Specifications of Heat & Corrosion Resistant Alloys

Corrosion Resistant Alloys

All Stainless Steels have a remarkable resistance to corrosion, due to the presence of a naturally occurring chromium rich oxide film on the surface.

This film is self repairing in nature in the presence of oxygen and rapidly repairs itself during damage caused by abrasion, cutting or machining.

Due to this remarkable property, a wide range of compositions and many different alloys have been designed, so to exhibit specific properties such as:

1. Intergranular Corrosion Resistance
2. Pitting Resistance
3. Stress Corrosion Resistance

In both oxidising and reducing conditions under cryogenic as well as high temperature applications.

Heat Resistant Alloys

Stainless Steels containing a combination of High Carbon, Chromium, Nickel and a few other specific elements, can be designed to exhibit:

1. Resistance to oxidation (scaling) upto almost 1150^o C
2. Good high temperature strength
3. High Resistance to sigma phase precipitation

Due to their larger grain size and superior creep properties, cast components outperform wrought components and are commonly used as parts of furnaces, radiant tubes, muffle liners and heat treatment trays.
