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 A573 Gr 70 structural steel plate, Q355NH weathering steel plates are produced with thickness up to 100mm.
The steel plate for hull structure is also called marine plate or shipbuilding steel. Due to the harsh working environment of the ship, the hull shell is subject to the chemical corrosion of seawater, so the requirements for steel for the hull structure are strict. First of all, good toughness for marine plate A573 Gr 70 structural steel plateis the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.
Try to use A573 Gr 70 structural steel plate high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the A573 Gr 70 structural steel plate temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
We have replenish steel materials stocks, now there are huge stocks of S355JR, A36, A573 Gr 70 structural steel plate A572 Gr 50, 16Mo3, A516 Gr 70, ABS grade A, AH32, AH36, EH36, SPA-H, SG295,SM700C etc steel materials. We can arrange delivery for those stock steel products within short time. Meanwhile, we also provide further processing for the A573 Gr 70 structural steel plate steel materials, such as cutting, drilling, bending, welding, etc. Please do not hesitate to contact us if you have any steel demands.
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.
