NC310YW
NC310YW is a high-strength, through-hardening and surface carburizable steel highly resistant to mechanical stress, fatigue stress, and contact friction from extreme force or rotational speeds. In some applications, it may be considered as a suitable alternative to Aermet® 100 or Maraging steels.
