Manufacturer, Supplier & Exporter of EN 1.4162 Spool
EN 1.4162, also known as X2CrMnNiN21-5-1, is a lean duplex stainless steel grade designed to offer a balanced combination of strength, corrosion resistance, and affordability. This material exhibits a duplex microstructure consisting of approximately equal proportions of austenite and ferrite, which gives it high mechanical performance along with excellent resistance to stress corrosion cracking. Its relatively low nickel content makes it a cost-effective alternative to standard duplex stainless steels while maintaining durability and performance under moderate corrosive conditions..
The chemical composition of EN 1.4162 includes 21–22% chromium, 4–6% manganese, 1.35–1.7% nickel, 0.2–0.25% nitrogen, and 0.10–0.80% copper, with a very low carbon content (≤ 0.04%). This combination ensures good weldability, corrosion resistance, and stability at elevated temperatures. The nitrogen content in particular helps improve strength and resistance to pitting corrosion, making it suitable for industrial applications exposed to mildly corrosive media.
Mechanically, EN 1.4162 displays a yield strength of about 450 MPa and tensile strength above 650 MPa, coupled with an elongation of around 30% and Brinell hardness of ≤ 290. These properties make it suitable for manufacturing pressure-bearing components, structural parts, and spools that require both high strength and toughness. Its ability to retain mechanical performance after welding makes it highly practical for fabrication of spools used in pipelines and chemical plants..
EN 1.4162 spools are primarily used in chemical processing, oil & gas, marine, pulp, and paper industries. The duplex microstructure provides good resistance to chloride stress corrosion cracking and moderate pitting corrosion, making it suitable for pipelines, fittings, and spool assemblies in environments where exposure to seawater or industrial chemicals is common. Its strength-to-weight ratio also allows for more compact spool designs while maintaining durability..
