Stainless Steel is Ferric Which Contains more than 12 % of chromium to keep from stain and rust.
And it is an alloy steel of complex which consists of carbon, nickel,silicon,and molybdenum according to its own necessity .
Kinds of Stainless Steel:**
1- Austenite Stainless Steel
This is an alloy steel of Ferrum-Nickel.
Major one is 18 CR-8NI which is non-magnetic at normal and high temperature.
2- Ferrite Stainless Steel
This is an alloy steel of ferrum and chromium same as martensitic type .
It dosen”t make R type in high temperature because it contains 18% Chromium.
3- Martensite stainless steel
This is alloy steel Ferrum and Chromium containing 13% Chromium.
Various mechanical properties can be obtained with proper heat treatment.
Characteristics of Stainless Steel :**
- Fine Surface with bright finish.
- Various methods for surface treatment.
- Abrasion resistant.
- Superior breaking strength.
- Strong against fire and high temperature.
