Technical Specifications: Closed Die Forging

Closed die forging uses a controlled procedure with a culmination of alloys and heated metals to create the desired shape. Without an appropriate forging die lubricant, effective and economical closed die forging is unattainable. To know more about the technical specifications of this type of forging, please read on.

Mechanical Characteristics of Closed Die Forging

Alloys Used

Closed die forging is a type of forging that has exceptional mechanical characteristics – one of which is adaptability to the different kinds of an alloy such as copper, bronze, and aluminum. Aside from allows, it can also adapt or mold various kinds of steel like stainless steel, tool steel, and alloy steel.

Specifications

When using closed die forging, the tooling division must go through the center of the forging and should not run through the side. The reason for this is that the forging must be detachable from its divisions.

The different cross-sections must be equal to avoid extreme disparities in the flow of the metal. Additionally, a closed die forging uses low and wide rib features. To avoid quick tooling cracks or wear in forgings, manufacturers use large radii. Moreso, an ample and suitable draft angle should be provided wherein compliance of the 5° to 7° for steel and 3° for aluminum are mandatory.

Benefits and Finishing Options

Closed die forging is known for its economical procedure compared with welding assemblies. Other notable benefits include high production speed, use of highly homogeneous steel and alloys, and high rating when it comes to good repeatability. As for the finishing options, closed die forging allows blasting, vibra-polishing, hot-dip galvanizing, and electrolytic zinc plating.

Factors that Guarantee Only the Finest Forging Die

The finished product of a closed die forging is affected by several factors. The most common of which is the accurate process of application of die lubricant at proper intervals. Similarly, the forging result may also be affected by the decrease in friction during the forging procedure. Friction can satisfactorily be decreased by using appropriate polished dies and die lubricants.

Stainless Steel Castings | Common Alloying Elements

If you need stainless steel castings, there are numerous of different metalworking methods that can be done to make your part as specific as possible. One of these specific metallurgical processes is adding alloying elements. Alloying elements can change the structure, corrosion resistance, and mechanical properties of stainless steel castings. Furthermore, every different alloying element effects stainless steel differently. Below we explained the effects of 5 common alloying elements used for stainless steel castings so that you can determine which is best for your next project.

Effects of Alloying Elements on Stainless Steel Castings

1. Manganese: Adding manganese to stainless steel improves hot working properties and boosts toughness, strength, and hardness.

2. Nickel: Nickel can help produce stainless steel castings that are incredibly ductile, corrosion resistant, and tough at both high and low temperatures.

3. Chromium: Stainless steel parts with higher percentages of chromium have a higher resistance to oxidation than parts with lower percentages of this alloying element.

4. Carbon: Carbon, along with iron, is the major alloying element that is used to make stainless steel. It is also used to increase the hardness and strength of the metal.

5. Copper: This alloying element enhances the corrosion resistance and formability of the stainless steel castings. Copper can also be added to decrease work hardening in grades designed for improved machinability.

It’s safe to say that alloying elements can have major effects on stainless steel castings. Now that you know the effects that common alloying elements have on stainless steel, it’s time to determine the best option for your specific needs.
