GB711-2011 Chinese steel standard is used in the manufacture of steel plates with a s420mc galvanealed coil density thickness of not more than 150mm for navigating ships, fishing boats and marine engineering structures in ocean, coastal and inland waterway areas. CCS/NV/GL550 steel is a structural steel for ships and marine engineering, divided into four quality grades A, D, E, F, namely AH550, DH550, EH550, FH550, H is high-strength building materials, and 550 is the lower yield strength.

It has good toughness. By strictly controlling the chemical composition, reducing the content of s420mc galvanealed coil density harmful elements and selecting reasonable heat treatment conditions, NM360 steel plate has good toughness. Therefore, the highly reliable structural parts can be constructed according to the brittle failure of wear-resistant components. Uniform and beautiful quality, s420mc galvanealed coil density using advanced technology and equipment, combined with high and scientific technical management, the material and shape of the product are even and consistent.

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of s420mc galvanealed coil density etc. steel material.
