For industrial processes, steel alloys are primarily forged in hot conditions. Brass, bronze, copper, precious metals and their alloys are manufactured by cold forging processes; each metal requires a different forging temperature.
Forging of steel
Depending on the forming temperature steel forging can be divided into: Hot forging of steel， Warm forging of steel and Cold forging of steel.
1.Hot forging of steel
Forging temperatures above the recrystallization temperature between 950–1250 °C
? Good formability
? Low forming forces
? Constant tensile strength of the workpieces
2.Warm forging of steel
Forging temperatures between 750–950 °C
? Less or no scaling at the workpiece surface
? Narrower tolerances achievable than in hot forging
? Limited formability and higher forming forces than for hot forging
? Lower forming forces than in cold forming
3.Cold forging of steel
Forging temperatures at room conditions, self-heating up to 150 °C due to the forming energy
? Narrowest tolerances achievable
? No scaling at the workpiece surface
? Increase of strength and decrease of ductility due to strain hardening
? Low formability and high forming forces are necessary
ABOUT KEVA
Keva Casting is a professional casting company that focuses on Construction, Machinery, Automobile, Hardware, Pipeline and many other industries.
We provide top quality products with the best service based on our complete production chain including our own mold design, advanced production techniques, and full management of the supply chain. Keva Casting has two factories located in Zhucheng, China's Shandong province.
We use "shell molding", which is a new technique that has been developed in recent years.This new technique has simplified production procedures and reduced air pollution compared with traditional sand casting and investment casting. Shell making and core making are faster to ensure production in enormous quantities. The dimensions and surface finishing are satisfactory for all kinds of industrial requirements. Besides supplying our own formwork & scaffolding systems, our casting products also supply OEM services in various industries.
