ASC LLP is a trusted Stainless Steel 329 Round Bar Supplier offering high-quality SS 329 rods, forged bars, black bars, and peeled & turned bars in different sizes and specifications for domestic and international requirements.
Stainless Steel 329 Round Bar Overview
Stainless Steel 329 is a duplex stainless steel grade designed to deliver a balanced combination of high mechanical strength and excellent corrosion resistance. Due to its duplex microstructure, this grade provides better resistance against stress corrosion cracking compared to many conventional stainless steel grades.
As an experienced SS 329 Round Bar Manufacturer in India, we supply precision-quality bars manufactured according to international standards. Our stainless steel bars are widely preferred by industries requiring long service life, reliability, and performance under challenging operating conditions.
The presence of chromium, nickel, and molybdenum improves resistance against oxidation, pitting, and chemical corrosion. These properties make Duplex 329 Round Bar suitable for aggressive environments where ordinary stainless steels may fail.
We supply SS 329 bars in multiple forms including:
- Stainless Steel 329 Round Bars
- 329 Stainless Steel Rod
- SS 329 Black Round Bar
- 329 Stainless Steel Forged Bar
- SS 329 Peeled and Turned Bar
- Alloy 329 Bright Bars
- Custom Cut Length Bars

What is UNS S32900 Round Bar?
UNS S32900 Round Bar is a duplex stainless steel product containing approximately equal amounts of ferritic and austenitic phases. This unique structure provides higher tensile strength, excellent toughness, and enhanced resistance against chloride stress corrosion cracking.
Compared to standard stainless steel grades, Alloy 329 offers:
- Higher strength capability
- Better chloride resistance
- Improved fatigue performance
- Excellent weldability
- Longer operational life
Due to these advantages, UNS S32900 bars are commonly selected for marine, chemical, and high-pressure industrial applications.
