Stainless steel is one of the most widely used and versatile type of steel. Stainless steel is often referred to as ‘corrosion-resistant steel’ – it does not stain, corrode or rust as easily as normal carbon steel. There are more than 60 grades of stainless steel and divided into five families.
In addition to the general side of these metal products, special focus is given to a complete range of stainless steel rods and other bar products. The main benefit of Stainless Steel is its resistance to corrosion, and this is all down to the addition of the Chromium
Due to its anti-corrosive properties, stainless steel square bars have become essential in the manufacturing of parts for the medical, tooling, mechanical, engineering and food industries.

PREN for various Grades of Stainless Steel
What is PREN?
Pitting resistance equivalent numbers (PREN) are a theoretical way of comparing the pitting corrosion resistance of various types of stainless steels, based on their chemical compositions. In general, the higher PREN-value, the more resistant is the stainless steel to localized pitting corrosion by chloride. The elements which have a significant impact are chromium, molybdenum and nitrogen.
The formula used to calculate PREN is as below:
PREN = %Cr + 3.3(%Mo) + 16(%N)
PREN = 1 × %Cr + 3.3 (%Mo + 0.5 × %W) + 16 × %N

Alternative Grades to Stainless Steel Duplex 2205 Grade
| Features |
|
| 303 |
Stainless steel 303 grade can be used when higher machinability is needed, and lower corrosion resistance, formability and weldability are acceptable. |
| 316 |
Stainless steel 316 grade can be used when higher resistance to pitting and crevice corrosion is required, in chloride environments. |
| 321 |
Stainless steel 321 grade can be used when better resistance to temperatures of around 600-900°C is needed. 321 has higher hot strength. |
| 3CR12 |
Stainless steel 3CR12 can be used when lower cost is required, and the reduced corrosion resistance and resulting discoloration are acceptable. |
| 430 |
Stainless steel 430 grade is acceptable when a lower cost is required, and the reduced corrosion resistance and fabrication characteristic are acceptable. |
