VL Grade EH36 steel plate and DNV-GL FH32 steel plate for shipbuilding
Source:Steel Industry Date:2021/04/06
After DNV classification society and GL classification society combined,DNV Grade EH36 and GL Grade EH36 called as VL Grade EH36 steel plate or DNV-GL Grade EH36 steel plate.The supplying specification keeps the same as former DNV class rule and GL Class rule.VL Grade EH36 steel plate shall be done low temperature charp-v NOTCH impacting test at -40 Degree Centigrade,however DNV-GL FH32 steel plate need to be done charp-v impacting test low temperature -60 Degree Centigrade.
100mm thickness heavy steel material DNV-GL FH32 steel plate and 150mm thickness VL Grade EH36 steel plate stock in Shanghai port warehouse ready for shipping by container vessel.EN 10204 3.2 mill certificate would be along with DNV-GL FH32 steel plate when delivery.
