Q355NH weathering and corrosion resistant steel plate and other weather-resistant steel materials are added with Cu, P, Cr, Ni, Cr and other elements to make it have better atmospheric corrosion resistance, and its corrosion resistance is 2-8 times or even higher than that of ordinary steel plates. High, it can be exposed to the outside world or painted for use during use. Therefore, it is an economical, environmentally friendly and green steel grade.
Q355NH weathering and corrosion resistant steel plate are mainly used for steel structures exposed to the atmosphere for a long time, such as railways, vehicles, bridges, iron towers, photovoltaics, high-speed projects, etc. Used in the manufacture of containers, railway vehicles, oil derricks, port buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
KUAIMA steel company has more than ten years of experience in diversified operations and multi-product transactions, involving round bar, ship plate, seamless pipe, plate, coil, wire, bright bar, pipe fittings and a wide range of carbon steel, alloy steel And more product sizes of stainless steel materials, these products we produce meet national and international quality standards, such as ASTM, ASME, DIN, JIS, ISO, etc. The company has 25 production lines for various products, with an annual output of 500,000 tons, and is committed to Provide high-quality steel products and provide supporting services and solutions for global customers.
