Why Stainless Steel?
Corrosion Resistance Mechanical Properties High Temperature Properties Low Temperature Properties Physical Properties Ease of Fabrication Appearance Life Cycle Cost
What makes steel stainless?
Chromium: corrosion & scaling resistance
Carbon: hardness
Nickel: acid corrosion resistance
Molybdenum: pitting corrosion resistance
Sulfur: machinability
Nitrogen, Manganese, Aluminum, Copper, Columbium, Silicon, Titanium, Calcium,
Selenium
