■ Overview
With alloy elements especially the element Nickel,KR Grade FH32,KR FH32,KR FH32 steel plate can bear the weather corrosion when using to build ships and vessels.When rolling KR Grade FH32 steel plate,the steel should be chosed as full killed and hot rolling.Normalized heat treatment have to be done when the steel billets finished.Low temperature impacting test should be made under minus 60 centigree.
