GB/T4171-2008 Q355NHA steel plate is an atmospheric corrosion-resistant steel plate, also called weather-resistant steel plate. It is a low-alloy steel series between ordinary steel and stainless steel. The weathering steel is made of plain carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. Q355NHA steel has the properties of high-quality steel such as toughness, ductility, forming, welding, abrasion, high temperature, and fatigue.
Our company always adheres to the principle of "quality first, customer first", and takes every cooperation seriously, with large inventory. It is our aim that steel products materials, Q355NHA steel specification and quantities can fully meet the requirements of users. Let all our client and cooperative enterprises feel satisfied and considerate!
