Low temperature impacting test steel plate ASTM A131 Grade FH32
Source:Xin Steel Industry Date:2013/07/24
With alloy elements especially the element Nickel,ABS A131 Grade FH32 shipbuilding steel plate can bear the weather corrosion when using to build ships and vessels.When rolling ABS A131 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.
