Buy Hot Work Steel without any Minimum Order Value or Quantity

Hot work steel has an excellent combination of mechanical and metallurgical properties. It is used for applications with a surface temperature above 392 °F (200 °C) and has to withstand extended thermal loads, changing temperatures and thermal abrasion.

During hot working metal, it is deformed above the recrystallization temperature but below the melting point. Working with this kind of heat, controlling the temperature of the workpiece is crucial to get the best results.

THE ESSENTIAL PROPERTIES OF HOT WORK STEEL

Hot work steel has to be able to withstand cycles of high heat and cooling down as well as keeping its mechanical properties.  
1. High temperatur strength: Hot work tool steel has the ability to maintain its structural integrity, mechanical properties and dimensional stability when exposed to high temperatures.

2. Termal fatigue: Thermal fatigue occurs when parts are subjected to recurring high temperatures and cooling. Hot work steel has a resistance to thermal fatigue and can endure the constant change in temperatures.

3. Thermal conductivity: Thermal conductivity is a very important property of hot work steel. Heat has to be distributed evenly as not to crack or warp the material and improve tool life as well as process stability.

4. Toughness: is important for hot work steel as it not only has to withstand high heat but also impact at the same time. Toughness is important to keep the ductility needed when great forces are used on the workpieces.
5. Hardness: Hot working metals have a good hardness to give it the needed wear resistance, durability and edge retention and has to be carefully balanced with toughness to ensure an overall reliability.

6. Fatigue resistance: is needed when parts or workpieces are exposed to repeated or cyclic stresses.Hot work steels have to resist high temperatures as well as mechanical stresses.

7. Shock resistance: The combination of toughness, formability, a refined grain structure, balanced hardness and suitable heat treatment adds to the high impact strength of hot work tool steel grades and makes them indispensable for reliable and long-lasting performance in demanding industrial environments.

8. Wear resistance: Applications like hot forging, hot extrusion or die casting expose the material to tough working conditions. High wear resistance ensures a long service life by maintaining shape, dimension and integrity.

WHAT ARE HOT WORKING PROCESSES?

Hot Forging

Forging with dies is carried out by hitting the material with a hammer or by applying high pressure from a forging press.

In addition to withstanding the temperatures of the forging, the die must have good mechanical properties such as toughness in order to withstand the pressures or blows.

hot-drawing-hot-work-steel

Drawing


During this process heated material is drawn through a die to increase its length.


Dies and tools used to draw hot material have to be heat resistant, and wear resistant to keep the exact shape for the continuous production of precise parts.

Hot spinning


Hot spinning, the metal which needs to be formed rotates while it is heated by an external heat source and then formed by pressure.


The tools used to form the metal are usually made from hot work steel so as not to be affected by the heat the material reaches.

hot-spinning-hot-work-steel
hot-rolling-hot-work-steel

Hot Rolling


During hot rolling, heated steel is rolled between rollers to the desired shape and thickness.


Due to the contact heat and the required pressure, the rolls must not deform, break or crack.

WHAT ARE THE ADVANTAGES AND DISADVANTAGES OF HOT WORK STEEL?

Like any process, hot working has some advantages but also disadvantages. Find some of them below.

Advantages

Disadvantages

High temperature strength:

Suitability of the material for high heat applications with the retention of strength and hardness

Surface oxidation and scaling:

Due to the high temperatures the surface can oxidate and form scale. This does lead to an additional work step to eliminate the scaling.

Enhanced toughness and ductility:

Due to a finer grain structure hot work steel has a better toughness and ductility, preventing cracking and breaking while absorbing high impacts.

Dimensional accuracy:

To achieve precise dimensional tolerances can be challenging as hot worked material might experience thermal expansion.

Grain refinement:

Hot working leads to a more uniform and finer grain structure. This improves the mechanical properties of the material.

Energy consumption:

To maintain the hot working temperature a significant energy input is needed.

Reduction of internal stresses and defects

Hot worked metal has fewer internal stresses and defects.

Potential of grain growth:

Uncontrolled temperatures during the hot working process can lead to grain growth and the reduction of mechanical properties.

Longer tool life

With its resistance to high temperatures and wear, tools made from hot worked steel have a longer tool life.

Material loss due to scaling:

If the material scales during hot working it may require additional machining resulting in possible material loss.

SUMMARY


• Temperature above the recrystallization

• Enhanced mechanical properties
• Refined grain structure
• Reduced internal stresses and defects
• Less flow stresses
• No strain hardening
• Longer tool life
