Lincoln LNT 9Cr
Designed for welding equivalent type 91~ 9% Cr Steels modified with small aditions of Niobium, Vanadium and Nitrogen to offer improved long term creep properties. This alloy is specialy intended for high integrity structural service at elevated temperature such as: Headers, main steam piping and turbine casings, gasification plants etc.

This alloy is specialy intended for high integrity structural service at elevated temperature such as: Headers, main steam piping and turbine casings, gasification plants etc.
Filler metal specifically intended for high integrity structural service at elevated temperature so the minor alloy additions responsible for its creep strenghth are kept above the minimum considered necessary to ensure satifactory performance.
