Product Description Hot Rolled Alloy Steel Plate 1.7225 42CrMo4 4140 SCM440 EN191: 42crmo4 steel introduction42crmo4 is a common chromium-molybdenum steel that usually used after quenched and tempered, with high intensity, high hardenability. BS EN 42CrMo4 round steel has better performance than 34CrMo4 steel due to the carbon and chromium content is higher. 42CrMo4 alloy steel has higher strength and hardenability. The 42CrMo4 alloy material also has high fatigue strength and good low-temperature impact toughness. The temper brittleness is not obvious. 2: 42crmo4 Steel equivalentEN 10250Material No.DINASTM A29JIS G4105BS 970-3-1991BS 970-1955AS 1444AFNOR42CrMo41.722538HM4140SCM440708M40EN19A414042CD4 3: D2 steel chemical composition42CrMo4/1.7225CMnSiPSCrMo0.38-0.450.60-0.900.40 max0.035 max0.035 max0.90-1.200.15-0.30 4: D2 steel mechanical properties Size ? mmYield stressRp0.2,N/nn2, min.Ultimate tensile Stress,Rm,N/nn2ElongationA5,%, min.Hardness HBToughnessKV, Joule, min.<407501000-120011295-35535 at 20oC40-95650900-110012265-32535 at 20oC>95550800-9505: D2 steel overviewsSizeRoundDia 10-200mmFlat bar/plateThickness:6mm-500mmWidth:20mm-1000mmHeat treatmentNormalized ; Annealed ; Quenched ; TemperedSurface conditionBlack; Peeled; Polished; Machined; Grinded; Turned; MilledDelivery conditionForged; Hot rolled; Cold drawnTestTensile strength, Yield strength, elongation, area of reduction, impact value, hardness, grain size, ultrasonic test, US inspection, magnetic particle testing, etc. Payment termsT/T;L/CTrade termsFOB; CIF; CFRDelivery time7-15 daysApplicationD2 used for Blanking Dies, Forming Dies, Coining Dies, Slitting Cutters, Heading Tools, Long Punches, Forming Rolls, Edging Rolls, Master Tools, Beading Rolls, Intricate Punches, Extrusion Dies, Drawing Dies, Lamination Dies, Thread Rolling Dies, Shear Blades, Burnishing Tools, Gauges, Knurls, Wear Parts. 7:FAQ of 42CrMo4 Steel:a.Quenched and Tempered (Q+T)Heat 42CrMo4 steel slowly to 880°C;Soak at this temperature then quench in oil;Temper as soon as 42CrMo4 steel reach room temperature (20°C);Heat uniformly to the suitable temperature of 560°C;Withdraw the 42CrMo4 material from the furnace and cool in the air.b. Forging of 42CrMo4 Alloy SteelPreheat 42CrMo4 engineering steel uniformly and slowly;Increase the forging temperature up to 1150-1200°C.Always keep the forging temperature above at least 850°Cc.WeldabilityEngineering steel 42CrMo4 has only limited weldability. Preheating to 200-300°C is strongly recommended; the upper limit should not be exceeded because of risk for deterioration of the chrome layer.Alloy steel 42CrMo4 can be friction welded. However, precautions are necessary so as to limit the formation of undesirable microstructures in the welded zone.d.Application of 42CrMo4 Alloy SteelsEN 42CrMo4 alloy steel is widely used for engineering steel purpose, such as: making various kinds of machinery, automobile, mining spare part, the gearwheel of the engine, the driving gear of supercharger, the connecting rob, the pinchock under the high pressure, parts for power train applications, cold formed fastener components, shafts, gears, drill collars for the oil exploration, etc.FAQ:Q: Where is your company ?A: Our company located in liaocheng , shandong provice of China.Q: Are you trading company or manufacturer?A: we are manufacturer.Q: How long is your delivery time?A: Generally is 7-10 working days of goods in stock, or 20-30 days if goods are not in stock, it is according to quantitiy.Q: Do you provide samples? is it free or extra?A: Yes, we could offer the sample for free charge.but the customers have to pay the sample courier cost.Q:.
