Tool Steel
Tool steel is used for just that, the making of tools mostly. It is well suited for this use because of its distinctive hardness, resistance to abrasion and its ability to hold a cutting edge at high temperatures. At 探花系列 we stock both O-1 and A-2 tool steels. O-1 is an oil-hardening steel and is a very good cold work steel mainly used for items like knives and forks. A-2 is commonly known as an air hardening steel and has good machinability along with a balance of wear resistance and toughness. A-2 is the most commonly used variety of air-hardening steel and is often used for blanking and forming punches, trimming dies and injection mold dies.
