Product Introduction

GNEE is an experienced stainless steel pipe supplier that can provide you with A789 S32205 Duplex Steel Seamless Pipe in all grades and size ranges.
A789 S32205 Duplex Stainless Steel Pipe is called "duplex" because it has a two-phase microstructure consisting of ferrite and austenite stainless steel grains. The chemical composition of A789 S32205 Round Pipe includes elements such as chromium, nickel, and molybdenum. It consists of 22% chromium, 5-6% nickel, and 3% molybdenum. The high amount of molybdenum, chromium, and nickel provides excellent efficiency to the product.
A789 S32205 Mechanical Pipe With its duplex microstructure, these pipes have higher strength and durability compared to traditional austenitic stainless steel. This makes them suitable for applications that require strong mechanical properties.
