Leave a message
If you are sourcing stainless steel for structural, architectural or industrial use, EN 1.4404 stainless steel hollow sections are the ideal choice for your needs, offering exceptional corrosion resistance, excellent formability and long service life.
What Is EN 1.4404 Stainless Hollow Section?
EN 1.4404, also known as X2CrNiMo17-12-2, is the European standard equivalent of AISI 316L stainless steel, designed for use in highly corrosive environments. Hollow sections made from this alloy come in various shapes:
Rectangular hollow sections (RHS)
Square hollow sections (SHS)
Circular hollow sections (CHS or tubing)
They are typically manufactured according to EN 10210 (hot-formed) or EN 10219 (cold-formed) standards.
