AISI sae 1020 St52 Hot Rolled Iron/Alloy Steel Plate/Coil/Sheet Q235,Q345 Black Steel Backing Weathering Plate

Carbon steel plate generally refers to carbon structural steel plate. Carbon structural steel plate refers to carbon steel with a carbon content of less than 0.8%. This steel contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, and has better mechanical properties.

Carbon structural steel is generally not heat-treated, and is used directly in the supplied state.

Usually Q195, Q215, Q235 steel has low carbon mass fraction, good welding performance, good plasticity and toughness, and certain strength. It is often rolled into thin plate, steel bar, welded steel pipe, etc. Used in bridges, buildings and other structures and in the manufacture of ordinary rivets, screws, nuts and other parts.

The mass fraction of carbon in Q255 and Q275 steel is slightly higher, the strength is higher, the plasticity and toughness are better, and it can be welded. It is usually rolled into section steel, bar steel and steel plate as structural parts and to manufacture connecting rods, gears and couplings of simple machinery. Sections, pins and other parts.
