What it is used for
Furnace parts, flue gas and dry heat, where X18CrN28 has to hold its scale.
Limits
Dry heat. Not a first choice in wet chlorides — that is 316L or duplex.
Delivery
We source X18CrN28 from European mill partners as seamless tube, welded tube, cut to your dimensions and ship the certificate with the material. Typical condition: solution annealed. From a single cut length to full bundles — with no minimum charge.
Certificates and documentation
X18CrN28 can be supplied with a material certificate to EN 10204, depending on producer, dimension and the requirements specified for the delivery. On stainless, the analysis and the delivery condition are what the certificate shows. If a specific test or an ageing/hardening condition is to be documented, it must be specified before we order. EN 10204 3.1 can be supplied on a wide range of our materials.
