NSSC 220M

High performance of rust resistance is available in this grade, which has been developed by combined addition of Ti and Nb to 22%Cr-1.6% Mo ferritic base material.

1. Rust resistance superior to that of SUS 316.
2. Lower thermal expansion coefficient suitable for such applications as roofs and exterior walls in which thermal expansion and contraction are problematic.
3. Slightly higher hardness than SUS 304 due to high chromium content.
4. Applications: Exteriors of buildings, such as roofing, siding, or others.
