Hot Rolled Q345B Low Alloy Carbon Steel Plate

A carbon steel plate has usually been considered as the steel that does not contain much alloy steel elements, also named as mild steel. Generally, elements are C, Mn, P, S, Si, besides these, there are no minimum limits for elements of Al, Cr, Ni, Mo, V, etc. Carbon steel plates are available in different grades depending on the carbon content and strength. As the content of Carbon increase, the steel plate hardness increases. Low carbon steel plate: For carbon content 0.06% to 0.25%, also we call it mild steel plate. Medium carbon steel plate: C content from 0.25% to 0.55%. High carbon steel plate: 0.55% to 1.0%, also called hard steel plate. Low carbon steel is the most common form, and it's very malleable and ductile. Medium carbon steel balances ductility as well as strength for excellent wear resistance. High carbon steel is exceptionally strong, while ultra-high carbon steel can be tempered to even greater hardness but no malleability. Mi…
