High precision forged metal parts 4140 Alloy Steel Gear Forging ISO 9001 Certified

High precision forged metal parts 4140 Alloy Steel Gear Forging ISO 9001 Certified


Product Description and Process

Hot Forging Drop Forging Process 4140 Alloy Steel Gear Products Forging Supplier


Production process: metal hot forging process

Machining process: CNC machine, machining center, lathe, mill machine, drill machine, etc.

Surface treatment process: paint coating, electrophoretic coating, electrogalvanizing coating, black oxide coating, powder coating, etc.


Product Material and Uses

Normally produce with low carbon steel, medium carbon steel, low alloy steel, such as 1020 steel, 1035 steel, 1045 steel, 16Mn, Q235, Q345, A105, 20MnMo, 35Crmo, 42CrMo, etc.


The steel forging products are widely used for auto-car parts, truck parts, train parts, vehicle components, construction machinery components, other machinery components, etc.



Forging Advantages and disadvantages

Forging can produce a piece that is stronger than an equivalent cast or machined part. As the metal is shaped during the forging process, its internal grain texture deforms to follow the general shape of the part. As a result, the texture variation is continuous throughout the part, giving rise to a piece with improved strength characteristics. Additionally, forgings can target a lower total cost when compared to a casting or fabrication. Considering all the costs that are involved in a product’s lifecycle from procurement to lead time to rework, and factoring in the costs of scrap, downtime and further quality issues, the long-term benefits of forgings can outweigh the short-term cost-savings that castings or fabrications might offer.

Some metals may be forged cold, but iron and steel are almost always hot forged. Hot forging prevents the work hardening that would result from cold forging, which would increase the difficulty of performing secondary machining operations on the piece. Also, while work hardening may be desirable in some circumstances, other methods of hardening the piece, such as heat treating, are generally more economical and more controllable. Alloys that are amenable to precipitation hardening, such as most aluminum alloys and titanium, can be hot forged, followed by hardening.

Production forging involves significant capital expenditure for machinery, tooling, facilities and personnel. In the case of hot forging, a high-temperature furnace (sometimes referred to as the forge) is required to heat ingots or billets. Owing to the size of the massive forging hammers and presses and the parts they can produce, as well as the dangers inherent in working with hot metal, a special building is frequently required to house the operation. In the case of drop forging operations, provisions must be made to absorb the shock and vibration generated by the hammer. Most forging operations use metal-forming dies, which must be precisely machined and carefully heat-treated to correctly shape the workpiece, as well as to withstand the tremendous forces involved.


Forging Processes

There are many different kinds of forging processes available; however, they can be grouped into three main classes:

Drawn out: length increases, cross-section decreases

Upset: length decreases, cross-section increases

Squeezed in closed compression dies: produces multidirectional flow

Common forging processes include: roll forging, swaging, cogging, open-die forging, impression-die forging, press forging, automatic hot forging and upsetting.


Forging Materials and applications

Forging of steel

Depending on the forming temperature steel forging can be divided into:


A Hot forging of steel

1. Forging temperatures above the recrystallization temperature between 950–1250 °C

2. Good formability

3. Low forming forces

4. Constant tensile strength of the workpieces


B Warm forging of steel

1. Forging temperatures between 750–950 °C

2. Less or no scaling at the workpiece surface

3. Narrower tolerances achievable than in hot forging

4. Limited formability and higher forming forces than for hot forging

5. Lower forming forces than in cold forming


C Cold forging of steel

1. Forging temperatures at room conditions, self-heating up to 150 °C due to the forming energy

2. Narrowest tolerances achievable

3. No scaling at workpiece surface

4. Increase of strength and decrease of ductility due to strain hardening

5. Low formability and high forming forces are necessary

For industrial processes steel alloys are primarily forged in hot condition. Brass, bronze, copper, precious metals and their alloys are manufactured by cold forging processes, while each metal requires a different forging temperature.
