Corrosion resistance
Although stainless steel does rust, this only affects the outer few layers of atoms, its chromium content shielding deeper layers from oxidation.
The addition of … See more

Over 150 grades of stainless steel are recognized, of which 15 are the most widely used. Many grading systems are in use, including US SAE steel grades. The Unified Numbering System for Metals and Alloys (UNS) was developed by the ASTM in 1970. Europe … See more

Standard mill finishes can be applied to flat rolled stainless steel directly by the rollers and by mechanical abrasives. Steel is first rolled to size and thickness and then annealed to … See more

The invention of stainless steel followed a series of scientific developments, starting in 1798 when chromium was first shown to the See more

Stainless steel is classified into five main families that are primarily differentiated by their crystalline structure:

Unlike carbon steel, stainless steels do not suffer uniform corrosion when exposed to wet environments. Unprotected carbon steel rusts readily when exposed to a combination of air and moisture. The resulting iron oxide surface layer is porous and fragile. In … See more

A wide range of joining processes are available for stainless steels, though welding is by far the most common.
The ease of welding largely depends on the type of … See more
