GL Grade B ship plate mainly used to build vessels which are sailing in common ocean waters at about zero centigree.Xinsteel foucs on rolling wide heavy shipbuilding plate of GL Grade B,up to today,we can roll the maximum thickness for shipbuilding plate GL Grade B shall be 450mm,and the maximum width shall be till 4200mm.This owned world-class property.For the thickness above 40mm,our engineers suggest customers accept doing Normalized heat treatment for GL Grade B steel plates.
The best important test for shipbuilding steel plate GL Grade B is Z-test,Z-test is for thickness nondestructive test for steel plate which including three different grades,such as Z15,Z25,Z35.For Grade E plates, now we can roll ABS Grade B,LR Grade B,BV Grade B,DNV Grade B,NK Grade B,CCS Grade B,KR Grade B, GL Grade B and RINA Grade B.Now we give you the mechnical properity and chemical composition for marine steel plate GL Grade B for your reference.
