Webinar Overview

Everyone knows that stainless steel resists corrosion, but beyond that, an amazing range of half-truths and exaggerations have evolved - often misleading and sometimes simply wrong.

This webinar looks at some of the more popular myths, explains why they are wrong, and more to the point, gives examples of the facts and correct information. Specific misconceptions include:

Extrapolations from prior perceptions
  • There are only two stainless steels: 304 and 316
  • 316 is a marine grade and is suitable for seawater immersion
  • If it has rust stains it is not stainless steel
  • L grade stainless steels are more corrosion resistant than standard carbon grades of stainless steel
  • Stainless steel causes aluminium to corrode
Simply incorrect
  • Only non-magnetic stainless steels have good corrosion resistance
  • All stainless steels have much the same properties including corrosion resistance
  • Low nickel in stainless steel means it will corrode
  • Stainless steel reinforcement will cause accelerated galvanic corrosion of carbon steel reinforcement
  • Foreign grades of stainless steel have different compositions and properties than those used in Australia
  • Cutlery marked 18/10 is better than 18/8
  • Stainless steel can be treated like carbon steel in mechanical designs
  • Well-polished stainless steel does not require maintenance
  • Using a 316 nut on a 304 bolt stops galling of fasteners
Stainless steels are better when you use their advantages
  • Stainless steels are expensive until you look at life cycle costs
  • Stainless steel is different to machine, form and weld
