Jun 06, 2014 · The trick is to go with enough carbon to comfortably achieve the hardness level you want. For 45Rc you had better use at least 4140. That will probably solve your problems. If you need higher hardness/strength go to 4150. If you need extra toughness, shock resistance, etc. at high hardness the progression is thru richer alloys like 4340 and 6150. 4340 (E4340) Alloy Steel, AISI 4340, Plate, Round Bar AQ AMS 6415 round bar cold finished or hot rolled steel 4340 is one of the richer alloy steels, featuring hardenability with high strength characteristics. This steel is an excellent choice for highly stressed parts intended to operate under severe conditions. 4340 steel round bar is used for crankshafts, landing gear struts, valves, connecting
Alloy 4340 in Plate SPECIFICATIONS:AISI4340, ASTM A 829 / A6 SAE J404, AMS 2252/ 2301/6359 SAE J404 Castle Metals stocks Alloy 4340 plate through our global distribution network. Our service centers are located throughout the U.S., Canada, Mexico, U.K, France, Singapore, and Shanghai. Customers calling us for 4340 plate a lot of times are frustrated with on-time delivery issues. 4340 High Tensile Steel Interlloy Engineering Steels 4340 hardened and tempered bar can also be successfully nitrided, giving a surface hardness of up to Rc 60. Nitriding is carried out at 490 o C - 530 o. C, followed by slow cooling (no quench) reducing the problem of distortion. Parts can therefore be machined to 4340 Steel 36CrNiMo4 1.6511 EN24 SNCM439 - Otai AISI 4340 steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections. AISI 4340 is also one kind of nickel chromium molybdenum steels. 4340 alloy steel is generally supplied hardened and tempered in the tensile range of 930 - 1080 Mpa. Pre hardened and tempered 4340 steels
