4140 Low-Alloy Steel
The steel alloy for industrial applications
The 4140 low alloy is all-purpose steel for industrial applications. It is characterized by its toughness, high fatigue strength, abrasion and impact resistance. 4140 low-alloy steel meets the MPIF 35 standards for structural powder metallurgy parts set by the Metal Powder Industries Federation.
4140. All-purpose &
Heat-treatable Steel
4140 is one of the most versatile low-alloy steels. It is characterized by its toughness, high tensile strength, abrasion and impact resistance. It is a critical all-purpose and heat-treatable steel used extensively in the automotive and oil and gas industries.
Applications
Jigs & Fixtures
Autototive
Bolts & Nuts
Gears
Steel Couplings
Power Steering Joint (DM Production System)
Material: 4140 Low-Alloy Steel
The power steering joint is used for power transfer between an electric power steering motor and the steering shaft in an automobile. 4140 low-alloy steel’s properties such as strength and hardness, are essential for the spline teeth that connect that part to the rest of its assembly.
Full Description
While the production process that uses a conventional press and sinter process would require an expensive mold, the Production System P-50 enables production with no tooling thus reducing lead times and enabling more flexible design for quantities up to 1.2 million per year at a fully burdened part cost as low as $2.45.
Technology/Process
- Single Pass Jetting™ (SPJ) Technology
Linear Pneumatic Piston (DM Production System)
Material: 4140 Low-Alloy Steel
The linear pneumatic piston is used to convert air pressure into rotary motion through a rack and pinion. 3D printed on the Production System with 4140 low-alloy steel, it provides the toughness and wear-resistance required for this application.
Full Description
These parts are traditionally assembled from multiple components due to the geometry and cost limitations of conventional manufacturing processes. The Production System P-50 enables the production of up to 690,000 parts per year at a cost as low as $0.28 per cubic centimetre of sintered 4140 low-alloy steel.
Technology/Process
- Single Pass Jetting™ (SPJ) Technology
Herringbone Gear (DM Production System)
Herringbone gears are found in a wide range of industrial machinery applications. 3D printed with 4140 low-alloy steel, these gears benefit from the excellent hardness of this steel and can be lightweight using complex lattice designs.
Full Description
The lattice designs are possible by additive manufacturing. You can reduce material cost and wear on external components, such as motors and bearings. This type of gear can be mass-produced on the Production System P-50 in quantities up to 200,000 per year with 120 parts nested in each build.
Technology/Process
- Single Pass Jetting™ (SPJ) Technology
Lever Drive (DM Production System)
Material: 4140 Low-Alloy Steel
The lever drive is often used in machine design to linearly adjust the location of components in a machine. Binder jetting easily facilitates features such as the precise grooves critical for locating the correct position of external components.
Full Description
While producing a mid-volume run of 10,000 parts would not be cost-effective with conventional manufacturing given the upfront tooling costs or the labour costs associated with machining, the Production System P-50 can print the required quantities in a day with sintered parts ready in less than a week.
