Product Introduction

2205 (S32205,1.4462) duplex stainless steel pipe is a high-performance pipe widely used in the industrial field. This type of steel pipe combines the advantages of austenitic and ferritic stainless steels. With its excellent mechanical properties and corrosion resistance, it has become an ideal choice for harsh environments such as chemical industry, marine engineering, oil and gas transportation. HT PIPE is a 2205 Pipe supplier with 15+ export experience. Contact us for more information and quotes for free!

Temperature limit of duplex stainless steel uns s31803

The long-term use temperature should not exceed 300℃ to avoid the reduction of toughness due to the precipitation of brittle phase or σ phase at 475℃.

Medium matching of duplex steel 1.4462

In strong reducing acid (such as concentrated sulfuric acid) or high-concentration alkaline environment, corrosion resistance needs to be verified by experiment.

Work hardening of f51 material

Cold working may lead to an increase in hardness, and annealing is required to restore plasticity to avoid cracks in subsequent installation.

Surface treatment of s31803 steel pipe

Pickling and passivation treatment can enhance the integrity of the passivation film and improve the ability to resist pitting corrosion.
