Shipbuilding steel plates or offshore platform plates are used to make hulls, offshore oil production drilling, platform pipe joints and other structural parts; Our ship steel plates are nine classification societies certified( American ABS, French BV, British LR, German GL, Norwegian DNV, Italian RINA, Japanese NK, Chinese CCS, South Korea KR ). A709 grade 50W low alloy steel sheet, These plates can be Z15 / Z25 / Z35. Our company stocks a large number of shipbuilding plates, A709 grade 50W low alloy steel sheet, offshore platform plate steel in stock.
A709 grade 50W low alloy steel sheet and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of A709 grade 50W low alloy steel sheet and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than A709 grade 50W low alloy steel sheet. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel A709 grade 50W low alloy steel sheet is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
