A nickel chrome molybdenum electrode for the welding of alloys similar to Hastalloy B type and for joining and overlaying where severe corrosion is encountered.

Mac Nicro E212

AWS E Ni Cr Mo 2

An electrode designed for welding a range of nickel chrome molybdenum steels and also joining these to ferritic steels.

Mac Nicro E213

AWS E Ni Cr Mo 3

This 625 electrode will weld Inconel 601, 800 and 825.  It will also weld most combinations where alloys are chosen for there ability to withstand severe mechanical stress, corrosion and extreme operating temperatures.

Mac Nicro E213B

AWS E Ni Cr Mo 3

This basic 625 electrode will weld Inconel 601, 800 & 825 and most combinations where alloys are chosen for their ability to withstand  very severe mechanical stress, corrosion and extreme operating temperatures.
