Duplex Alloys

These alloys combine the good properties of both chromium (ferritic) and chromium-nickel (austenitic) stainless steels.

1.4517 (A890)

G-X3CrNiMoCuN 26-6-3-3
This duplex steel has excellent general corrosion resistance. It is also highly resistant to localised corrosion, particularly pitting, crevice corrosion and stress corrosion cracking, and is largely immune to intergranular corrosion. After solution annealing, it is considered to be especially tough when exposed to cold temperatures.
CP models: MKP, MKP-S, MKTP, MKPP, SZMK, MKP-BioIL-BTO, ZMP

1.4460 (329)

X3CrNiMoN27-5-2
This material combines very good mechanical properties with excellent corrosion resistance. It is also particularly suitable for use in acidic or chloride-containing environments and for applications with phosphoric or organic acids.
CP models: MKP, MKP-S, MKTP, MKPP, SZMK, MKP-Bio, IL-BTO, ZMP
