It is extensively used across numerous industries and is an excellent materials alternative due to its toughness, excessive fatigue strength, and abrasion and impact resistance. Not many grades can match the flexibility and usefulness of 4140. 4140HT Alloy Steel - Alloy Tool Steel Inc.4140HT Alloy Steel has a machinability rating of 50% 10 55% of a 1212 carbon steel. 4140HT Alloy Steel is sold in the pre-hardened condition BHN 262/321 Rc 266/343 with a higher surface hardness and lower center hardness. 4140HT Alloy Steel is capable of meeting ASTM-A322.
Make every attempt to remove material stresses prior to welding, and to ensure that the weld surfaces are clean and free of contaminants, such as grease, dust, oil, etc. After welding, stress relieve at 1000°F to 1250°F, holding at that temperature one hour per inch of greatest cross section. AISI 4140 Alloy Steel (UNS G41400)AISI 4140 alloy steel can be cold worked using conventional methods in the annealed condition. Annealing AISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace. Tempering AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of Acceptable filler metal - American Welding SocietyNov 06, 2010 · 4140 is a chrome moly steel with 0.4% carbon. If you are attempting to develop a weld that has the same strength as the base metal, you need to match the filler metal with the chemistry of the base metal or nearly so. A ER90S-B2 would be a good starting point for GMAW or GTAW. An E9018-B2 would be a good start if you are using SMAW.

MeltingTogether is a supplier of part & tools and offers overhaul consultancy and support to Tata Steel, Aperam, Arcelor Mittal, Greif and Mauser, among others. ER409NB - Weld WireWeld WireER409Nb is a ferritic stainless steel welding wire which is used to weld Type 409 and 409Ti base materials. Addition of columbium leads to a preferential reaction with carbon, saving chromium from forming carbides. This improves corrosion resistance, increases strength at high temperatures.
Jun 19, 2018 · AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. Not many grades can match the versatility and usefulness of 4140. MetalsDepot® - 4140 Alloy Steel Round Bar4140 Alloy Steel Round, 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 Round responds well to heat-treatment and is relatively easy to machine in the annealed condition. 4140 Alloy Steel Round has good strength and wear SAE 4140 round bar,SAE 4140 forging,SAE 4140 sheet,SAE We can manufacture and sales SAE 4140 round bar,SAE 4140 forging,SAE 4140 sheet,SAE 4140 coil,SAE 4140 flat bar,SAE 4140 pipe,Lrregular,Through the eu the authentication, the international ISO certification, military quality, China's largest steel suppliers, perennial inventory quantities stock, welcome the global procurement.
AISI SAE 4140 alloy steel can be made into round steel bar, flat & square steel bar, steel plate, steel tube, and has many uses in the aerospace, oil and gas and automotive industries, typical uses are thin-walled pressure vessels, forged gears and shafts (Motor shafts, pump shafts, hydraulic shafts, etc.), spindles (lathe spindles, milling spindles, etc.), collars, clamps, high strength bolts, valve bonnet, WELDING PROCEDURE SPECIFICATION (WPS) FOR - CSA W47.1-Certification of Companies for Fusion Welding of Steel - AWS D1.6/D1.6M-Structural Welding Code, Stainless Steel Note:CSA W59-18 Welded Steel Construction (Metal Arc Welding) may be referenced when joining stainless steel to carbon steel. This WPS will be presented to the Canadian Welding Bureau (CWB) along with the related WPDS Welding 4140Welding 4140 is a lot like welding 4130 which is a lot like welding plain old steel. Except for being more crack sensitive and therefore needing a preheat before welding on certain applications, the puddle looks very much the same as welding plain carbon steel thats because the composition is so similar. 4130 and 4140 are low alloy steels.
Additionally, 4140 steel is highly ductile when annealed, though it requires more pressure as it is tougher than most carbon steels. 4140 is easily welded, but if this is done after hardening, it will also require a post weld heat treatment.SAE 4140 - Mild Steel TIG Welding Rod - 1lb. Pack SAE 4140 Nov 11, 2019 · SAE4140 is a low alloy, metal-cored (not copper coated) wire designed for the welding of heat-treatable, low alloy steels such as the SAE / AISI 4100 series where higher carbon grades are used or where greater tensile strengths are required. 4140 is a metal cored wire designed for welding and build up on mild & low alloy steels having a smooth stable arc transfer, spatter free, excellent bead
