Title:

Ni BASE HIGH Cr ALLOY FILLER MATERIAL AND WELDING ROD FOR SHIELDED METAL ARC WELDING

Document Type and Number:

WIPO Patent Application WO/2005/070612

Kind Code:

A1

Abstract:

An Ni base high Cr alloy filler material or a welding rod for shielded metal arc welding, which has a chemical composition, in wt %, that C: 0.04 % or less, Si: 0.01 to 0.5 %, Mn: 7 % or less, Cr: 28 to 31.5 %, Nb; 0.5 % or less, Ta: 0.005 to 3.0 %, Fe: 7 to 11 %, Al: 0.01 to 0.4 %, Ti: 0.01 to 0.45 %, V: 0.5 wt or less, and, as inevitable impurities, P: 0.02 % or less, S: 0.015 % or less, O: 0.01 % or less, N: 0.002 to 0. 1 %, and the balance: Ni. The above Ni base high Cr alloy filler material inhibits the generation of a scale and thus can enhance the resistance to weld crack satisfactorily and the above welding rod exhibits satisfactorily enhanced resistance to weld crack.
