The difference between alloy steel and alloy tool steel

1. The difference in meaning:
Alloy steel is called alloy steel by adding other alloying elements besides iron and carbon. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements to ordinary carbon steel.
Alloy tool steel is a type of steel that adds alloy elements such as chromium, molybdenum, tungsten, and vanadium to carbon tool steel.
2. The difference in use:
Alloy steel is used in excavator buckets, ball mill liners, etc., to manufacture various elastic components such as constant coil springs, leaf springs, etc.; molds that plastically deform metals at room temperature, such as blanking dies, cold heading dies, and shear dies etc.; molds for thermal deformation processing of metals, such as hot forging dies, die-casting dies, etc.
Alloy tool steel is widely used as cutting tools, cold and hot deformation molds and measuring tools, and can also be used to make pistons, valves, valve seats and fuel valve nozzles of diesel fuel pumps.
3. The difference in characteristics:
The characteristics of alloy steel are sufficient strength and creep resistance, good plasticity and toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetism, and strong oxidation resistance.
The characteristics of alloy tool steel are high hardenability, hardenability, toughness and sufficient wear resistance.
