Abstract:
The present disclosure relates to a zinc-based alloy coating for steel strip through a continuous galvanizing process. This zinc-based alloy coating provides the steel with cathodic protection before and after the steel is press hardened processing at a high austenitization temperature up to 950°C. The zinc-based alloy coating also reduces or eliminates the susceptibility to liquid metal embrittlement during or after welding for various types of non-press hardenable advanced ultra high-strength steels. The zinc-based alloy comprises at least one element selected from manganese (Mn) and/or antimony (Sb).
