75Cr1 alloy tool steel Detailed introduction
75Cr1 is a foreign standard cold working tool steel steel number, often used in the manufacture of small tools, such as: mandrel, punch, ramming tools, razors and so on.
The following common problems may occur in the use of 75Cr1 alloy tool steel
Chemical composition: 0.2 ~ 0.78%C,0.25 ~ 0.50%Si,0.5 ~ 0.8%Mn; 0.3 ~ 0.4%Cr,P≤0.035%,S≤0.035%, is a cold work tool steel,
Recommended annealing temperature: 700 ~ 720℃, hardness after annealing 200HBS, should be a spheroidizing annealing process, the actual production temperature should be adjusted to 720℃ heating!
