Duplex Steel S31803 Plate Sheet:

Duplex Steel S31803 Plate Sheet is made of a type of austenitic-ferritic stainless steel that exhibits excellent physical and mechanical properties along with superior corrosion resistance. ASTM A240 UNS S31803 Plate is composed of a mixture of chromium, nickel, molybdenum, and nitrogen, which gives the material increased strength and resistance to highly concentrated solutions of chloride ions. Duplex SA 240 S31803 Plate is commonly used in the chemical, pulp and paper, and oil and gas industries.

 

Duplex Steel S31803 Plate Sheet also has a good corrosion cracking resistance capacity. 10mm Duplex S31803 Plate also has good notch ductility at ambient temperatures and sub-zero temperatures. Duplex SA 240 S31803 Plate can be used as a replacement to ordinary austenitic stainless steel type coils. ASTM A240 UNS S31803 Strips could be used in fairly strong applications with less corrosion risks. ASTM A240 GR S31803 Shim Sheet is applied in pressure vessels and offshore rigs. Duplex SA 240 S31803 Brushed Finish Plate is also used in chemical processing, transport and storage structures.

 

S31803 stainless steel plate Chemical Composition:

The typical chemical composition of Duplex S31803 stainless steel plate sheet includes 22% chromium, 5-6% nickel, 3% molybdenum, 0.18-0.2% nitrogen, and 0.08-0.2% carbon. The presence of these elements gives the steel a great combination of strength, formability, and corrosion resistance.

Physical Properties:

The duplex S31803 stainless steel plate sheet exhibits excellent physical properties that make it ideal for various industrial applications. The material has a density between 7.8 to 8.0 g/cm³ and a melting point of approximately 1350°C. It has a maximum operating temperature of 250°C and a minimum yield strength of 450 MPa.

 

This type of stainless steel is commonly used in the chemical, oil, and gas industries due to its high corrosion resistance, strength, and durability. It is used in the production of heat exchangers, pressure vessels, and chemical processing equipment. Duplex S31803 stainless steel is also used in the construction of offshore platforms and subsea pipelines.
