Webinar Overview

This introductory webinar looks at applications and limitations in the use of stainless steels at temperatures above 200oC. Although stainless is well known for its wet corrosion resistance, the resistance of some grades to elevated temperature attack is less understood. Welding is a very short term excursion, but long term elevations such as fire, exhaust gases, ovens or processing furnaces may also include aggressive chemical mixtures. Mechanical designs must consider changes in strength with temperature and time, the possibility of metallurgical transformations and differential thermal expansion, especially with cyclic operations. And, while chromium is still the primary protection, its form and the other elements that are useful for high temperature alloying are different from low temperature operation.

Topics covered include:
  • Differences between wet and high temperature deterioration
  • Strength vs. temperature for stainless steel and other materials
  • The importance of time of exposure including both creep and unwanted phases
  • Good elements for high temperature corrosion resistance
  • Family temperature limitations for martensitic and precipitation hardening grades compared to ferritic, duplex and austenitic materials
  • Corrodents and their effects in gas, liquid or solid form - frequently as mixtures
  • A brief interlude on higher alloys and ceramic
