NHF-HMn

Specification

Description

• NHF-HMn is an electrode containing 14% manganese for austenitic, non-magnetic weld metal suitable for joining and rebuilding components of the same type subject to abrasion service with impact

Application

• Steel rail ends
• Dredge buckets
• Heavy crushing equipment
• Jaw crusher
• Swing hammer
• Tooth crusher rolls
• Ore crusher crown wheels

Remarks

Avoid continuous welding

Recommend to water cool during welding

It is necessary to underlay with austenitic stainless steel in such case when the base metal is not 13% manganese steel

When the base metal of 13% manganese steel is hardened, remove it before welding

Dry the electrodes at 150 - 200ºC for 30 - 60 minutes before use
