  • With these characteristics it is a popular high tensile engineering steel with a tensile of 850°-1000N/mm
  • At low temperatures it has reasonably good impact properties
  • Suitable for a variety of elevated temperature applications
  • For maximum wear and abrasion resistance the steel can be nitrided to give a shallow depth wear resistant case
  • Flame or induction hardening of 708M40T can give a case hardness of 50HRc or higher
