJP. Basics of process follow:
will be decided mainly by the wire diameter, welding speed and weld position. With the SAW process used to perform about 90% of the Alloy 625 weld overlays on this development and an approximate 20,000 lbs of Alloy 625 (ERNiCrMo-3) filler metal being melted the one diameter that emerged as
The heat from welding makes the base material expand during heating and contract when cooling. This creates residual tensile stresses around the weld that can cause cracking or shorten the life of the part. Typically, AISI 4130, 4140, and 4340 require a stress relief after welding …
01/08/2000· Also before on structural appliions of 4140 plate and round bar pins, I buried the parts in warm, dry sand for slow cooling. In another case, repairs on a 4140 crane tip, offshore, in a cold wind, I kept a rosebud on the base metal the whole time during welding, and after I was finshed, I wrapped it with fire blanket to keep the wind off.
08/06/2009· In the mid 1980''s we fabried a prototype high speed track out of C1026 and C1040 and used a .30 carbon weld wire, annealed and heat treated the blocks and none cracked. The C1026 did stretch past yield under load. We have had good success using an E80SD2 welding wire C1045 to 8620. Ed Danzer /p>
4140 can be welded to 4140 with undermatching filler metals such as ER70S-6 or ER80S-D2 (or equivalent flux-cored wires) provide the appliion does not require full strength. If you require complete joint penetration welds then matching filler metal is suggested.
