Product Description

hot rolled seamless stainless steel pipes Super duplex steel S31803 Polished Seamless tube

Material properties:

S31803 duplex stainless steel pipe is a medium alloy duplex stainless steel with good resistance to chloride stress. It is widely used in industry due to its excellent corrosion resistance and high strength. It has good resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking, especially suitable for chloride containing environments. S31803 has high strength, good toughness and ductility, and is suitable for fields such as chemical engineering, oil and gas, and marine engineering. It also complies with international and national standards such as ASME, ASTM, and EN. 1. Corrosion resistance: S31803 duplex stainless steel exhibits good performance in many corrosive environments, especially with high resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking, especially in chloride containing environments; 2. Mechanical properties: Due to its unique dual phase structure of ferrite and austenite, S31803 has higher strength than conventional austenitic stainless steel (tensile strength generally exceeds 500 MPa), while maintaining good toughness and ductility; 3. Weldability: Although welding processes require special attention to prevent tissue degradation in the heat affected zone, good welding results can be achieved through appropriate welding techniques and post-treatment methods

Metallographic structure:

S31803 stainless steel (austenitic ferritic structure).

Application field:

1. In the field of petrochemicals, S31803 stainless steel has a wide range of applications. Due to its excellent corrosion resistance and good strength, it can be used to manufacture petrochemical equipment, pressure vessels, pipelines, etc. Among these devices, S31803 stainless steel can effectively resist the corrosion of various chemicals, ensuring the service life and safety of the equipment; 2. Oil and gas: In the oil and gas industry, duplex stainless steel S31803 plays a crucial role in helping to resist harsh conditions. This is because its strength, resistance to pitting and crevice corrosion are superior to standard austenitic stainless steel, and the pitting equivalent value (PREN) of duplex stainless steel is usually higher than 40; 3. Construction industry: Dual phase stainless steel continues to play an important role in bridge construction. Bridges are used in corrosive and saline environments, while requiring high bearing strength; 4. Chemical equipment: S31803 duplex stainless steel has excellent corrosion resistance and wear resistance, and can be used to make chemical storage tanks, heat exchangers, tower tanks, pipelines and other equipment; 5. In the field of ocean engineering, high requirements are placed on the corrosion resistance and strength of materials. S31803 stainless steel, as a duplex stainless steel, has been widely used in the field of ocean engineering. It can be used to manufacture facilities such as ocean platforms, ships, and subsea pipelines. Among these facilities, S31803 stainless steel can effectively resist the corrosion of seawater, ensuring the service life and safety of the facilities.
