II. DESCRIPTION:

NHF ST-12R bare rod develop high hardness and abrasion resistance and good corrosion resistance. These properties make NHF ST-12R the choice for wood cutting saws and bars and for industrial cutting applications for carpet, plastics, papers, and chemical industries. It is non- forgeable and can be machines with difficulty using carbide tools. NHF ST-12R bonds well to all weldable-grade steels, including stainless. NHF-ST-12R is a solid wire product used for TIG and brazing applications. MIG wire for this item is not available.
