4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved machinability,which greatly increases feeds and/or speeds,while also extending tool life without adversley affecting mechanical properties.AISI 4140 Chrome-Molybdenum High Tensile SteelIntroductionChemical CompositionMachiningWeldabilityHeat TreatmentForgingStress RelievingAnnealingNormalizingNitridingAISI 4140 is difficult to weld,but welding can be performed using any of the common welding practices.Welding can be done by preheating the section and ensuring that stress relieving takes place after welding.It is basically recommended that welding of AISI 4140 steel in the hardened and tempered condition should be avoided as it changes the mechanical properties within the weld heat affected zone.Likewise welding in the nitrided,flame or induction hardened condition is not recommended.HoweverSee more on azomEstimated Reading Time 3 minsPublished Jun 28,20124140 Heat Treated Alloy Steel - Diehl Tool Steel,Inc.4140 Heat Treated Alloy Steel.Product Type Precision Ground Flat Stock.4140 Super Brake Die is quality alloy steel supplied in the prehardened condition.Special melting and refining practices are utilized to produce a uniform product with exceptional cleanliness.The material is tested to rigorous tool steel standards to ensure uniformity of

Alloy Round 4140 Cold Finished Heat Treated.4142 CFHT can be used for as wide variety of applications where greater toughness and wear resistance is needed over lower carbon grades.Typical applications include ejectors,back up and support tooling,cams,drill collars,bolts,stubs,couplings,reamer bodies,axles,shafting,piston rods,rams File Size 141KBPage Count 1Images of 4140 or 4140 for Heat treat imagesSAE AISI 4140 Steel Properties,Material Heat Treatment 4 rows 4140 or 41l40 for heat treat#0183; 4140 or 41l40 for heat treat#0183;The 4140 steel suspension component will be heat treated to RC numbers in the low or even mid 40s,which equates to strengths in the 185-210 ksi range.Therefore 4140 offers the potential to create a much stronger part if combined with other similar carbon content chromoly alloys such as other 4140 pieces,or parts made from 4340,etc.
So welding A36 to 4140 can be done with a E7018.For 4145 to 4140 you can use E12018,but keep in mind 4140 may have a tensile strength as low 94 Ksi,in which case E10018 would suffice.You need to know if the material is cold drawn or if it has been heat treated.How to weld AISI 4140 Steel materialweldingAISI 4140 is high-strength medium carbon steel.4140 can be easily welded with the right precautionary steps being applied.Other steels in this category as AISI 4130 and 4340 follow the same welding advice.This article provides a detailed introduction to the AISI 4140 materials,their properties,welding,and PWHT requirements.
The Rockwell scale is a hardness scale based on indentation hardness of a material.The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload.There are different scales,denoted by a single letter,that uRatings 14140 heat treat hole shrinkageJan 06,2015Heat treating 4140 - Practical MachinistFeb 26,2007See more resultsHeat Treating 4140 steel FAQ anvilfire How-to.1) 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering,crown and so on.2) Fully hardened 4140 ranges from 54 to 59 HRC.But it should be tempered for any heavy use.3) Tempering recommendations from the ASM heat treaters guide for 4140-4142 is a minimum of 400 4140 or 41l40 for heat treat#176;F.
