One Minute Mentor: Martensitic Stainless Steels

A stainless martensitic alloy should have the following characteristics:
• It must have at least 10.5% chromium to qualify as stainless, and even more for better corrosion resistance.
• It should be fully austenitic at some temperature.
• The temperature at which austenite forms on heating should be sufficiently high to permit tempering above the temper embrittlement range.
