Thanks to their state-of-the-art processing facilities and a talented workforce, Chetan Steel guarantees consistent performance, dependable supply, and timely delivery to various sectors, including engineering, automotive, tooling, and heavy fabrication industries throughout India.
High Carbon Steel C55 generally contains about 0.52–0.60% carbon, along with controlled amounts of manganese, silicon, sulfur, and phosphorus. This elevated carbon content gives it remarkable hardness, strength, and wear resistance, especially when compared to medium-carbon steels. C55 sheets and plates showcase impressive tensile strength, excellent edge retention, and improved fatigue resistance after undergoing heat treatment. They respond effectively to quenching and tempering, allowing for adjustments in hardness and toughness. However, due to the high carbon content, welding can be tricky and requires careful preheating and controlled techniques.
