Product Description

GL grade B (GL-B) shipbuilding steel plate 
1. Typical Applications:
GL grade B (GL-B) shipbuilding steel plates or marine steel plates are used in manufacturing hull, maritime oil extraction drilling platform, platform tube junction and other structural components.
2. Dimension of GL Grade B (GL-B) shipbuilding steel plates :
Thickness: 6mm-200mm
Width: 1500mm-4000mm
Length: 6000mm-180000mm
GL (Germanischer Lloyd) rule has normal strength, high strength and extra high strength steel plate for shipbuilding, onshore/offshore platform and other marine engineering. Bozhong Group specializes in the above ship steel plate and supply GL Grade B steel sheets in superior quality.
 
If need detail information of GL/B steel plate, please check the following:
 

Chemical Composition of GL/B normal strength
Grade	The Element Max (%)
	C	Si	Mn	P	S	Al	N
GL/B	0.21	0.50	2.5×C%	0.035	0.035	0.015

 
Crack Sensitivity:  Pcm = (C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B)%
Carbon Equivalent:  Ceq = (C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15)%
