Common Sense Of Steel Forging Temperature
Publish Time: 2018-05-15 Origin: Site
When forging, the temperature can be roughly estimated according to the color of the steel.
Steel fire color and temperature
Fire color | Temperature（℃） | Fire color | Temperature（℃） |
Dark brown | 520～580 | Bright red | 830～880 |
Palm red | 580～650 | Orange | 880～1050 |
Dark red | 650～750 | Orange yellow | 1050～1150 |
Dark cherry red | 750～780 | Bright yellow | 1150～1250 |
Cherry | 780～800 | White | 1250～1320 |
Bright pink | 800～830 |
The forging temperature range of commonly used steel
Brand | Pre-forging temperature℃ | Finish-forging temperature℃ |
Low-carbon steel | 1250 | 750 |
45 | 1200 | 800 |
T12A | 1150 | 830 |
65Mn | 1200 | 830 |
GCr15 | 1150 | 850 |
Cr12MoV | 1050 | 900 |
W18Cr4V | 1100 | 900 |
Under the premise of ensuring no heating defects, pre-forging temperature should be as high as possible; In the premise of ensuring sufficient plasticity, finish-forging temperature should be set as low as possible.
