Aisi 4140 Data Sheet
Eboni Kleifgen
Alloy steels are designated by AISI four-digit numbers and comprise different kinds of steels, each with a composition which exceeds the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va set for carbon steels.
AISI 4140 alloy steel is a chromium-, molybdenum-, and manganese-containing low alloy steel. It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. The following datasheet gives an overview of AISI 4140 alloy steel.
AISI 4140 alloy steel has high ductility. It can be formed using conventional techniques in the annealed condition. It requires more pressure or force for forming because it is tougher than plain carbon steels.
AISI 4140 alloy steel can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat-treated condition, and post-weld heat treatment should be performed.

AISI 4140 Steel Bar, Steel Plate, Flats Supplier, Stockist and Exporter. AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and other applications. Similar to alloy grade AISI 4130 chrome moly alloy steel but with a slightly higher carbon content. The higher carbon content of AISI 4140 steel gives greater strength and heat treatment capabilities in comparison to AISI / ASTM 4130 alloy steels, however it does have inferior weldability characteristics.
ASTM alloy 4140 steel bar, flat or plate material can be used for as wide variety of applications where greater toughness and wear resistance is needed over lower carbon grades. Typical applications for 4140 tool steel uses include Components, Adapters, Arbors,strippers, holder blocks, mold bases, ejectors, back up and support tooling, fixtures, jigs, molds, cams, drill collars, Axle Shafts, Bolts, Crankshafts,stubs, couplings, reamer bodies, axles, shafting, piston rods, rams, hydraulic machinery shafts, gears, sprockets, gear racks, chain links, spindles, tool bodies, tool holders, tie rods, Connection Rods, Chuck Bodies, Collets, Conveyor Pins & Rolls, Ejector Pins, Forks, Gears, Guide Rods, Hydraulic Shafts & Parts,Lathe Spindles, Logging Parts, Milling Spindles, Motor Shafts, Nuts, Pinch Bars, Pinions, Pump Shafts,boring bars,tracks, slides, wear strips or parts, forming dies, brake dies, trim dies, bolsters, machinery parts and components, etc.
Welcome customers to inquiry AISI 4140 steel bar, plate, flat steel for the 4140 steel price. We are professional supplier and exporter for more than 20 years. We offer you worldwide solution for aisi alloy 4140 steel bar.
Osprey 4140 can be heat treated to different material conditions using tempering and is suitable for use in general engineering exposed to heavy strain (shafts, gear, bolts), oil-patch applications, and in heat-treated condition it can be used for wear-resistant applications.
This metal powder is manufactured by Inert Gas Atomization (IGA), producing a powder with a spherical morphology which provides good flow characteristics and high packing density. In addition, the powder has a low oxygen content and low impurity levels, resulting in a metallurgically clean product with enhanced mechanical performance.
Osprey metal powder for Additive Manufacturing is characterized by a spherical morphology and high packing density, which confer good flow properties. For powder bed processes these are essential when applying fresh powder layers to the bed to ensure uniform and consistent part build.
For blown powder processes, such as Direct Energy Deposition (DED), good flow ensures uniform build rates. Tight control of the particle size distribution also helps ensure good flowability. Low oxygen powders result in clean microstructures and low inclusion levels in the finished parts.
Osprey MIM powder has a spherical morphology, resulting in high packing density. This enables the manufacture of feedstocks with high powder loading, which not only minimizes binder costs but also reduces part shrinkage during debinding and sintering. Spherical powder also has excellent flow characteristics, resulting in reduced tool wear and consistent mould filling.
Osprey metal powder for Additive Manufacturing is available in a wide range of particle size distributions that are tailored to the individual Additive Manufacturing systems. They can also be tailored to the particular requirements of the end application, both in terms of mechanical performance and surface finish.
Osprey metal powder for Metal Injection Moulding (MIM) is available in a wide range of particle size distributions, from under 5 μm up to 38 μm. The table shows our standard particle size distributions for MIM powders.
All Osprey metal powders are supplied with a certificate of analysis containing information on the chemical composition and particle size distribution. Information on other powder characteristics is available upon request.
Disclaimer: Data and recommendations are for guidance only, and the suitability of a powder for a specific process or application can be confirmed only when we know the actual conditions. Continuous development may necessitate changes in technical data without notice. This datasheet is only valid for Osprey powder.
AISI 4140 alloy steel round bar sheet plate belongs to medium hardenability steel.AISI 4140 steel has high fatigue strength and low notch sensitivity. Low-temperature impact toughness is also very high, no obvious temper brittleness. AISI 4140 steel round bar is mainly used after quenching and tempering state. it is used to manufacture high-strength parts under impact loads and the fittings with large cross-sections and other stressed members. Such as the horizontal eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, and etc.

2.Great toughness, fatigue strength, abrasion and impact resistance.
3.It is widely be used in the industry due to its excellent versatility and usefulness.
4.The higher carbon content in it, the higher the strength and heat treatment capabilities it is.
5.It can be oil hardened to relatively high hardenability.
Forming
DIN 1.7225 steel has high ductility. It can be formed using conventional techniques in the annealed condition. It is required more pressure or force for forming because it is tougher than plain carbon steels.
