The most commonly used is the ISO Class 8.8 SAE Grade 5 screw, generally using medium carbon steel, ML35 SAE 1035 DIN 35 JIS SWRCH35K after heat treatment (quenching + tempering), SAE5140 40Cr etc. can also be used, alloying elements increase for heat treatment Hardenability has a great help, so the large size of the screw can choose to use alloy steel, not to use the medium carbon steel to cause we often say that the central part of the "quenchable" phenomenon.
ISO Class 9.8 10.9 SAE Grade 8 uses low-to-medium-alloy steel materials, and after heat treatment (quenching and tempering), the alloy material has a good combination of mechanical properties. The commonly used material is 40Cr 35CrMo SAE5140 SCM435 SAE4135. SAE4137 JIS SCr440 (H) DIN 41Cr4 and so on, in fact, 45 # can also achieve the required mechanical properties, but in terms of comprehensive mechanical properties than the alloy steel slightly inferior.
