LR EH36 shipbuilding steel plate
Introduction to EH36 steel plate: EH36 is a steel plate with a thickness of no more than 150mm for manufacturing ocean going, coastal and inland navigation ships, fishing boats and offshore engineering structures. The steel plate with Z direction requirem
JIS G3125 SPA-H steel plate chemical composition
CR can also form a dense oxide film on the surface of JIS G3125 SPA-H steel plate, improve the passivation ability of the steel and slow down the growth rate of rust layer. However, due to the selective oxidation of Cu, the Added Cu alone will be enriched
A588 grade A weathering steel plate
A588 grade A weathering steel plate refers to adding a small amount of Cu, Cr, Ni and other alloy elements to ordinary low alloy steel to form a dense amorphous oxide layer with strong adhesion to the base metal between the rust layer on the steel surface
