Normal strength shipbuilding structural steel is divided into four grades: A, B, C, and D. The yield strength (not less than 235N/mm^2) of EN 10155 S235J0W, S235J2W weather resistant steel these four grades is the same as the tensile strength (400~520N/mm^2). However, the impact properties of steel plates at different temperatures are different.

Cold rolled coil products EN 10155 S235J0W, S235J2W weather resistant steel have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products EN 10155 S235J0W, S235J2W weather resistant steel is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils EN 10155 S235J0W, S235J2W weather resistant steel with different surface roughness can be produced (glossy surface or matte surface, etc.).

The influence of thermal physical properties and mechanical properties of composite wear-resistant steel plate on laser bending is complex, which mainly involves the thermal expansion coefficient, specific heat capacity coefficient, thermal diffusion coefficient, yield limit, elastic modulus and hardening index. Under the same process conditions, the greater the specific heat and thermal conductivity of the composite EN 10155 S235J0W, S235J2W weather resistant steel, wear-resistant steel plate, the less obvious the temperature gradient in the forming process, and the smaller the bending angle produced.

Our focus on quality has helped us create an efficiently organised production system, which can supply large-scale piping orders as well as tailor-made orders for smaller clients. We have also created a sales and support network which stretches from Asia to Europe, UAE, South Africa and South America.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
