Product Introduction

SUS329 is a dual-phase stainless steel, known for its high strength and corrosion resistance. This type of stainless steel is formed by a balance of austenite and ferrite microstructures, offering excellent mechanical properties and high resistance to stress corrosion cracking. Additionally, it boasts good wear resistance, corrosion resistance, and high-temperature performance. Consequently, SUS329 finds applications in industries such as chemicals, marine engineering, shipbuilding, textiles, and pulp and paper manufacturing.

For the chemical industry, SUS329 stainless steel stands out for its corrosion resistance, maintaining excellent stability and durability even in harsh acidic or alkaline environments. In pulp and papermaking industries, among others, the corrosion and wear resistance of SUS329 stainless steel effectively extends the lifespan of equipment. In marine engineering and shipbuilding, it is highly favored for its good resistance to seawater corrosion and high strength.

The primary alloy elements of SUS329 stainless steel are Cr, Ni, Mo, and N, with a higher Cr content to enhance its corrosion resistance. Additionally, the Mo content boosts the material's rust-proofing ability, and the addition of N improves the strength and corrosion resistance of the stainless steel. However, it's important to note that due to its higher hardness, processing requires better tool quality and increased difficulty.
