The edge of the axe cutter can be quenched with water, gas double medium, first water-cooled, then slid out, paused in the gas for a few seconds, then water for a few seconds, then slid out again, and then paused for a few seconds in the gas. This is so reciprocating until it cools to the indoor temperature and normal temperature.
Axe cutter edge
quenching typical case
The purpose of quenching the edge of the axe cutter is to transform the supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then mix it with heat treatment at different temperatures to greatly increase the steel. Strength, hardness standards, wear resistance, fatigue strength and flexibility, etc., to consider the different requirements of various mechanical parts and tools. It is also possible to use quenching to consider the physical and chemical properties of special steels such as ferromagnetism and corrosion resistance.
Typical case after axe cutter edge quenching
A heat treatment process for quenching, metal and tempered glass. The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hyper-eutectoid steel), keep it for a certain period of time, make it all or part of austenite, and then after cooling more than critical The rapid cooling rate of the velocity is rapidly cooled to the heat treatment process of martensite (or bainite) transformation under Ms (or isothermal near Ms). Generally, aluminum alloy profiles, alloy copper,
The solution treatment of a raw material such as a titanium alloy or a tempered glass or a heat treatment process with a rapid cooling process is called quenching.
