Steel coupling; Machinability of 4140 Alloy Steel. 4140 alloy steel hex bar is readily machinable. Simple shapes are easily machined following a normalizing treatment while more complex shapes may require annealing. This steel grades carbon level may require a structure of coarse lamellar pearlite to coarse spheroidite for optimum machinability. 4140 Steel Welding_Help - Miller Welding Discussion Forums4140 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 grade 4140 4142 steel Grinding 4140 Steel | 4150 Steel | B7 | Associated Steel CorporationKROMITE ECONO-FINISH [4140/4142 (modified) Heat Treated, Decarb-Free, Pre-Machined Alloy] This alloy plate product is 100% decarb-free and blanchard ground top and bottom (+.015/+.035 oversize) for final clean-up. Typical hardness is Rockwell C 28/34. All products are saw cut from plate with stock allowance.

4140 If you can source it from scrap and arent purchasing it or the grinding belts/media than go for it. In truth it's not an great blade steel as it has an lower carbon content. Perhaps the best method to get an passible blade edge is: 1. Anneal your scrap 2. Cut and grind to desired shape and grind in the bevels. 3. 4140/4142 Steel | Precision Ground Bars4140/4142 alloy steels possess high tensile and yield strength generally hardened and tempered in the range of 850 to 1000 Mpa for an improved machinability. We stock 4140/4142 Alloy Steel Barswhich are cold finished annealed chromium-molybdenum alloy steel. 4142 H.T. Tool Steel | Diamond Metals Distribution4142 material is prehardened from the mill to a hardness of BHN 270/320 in thicknesses to 4" inclusive and BHN 260/310 in thicknesses over 4" to under 6" inclusive. CAUTION: 4142 material must be annealed prior to rehardening treatment to obtain a higher hardness. Heat treat the same as 4140.

Alloy 4140 (AISI 4140) is one of the most popular direct hardening Cr-Mo alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. 430 Stainless Steel | Precision Ground Bars430 stainless steel grade has the capability of resisting oxidation that is up to 870 oC (1598 oF) when used at irregular intervals and up to 815 oC (1499 oF) when used continuously. There is tendency of becoming brittle when put at room temperature, and especially when heated over a long period of time in the range of 400 600 oC (752 grade 4140 4142 steel Grinding Grade 4140 4142 Steel Grinding - Image ResultsItem: 66799 Shape: Round Temper: 3 IN X 1.75 IN ID, .625 IN Wall, Round 4140-4142 ALLOY Hot Finished Seamless, Annealed, SPEC M145, 204.0000-288.0000 IN Length

The material may be further processed by centerless grinding or by cold drawing. Below are some of the ASTM A193 grades used commonly by Atlanta Rod. See Also: ASTM A194 Nuts. Common ASTM A193 grades used by Atlanta Rod: ASTM A193 B7 Alloy steel, AISI 4140 or 4142, quenched and tempered Alloy > 4140 | Peerless SteelThis medium carbon alloy steel grade is widely used for many applications requiring high tensile strength and ductility combined with hardness in the R/C 40 range. The cold finished 4140 alloy steel bars are calcium treated; this addition greatly increases cutting speeds and tool life without sacrificing mechanical properties.
