Duplex Round Bar

1、Strength and Durability: Offers double the yield strength of conventional austenitic stainless steels, reducing material usage while maintaining structural integrity.
2、Cost-Efficiency: Due to higher strength, smaller diameters or thinner sections can sometimes be used, potentially reducing material costs and weight.
3、Enhanced Corrosion Resistance: Provides high resistance to pitting, crevice corrosion, and stress corrosion cracking, ideal for challenging environments.

Product Introduction

Products Introduction

A duplex round bar is known for its balanced mix of austenitic and ferritic structures, providing a unique combination of strength, corrosion resistance, and weldability. duplex round bars contain about equal parts of austenite and ferrite, delivering better stress corrosion resistance than standard austenitic grades like 304 and 316 while maintaining good formability and durability.

Our Products

applications

Digester Tanks and Components

Digesters are essential in breaking down wood chips into pulp using chemicals and heat. Duplex round bars are used in the construction of digesters, as well as in associated components like nozzles, stirrers, and fasteners, which all face aggressive chemical exposure.

Bleaching Equipment

Bleaching processes expose equipment to chlorine compounds, oxygen, and acidic solutions. Duplex round bars are used in the manufacture of bleach towers, mixers, and pumps, where they resist corrosion and maintain their strength, even in harsh chemical conditions.

Recovery Boilers and Heat Exchangers

Recovery boilers are critical for recovering chemicals and energy from black liquor, a byproduct of pulping. Duplex stainless steel round bars are used in these boilers and heat exchangers to prevent degradation from acidic environments and high temperatures, enabling more efficient energy recovery.
