We use BISPLATE500 instead of NM400, this could improve the resistance of the bucket.
The main products that we produce are excavator bucket and cleaning bucket,the main cutting plate are made of BISPLATE 500, instead of NM400, full thickness hardening, good damage resistance, its service lift increase by at least 30%, approved by our customers. See the following for the mechanical properties of the steel plate:
