Stainless steel: The role of nickel

In fact, nickel is so important that nickel-containing grades make up 75% of stainless steel production. The best-known of these are Type 304, which has 8% nickel and Type 316, which has 11%. Nickel provides these properties by changing the crystal structure of steel to an austenitic (face-centred cubic crystal) structure at almost all temperatures.
