NV A fishing vessel steel mechanical tests

A131 EH36 steel is high strength marine grade hull structural steel. Its yield strength is no less than 355Mpa, tensile strength is 490-620 Mpa, and elongation is 19% min. NV A fishing vessel steel, EH36 steel strength is close to S355 steel. However, EH36 steel is shipbuilding steel, while S355 steel is carbon structural steel, and can not be certified by classification society. That is to say, S355 steel is not allowed to be used for ship building when there is certificate requirement. A131 EH36 steel is widely used to build ships working in low temperature water.

In order to further promote the ultra-low emission process and the technological innovation of flue gas treatment technology in China's steel industry, the China Institute of Metals and Beijing China-Japan Energy Conservation and Environmental Protection Engineering Technology Co., Ltd. (hereinafter referred to as Beijing China-Japan Alliance) will carry out technical cooperation to promote the activated coke dry process The application of desulfurization and denitrification technology in iron and steel enterprises, the signing ceremony of technical cooperation between the two parties was successfully held recently at the Chinese Institute of Metals.

we also provide the NV A fishing vessel steel welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful NV A fishing vessel steel welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.

NV A fishing vessel steel and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields. The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate. Therefore, the medium and heavy plates manufacturers and users attach great importance to it. The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plates.
