Stainless Steels

Description

Stainless steels have emerged as one of the more important man-made materials, designed for strength, corrosion resistance, and easy fabrication. Continued growth in the use of stainless steels provides an incentive to understand their properties, processing, and response to various fabrication rules. This course provides the important facts to help master these alloys for a wide variety of uses.
