High carbon steel, often called tool steel, contains carbon from 0.60% to 1.70% and can be quenched and tempered. Hammers, crowbars, etc. are made of steel with a carbon content of 0.75%; cutting tools such as drills, taps, reamers, etc. are made of steel with a carbon content of 0.90% to 1.00%. After proper heat treatment or cold drawing hardening, it has high strength and hardness, high elastic limit and fatigue limit, and its cutting performance is acceptable, but its welding performance and cold plastic deformation ability are poor. Due to the high carbon content, cracks are prone to occur during water quenching, so double-liquid quenching is often used, and oil quenching is often used for small-section parts. This type of steel is generally used after quenching, tempering or normalizing at medium temperature, or in a surface quenching state. Mainly used for manufacturing springs and wear-resistant parts.
1. After heat treatment, high hardness (HRC60-65) and good wear resistance can be obtained.2. The hardness is moderate in the annealed state and has good machinability.3. Raw materials are easily available and production costs are low.| Carbon (max) | Manganese* | Phosphorus (max) | Sulfur (max) | Silicon | Copper (max) | Nickel (max) | Chromium (max) | Molybdenum (max) | Vanadium (max) | Niobium (max) |
