Introduction of high carbon steel
After proper heat treatment or cold-draw hardening, high-carbon steel has high strength and hardness, high elastic limit and fatigue limit, cutting performance is acceptable, but welding performance and cold plastic deformation ability are poor. Due to the high carbon content, cracks are easy to occur during water quenching, so two-liquid quenching is often used, and small-section parts are mostly oil quenched. This type of steel is generally tempered or normalized after quenching or used under surface quenching. Mainly used in the manufacture of springs and wear parts. Carbon tool steel is a high-carbon steel that basically does not add alloying elements. It is also a low-cost tool steel with good cold and hot workability and a wide range of use. Its carbon content is between 0.65 and 1.35%, and it is a steel specifically used for making tools. The density of high carbon steel is 7.81g / cm³. Can be used in the production of fishing gear.
