BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of NV E40 hull structural steel plates steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main NV E40 hull structural steel plates production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.
Q355NH steel plates and sheets with atmospheric corrosion resistance are mainly used for vehicles, bridges, containers, buildings, towers, and other structures. Weather-resistant steel can be used to make bolted, riveted and welded structural parts. We can also slit and sheet Q355NH (Equivalent A588 steel) to any weight and size for immediate delivery. Our NV E40 hull structural steel plates, Q355NH weathering steel plates are produced with thickness up to 100mm.
The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the NV E40 hull structural steel plates and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.
Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. NV E40 hull structural steel plates Heat treatment process refers to the ability to change the microstructure and properties of NV E40 hull structural steel plates after heat treatment, including hardenability, hardenability, temper brittleness, etc.
The yield strength of NV E40 hull structural steel plates, Q235 steel plate decreases with the increase of thickness. Q235 steel plate thickness≤16mm, yield strength is 235MPA; 16mm < Q235 steel plate thickness≤40mm, yield strength is 225MPA; 40mm < Q235 steel plate thickness≤60mm, yield strength is 215MPA; 60mm < Q235 steel plate thickness≤100mm, yield strength is 205MPA; 100mm < Q235 steel plate thickness≤150mm, yield strength is 195MPA; 150mm < Q235 steel plate thickness≤200mm, yield strength is 185MPA.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the NV E40 hull structural steel plates principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
