What Applications are Best for 4140 Alloy? Applications for 4140 include drill collars, kelly bars, bolts, subs, couplings, reamer bodies, rotary table shafting, valves, zinc-die casting dies, hydraulic machinery shafts, precision lead screws and winch shafts, among others.
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. 4140 steel shaft, 4140 steel shaft Suppliers and 2,749 4140 steel shaft products are offered for sale by suppliers on , of which shafts accounts for 13%, machining accounts for 7%, and stainless steel bars accounts for 1%. A wide variety of 4140 steel shaft options are available to you, such as new.
AISI 4140 alloy steel is heated at 845°C (1550°F) followed by quenching in oil. Before hardening, it can be normalized by heating it at 913°C (1675°F) for a long period of time, followed by air cooling. Forging. AISI 4140 alloy steel is forged at 926 to 1205°C (1700 to 2200°F) Hot Working Alloy Round Bar - RyersonRyerson offers a wide range of alloy round bars to meet your needs. We carry 8620, 4140, 4150 and 4150RS and 4340 in bar through 12 and forged bar through 32 in most grades. Applications include shafts, bolts, sprockets/gears, axles and piston
Name:Sae4140 sae4130 Steel Die Forging Precision Motor Shaft Description:The heavy forging:forged ring, shaft, roller, flange, or gear is widely used for various industries For example:Metallurgy, mining, power station and so on. The manufacturing equipment is 185MN or 100MN hydraulic press, the forging ratio >4.5, the technical condition Crankshafts - ForgedThese include 4130, 4140 and 4340 forgings, which have tensile strength ratings of approximately 120,000-125,000 psi and up to 140,000-145,000 psi for 4340. The main differences between these alloys is the amount of chromium, carbon and molybdenum used in their compositions with nickel being added to 4340.
