|
An
18% chrome and 8% nickel austenic grade which gives a higher
corrosion resistance compared with normal chrome alloys. Reduced
carbon increases resistance to inter-granular corrosion after
welding Available in all forms. |

Contains
titanium, which is added in proportion to the carbon content.
This prevent inter-granular corrosion after welding . Can
be used in higher temperatures than most austenitic grades. |
