Alloy Tool Steel Applications and Properties

DONGGUAN, China - Sept. 18, 2024 - PRLog -- Alloy tool steel is the type of steel which was added certain alloy elements at the base of the carbon tool steel to get higher properties. Compare with the carbon tool steel, it has higher hardness, toughness, wear resistance, hardenability, and hot hardness. And it has more steel grades. The properties of them are various, which means it can satisfy easily all kinds of requirements for different tools. So, it can be used to make all kinds of cutting tools, measuring tools and molds with big size, complex shape and high requirements for properties.

The carbon content for alloy tool steel is much higher. Most of them are also belong to high carbon steel. The elements were added are W, Mo, Cr, V, Mn, Si and etc. If the total amount for alloy element is less than 5%, then it is a low alloy tool steel. If it is in the range of 5%-10%, then it is a medium alloy tool steel. But, if it is bigger than 10%, it belongs to high alloy tool steel.

At present, most of them are low alloy tool steel. According to the applications, they can be divided into cutting tool steel, measuring tool steel and mold steel(cold work mold steel, hot work mold steel). And the common heat treatment way for alloy tool steel is quenching and tempering in the low temperature. But the hot work mold steel has great toughness, so it usually takes the way of quenching and high-temperature tempering.

Alloy Tool Steel Properties and Be Used for
GB 9SiCr / DIN 90SiCr5
GB 9SiCr steel is also equivalent to DIN 90SiCr5 and BS BH21 steel. Its hardenability is better than chromium steel. The steel round bar with a 45mm – 50mm diameter can be hardened in the oil. It has good wear resistance and tempering stability. But its machinability is not good. The deformation during the heat treatment is small, but the decarburization tendency is higher.

Alloy Tool Steel for Sale
Different alloy tool steel grade has own identity, that means they play a different role in the industry and life. If you need to buy alloy tool steel, please make sure what steel grade is your need in the perfect way, according to the requirements of hardness, toughness, strength, specification and more. Those things will impact the alloy steel price, that is the important thing you need to know.
