    • IntroductionChemical CompositionMachiningWeldabilityHeat TreatmentForgingNitridingTemperingFlame and Induction HardeningAISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition.The AISI 4140 cold finished annealed chromium-molybdenun alloy sAISI 4340 1.6511 36CrNiMo4 SNCM439 - Waldun SteelAISI 4340 is defined as a heat treatable and low alloy steel which has 0.8% Cr, 0.2% Mo and 1.8% Ni as strengthening alloy elements.Compared with AISI 4140,it has higher strength and toughness,also it has very good fatigue resistance, wear resistance and atmospheric corrosion resistance.AISI 4340 is generally supplied in hardened and tempered condition with the tensile range of 930 - 1080 Mpa

      or the ISS Steel Bar Product Guideline for Bar Steel. 7.1.3 When a steels composition cannot be identied by a standard grade number in accordance with 7.1.1 and 7.1.2, the limits for each required element may be specied using the chemical ranges shown in the table (Heat Analysis Chemical Ranges and Limits of Carbon Steel Bars) of Steel Pipe/Tube - Guangzhou Long Sheng Hing Trading Co China Steel Pipe/Tube catalog of X42 X46 X60 X80 ERW Steel Pipe! Ms Tube, Pipes, Bright Stainless Seamless Round and Square Steel Pipe provided by China manufacturer - Guangzhou Long Sheng Hing Trading Co., Ltd., page8. You simply WILL NOT FIND a better quality crankshaft in We constantly pull samples and run tests on the chemical composition of our 4340 raw steel to make sure it meets every index included in the specifications. The approved raw steel is then forged in a massive 6 story tall 8000 ton (that's 16 Million pounds!) hot die forging press.
