Steel Forging | Cold, Warm and Hot Forging

No matter what industry you work in, you will always be looking for the best option on the market, the strongest options and the most durable, and steel forging is a great way to get these qualities in your materials.

Made by compressing a mixture of carbon and iron together at extremely high pressure, steel forging is utilized across many industries, from automotive and agricultural machinery to hand tools and general hardware. Steel forging requires a heating system, and depending on what heat you use depends on the type of forging you are doing. There are three categories of steel forging -hot, warm and cold forged steel. There are advantages to each category, so if you are unsure about what would be best for your business, chat to a professional. 

Hot, Warm and Cold

With hot steel forging, the temperature for forging is between 950 and 1250 degrees Celsius. This create good formability and requires lower forming forces. Warm forging is done between 750 and 950 degrees, has limited formability and needs higher forming forces than hot forging. Lastly, cold forging is done at room temperature and up to 150 degrees, with very low formability and requiring very high forming forces.

The Benefits OF Forged Steel

One of the biggest benefits of steel forging is that through the process the metal becomes stronger than its cast or machined counterparts. The process is designed to create products that very seldom fail, and this is a huge draw card for any company.

Forged steel offers a range of benefits such as a finer grain structure and less surface porosity. It also has a higher tensile strength, greater durability and a better life span than other types of steel.
