Notes for processing of Q235 steel plate

Is the medium and thick board the same as the general board?

Mild steel plates, also known as low carbon steel plates, are structural quality plates that are used for a variety of general construction and industrial applications. Mild steel plates are ductile, easy to machine and have high weldability. Mild steel plates can be fabricated into parts that do not require high strength, such as clamps, mounting plates and spacers.Two of the most common grades of mild steel plates are S275 and ASTM A36. S275 is a popular mild steel grade suitable for various general engineering and structural applications. As a low carbon steel specifications, S275 provides low strength with good machinability and high weldability. Mild steel grade S275 is used widely in the construction, maintenance and manufacturing industries.Mild steel grade ASTM A36 is another popular and widely used carbon structural steels, which is mild and hot rolled. ASTM A36 has good welding properties and is suitable for different kinds of machining processes. With a wide range of applica

Weathering steel forms a protective layer on the surface of the metal substrate through the alloying of Cu, P, Cr, Ni, etc., so that it has high atmospheric corrosion resistance. This type of steel has better weathering properties than weathering steel for welded structures, so it is called high weathering structural steel.Weather resistant steels are high strength, low carbon structural steels including small amounts of alloying elements such as copper, chromium, nickel and phosphorus. As a result of these alloying elements and effects of oxygen and humidity, a protective oxide layer is formed on the surface of the steel. The oxide layer prevents the steel from corroding beneath the surface. The thick oxide layer regenerates itself in case of surface damage. The patinated brown-orange appearance of weather resistant steel is formed when the steel is exposed to various weather conditions like humidity and drought. It takes approximately 18-36 months until the protective layer is formed
