STAINLESS STEEL OVERVIEW: TUTORIAL
Stainless Steel: An introduction to a versatile, aesthetically pleasing
and "full life cycle" material.
What is Stainless Steel?
Stainless steel is a family of iron based alloys that must contain at least
10.5% CHROMIUM (Cr). The presence of chromium creates an invisible surface
film that resists oxidation and makes the material "passive" or
corrosion resistant (i.e. "stainless"). This family can be simply
and logically grouped into four (4) branches. Each of these branches has specific
properties and a basic grade or "type." In addition, further alloy
modifications can be made to "tailored" the chemical composition
to meet the needs of different corrosion conditions, temperature ranges, strength
requirements, or to improve weldability, machinability, work hardening and
