Overview of S31803 Duplex Stainless Steel
S31803 duplex stainless steel is a nitrogen-enhanced alloy composed of 21% chromium, 2.5% molybdenum, and 4.5% nickel. This combination ensures superior strength and corrosion resistance. A significant feature of S31803 duplex steel is its yield strength, which is double that of traditional austenitic stainless steels. This characteristic allows for lighter designs in product manufacturing and offers a cost advantage over 316/317L stainless steels. Optimally used within the temperature range of -50°F to +600°F, the alloy is also viable beyond this range, though limitations may apply, especially in welded structures. S31803 duplex steel's unique properties make it the most popular grade of duplex steel, widely used across various applications.
Physical and Mechanical Properties of S31803 Duplex Stainless Steel
Density: The density of S31803 duplex steel is 8.0 g/cm³.
Tensile Strength: The tensile strength (σB) is at least 620 MPa, indicating the maximum stress it can withstand before failing.
Yield Strength: The yield strength (σ0.2) is at least 450 MPa, marking the stress at which permanent deformation begins.
Elongation Rate: The elongation rate (δ) of at least 25% demonstrates the steel’s ability to stretch under tension, highlighting its ductility.
This comprehensive set of properties demonstrates why S31803 duplex steel is highly favored for its robustness and versatility in challenging environments.
We provide the very best quality pipe and fittings, prompt delivery and reliable services at competitive prices.
