HIGH CARBON STEEL PLATES

The High Carbon Steel Plates is having carbon ranging from 0.40% to 1.00% with the manganese ranging from 0.30% to 0.90%. The pearlite is having a fine structure that is making the steel harder. Unfortunately, this is making the steel brittle and less ductile than mild steel. High carbon and medium steel are used widely in many applications. The increasing carbon as the main alloy for steel hardness and high strength is the economical approach for well-improved performances. Some of the effects of the elevated carbon level are including reduced weldability, impact toughness, and ductility.

High carbon steel is one of the most important construction metals in the world. High carbon steel will be any type of steel that contains over 0.40% carbon but less than 2.11% carbon in its composition. The average level of carbon found in this metal usually falls right around the 1.5% mark. High Carbon Steel Plates has a reputation for being especially hard, but the extra carbon also makes it more brittle than other types of steel.
