What are the Differences Between Hot Work Tool Steel and Cold Work Tool Steel?

Both hot and cold work tool steels have different characteristics, making them suitable for different purposes. Being the best Steel Dealers in Punjab, we deal in steel which our customers use for various objectives. These two types of steel have distinguished features, due to which they command high demand.

We have a list of features and qualities that makes these two steels the best in their purposes, given below:

Hot Work Tool Steel

This type of steel is used to make iron and non-ferrous metals, along with metal tools that maintain their strength even after being exposed to hotter temperatures. 

People use Hot Work Tool Steel India for its high strength, hardness, and thermal stability. Tools like hammers, forging dies, hot extrusion dies, and die-cast dies are made of this steel.

Types of Hot Work Tool Steels

There are three types of hot work tool steel, classified on the basis of their chemical composition given below: 

  1. Chromium Hot Work Tool Steel: Their steel gradings are from H10 to 19. Their carbon composite is about 0.34 to 0.40. Their normal working temperature is below 540 degrees centigrade. Their average working harness is 400 to 600 HV.
  2. Tungsten Hot Work Tool Steel: Their steel grade is from H21 to H26. Their normal working hardness is 450 HV to 600 HV.
  3. Molybdenum Hot Work Tool Steel: Their steel grade numbers are H41, H42, and H43. This type of steel is low in carbon. 

Cold Work Tool Steel

This steel is used to shape or deform metal in cold temperatures. It has high wear resistance, toughness, and cold bite resistance and can soften when heated. People use this type of steel for short-term functions. The presence of tungsten, manganese, chromium, and molybdenum makes this type of steel useful for its purpose. People use this steel for gauges, blanking and forming dies, fixtures, etc.

Operating Temperatures of both the steels

Cold work tool steel can work in temperatures below 100 degrees centigrade. On the other hand, hot work tool steel generally works at temperatures ranging from 350 to 700 degrees Celsius.

Elements in Both Steels

Cold work tool steel has a higher amount of carbon to achieve higher hardenability and wear resistance. Sometimes water-hardening and oil-hardening steels are added to this steel to enhance the hardenability and wear resistance.

Hot work tool steel has more elements to achieve hardness, thermal conductivity, and wear resistance. These elements also help this steel to achieve more oxidation and the ability to withstand higher temperatures.

Many people use these types of steel for various purposes. Some tools made out of these steels have proven quite helpful to us. Their properties and abilities have proven their significance in various industries. But hot steel has the ability to withstand the most brutal temperatures, which makes it more useful. 

We have the best quality steel to offer. Whatever you demand from these steels, you will get the desired result. We sell the best quality steel to the people of Punjab. We have the best experience and knowledge in terms of steel.
