Never Mess With The Difference In Cold, Warm, And Hot Forging And Here's The Reasons Why.


While the hot, glowing material is closely associated with the forging method this is not always the case. JAV Forgings & Engineering Private Limited in Faridabad Haryana India discusses the differences between forging at cold, warm, and hot temperatures and how every of these affects the finished product including high quality forgings of Mild Steel, Carbon Steel, Alloy Steel, Stainless Steel, Duplex, Super Duplex, Hastelloy, Monel, Inconel, Die-Steel and Low temperature Carbon Steel. JAV Forgings & Engineering Pvt. Ltd. is India’s leading steel forging manufacturer and supplier of a diverse range of products. Our forging product list includes high quality of Flanges, Tube sheets, Rings and Shafts, Spectacle Blinds, Stub ends, Ring-joint gaskets and Self-reinforced nozzles.

By forging at totally different temperatures there are distinctive benefits that can be achieved while forging working. Forging forming of metals according to temperature can be divided into cold deformation (cold forging), warm deformation (warm forging) and thermal deformation (hot forging).



1) Cold forging: refers to blanks processed below the re-crystallization temperature.

Cold forging is of high dimensional accuracy, good surface roughness, good operating conditions and high production efficiency. Therefore cold forging can replace machining sometimes. Cold forging can build metal reinforcement, improve the strength of parts. So it is applicable to aluminum and plastic parts alloy, copper and alloys, low carbon steel, medium carbon steel, low alloy steel which the deformation resistance is small under room temperature. But when cold plasticity, metal deformation resistance is big, with poor plasticity, and contains accumulation of residual internal stress, needs to be continue deformation after intermediate annealing.



2) Warm forging: forging processed around the re-crystallization temperature.

Warm forging process is to obtain precision forgings. The warm forging can improve the precision quality of forgings, at the same time, do not have the forming force as same as cold forging. Warm forging is applicable to complicated shape of small medium carbon steel precision die forgings.



3) Hot forging: deformation temperature above the re-crystallization temperature.

In the deformation process, softening and work hardening coexist at the same time, but soften can completely overcome the effect of strain hardening, and after deformation, metal will have shaft fine grained organizations such as re-crystallization, this deformation is called thermal deformation. All these processes open die forging, hot die forging, hot rolling, heat shock, hot extrusion, belong to the thermal deformation. This is one of the most widely used types of forging process.
