AWS ER-RCoCr-B

Commonly called satellite 12

 

NHF-ST-12R bare rod is developed for high hardness, abrasion resistance and good corrosion resistance. These properties make NHF-ST-12R the choice for wood cutting saws & bars, and for industrial cutting applications for carpet, plastics, papers and chemical industries. It is non-forgeable and can be machined with difficulty using carbide tools. NHF-ST-12R bonds well to all weldable-grade steels, including stainless.

 

NHF-ST-12R is used in the following applications:

Valve plugs and seats

Chain saw guide bars

Turbine engine seals

Scissor blades

Saw teeth and blades

Rotary cutters

Twist rolls

Wood cutting tools

Pump sleeves

Extrusion dies

 

NHF-ST-12R is a solid wire product used for TIG and brazing applications. MIG wire for this item is not available.
