Air Hardened Alloys

The CS ranges of welding consumables are based on carbon, manganese, chromium and molybdenum alloys with a lime-fluorspar flux fill, and are easy to in either an open-arc or a self-shielded format. As no shielding gas is required the CS wires are as suitable for remote, on-site work as they are for workshop procedures.

 

BS11B is an open arc, self-shielded, wire developed with Railtrack in the UK specifically for repair welding on normal and 'A' grade rail steels.

 

CS70
...suitable for single- and multi-pass welding of mild steel in flat, horizontal or vertical positions. CS70 is also ideal for non-critical welding of general and structural steel work, and for building-up a surface prior to applying hardfacing.
