Alloy2205 duplex stainless steel

Alloy2205 duplex stainless steel is a high strength, high corrosion resistance stainless steel material. It is composed of elements such as chromium, nickel, molybdenum and nitrogen, and has excellent corrosion resistance and good welding performance. The biphase structure of this material gives it excellent strength and toughness, and can withstand the use of high temperature, high pressure and strong corrosive environments.

Alloy2205 duplex stainless steel is widely used in Marine engineering, chemical, oil, natural gas, pharmaceutical, food processing and other fields. In the field of Marine engineering, it is used to make offshore platforms, subsea pipelines and Marine equipment that can withstand corrosion and high-pressure environments in seawater.

In the chemical, oil and gas fields, it is used to manufacture reactors, heat exchangers, storage tanks and pipelines, which can withstand strong acids, strong alkalis and high temperature environments. In the pharmaceutical and food processing fields, it is used to manufacture containers, pipes and equipment, etc., to ensure the hygiene and safety of products.
