What is UNS S31803 / DIN 1.4462?
UNS S31803, also known by its European equivalent DIN 1.4462, is a duplex stainless steel grade that combines the best properties of austenitic and ferritic stainless steels. It consists mainly of chromium (21-23%), nickel (4.5-6.5%), molybdenum (2.5-3.5%), and nitrogen, giving it exceptional strength and resistance to corrosion, particularly in chloride-rich environments.
Key Features of UNS S31803 / DIN 1.4462 Pipes & Tubes
• High Strength: Nearly twice the yield strength of standard austenitic grades like 304 and 316.
• Excellent Corrosion Resistance: Particularly effective against pitting, crevice corrosion, and stress corrosion cracking.
• Good Weldability: Suitable for most welding techniques, maintaining mechanical integrity after welding.
• Cost-Effective: Requires thinner cross-sections due to high strength, reducing material weight and overall cost.
Applications in Spain
With a strong industrial base in regions such as Madrid, Barcelona, Valencia, and Bilbao, Spain relies on high-performance piping systems across sectors like:
• Oil & Gas: Onshore and offshore platforms, piping for seawater systems.
• Chemical Processing: Reactors, heat exchangers, and transfer piping.
