Stainless steel Types and Properties

Specifications define a couple hundred stainless steel grades, differing from one another mainly in chemical composition. Composition is a fundamental characteristic of stainless steel because it determines the alloy’s corrosion resistance, microstructural phase balance, mechanical properties, and physical properties. The … Continue reading
