Introduction

HFK 650B-S is a C-Cr-B alloyed flux cored wire. This submerged arc hardfacing flux-cored wire is suitable for extremely hard deposits on parts subject to excessively heavy abrasive wear.

Typical applications

Used for surfacing in situations which normal and medium temperature abrasion and corrosion resistance are needed. Application examples include turbine blades, blast furnace bells, and wear plates.
