① Nickel is one of the main components, which can improve the strength, toughness and hardenability of steel. When the content is high, it can significantly change some physical properties of steel and alloy and the corrosion resistance of steel
② Chromium is also one of the main components. It has hardenability and wear resistance, corrosion resistance and oxidation resistance
③ As one of the auxiliary alloys, molybdenum can obviously harden and heat strengthen the steel, prevent temper brittleness, remanence and coercivity. Hastelloy is essentially a nickel molybdenum alloy.

① Solution strengthening is an important form of strengthening. It is a phenomenon that the strength and hardness of metal are made by forming solid solution. When the solute content is appropriate, the strength and hardness of the material can be significant, while the plasticity and toughness are not obvious, which is its major feature.
② Aging strengthening includes artificial aging and natural aging. Natural aging strengthening is to strengthen the alloy at room temperature; The artificial aging strengthening is to strengthen the alloy in low temperature heating. Both are based on the premise of solution strengthening, and both are for alloy strength.
③ Annealing: the annealed state is the basic state for discharging. The essence is to transform high-speed steel from austenite to pearlite. The function is the surface hardness and plasticity of high-speed steel, which is conducive to cold deformation processing such as cutting; Make the composition and properties of steel even, for further heat treatment; Stress to prevent deformation or cracking.
