Description and Applications |
HJ450 is a low
hydrogen type electrode, which is subjected to
metal-to-metal abrasion.
Suitable for building up and repairing machinery which
is used in civil engineering. For the welding of worn
out parts which require high abrasion resistance and can
be used without machinery. |
