Description
Stainless Steel Round Bars Manufacturers in India – Stainless Steel Round Bars in Black & Bright Finishes!
Asiamet is one of the biggest manufacturers and producers for stainless steel round bars in 200, 300 and 400 series. We can supply various sizes of stainless steel round bars at the most competitive prices in the industry. Stainless steel round bars supplied by Asiamet, are widely used in many industries. Finishes on stainless steel round bars can vary and include cold drawn, centerless ground, smooth turned, rough turned, turned ground and polished, and HRAP.
Due to its anti-corrosive properties, stainless steel round bars have become essential in the manufacturing of parts for the medical, tooling, mechanical, engineering and food industries.
- 303 stainless steel round bars- has good corrosion resistance, free machining, not suitable for welding or forming.
- 304 stainless steel round bars – has good corrosion resistance, suitable for forming and welding, average machining.
- 316 stainless steel round bars – Is our highest grade and has excellent corrosion resistance, is suitable for forming and welding, but is a little harder to machine
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.

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 304 Grade
Grade |
Another possible grades to 304 Stainless Steel Plates |
301L |
A higher work hardening rate grade is required for cerrtain rool formed or stretch formed component |
302HQ |
Lower work harding rate is needed for cold forging of screws, bolts and rivets |
303 |
Higher mechnaibilty needed, and the lower corrosion resistanc, formabilty and weldability are accaptable |
316 |
Higher resistance to pitting and crevice corrosion is required, in chloride environments. |
321 |
Better resistance to temperatures of around 600-900°C is needed…321 has higher hot strenghth. |
3CR12 |
A lower cost is required, and the reduced corrrosion resistance and resulting discolouration are accceptable. |
430 |
A lower case is required, and the reduced corrosion resistance and fabrication characteristic are acceptable. |
