How does Heat Treating Contribute to the Heavy Construction Machinery Industry?

In an industry where time, money, and safety are integral in providing reliable machinery to do specific building tasks, all you want is for its components to work as designed. Aside from investing in the equipment, mechanical failure can be costly for manufacturers, contractors, and developers. They cost projects delayed and sky-high amounts of claims.

These heavy types of machinery play a huge role in completing construction projects at the targeted time. For metal manufacturers, meeting critical specifications for machinery components is a must. That is why materials should undergo durability tests with tensile test sample preparation equipment. Otherwise, the operability and mechanical integrity will be questionable.

And because these components are mainly composed of heavy metal components, applying the necessary heat treatment is crucial.

Heavy Types of Machinery Used in Construction and their Components

When we are talking about heavy equipment, we mean those that do specific tasks like lifting heavy loads of construction materials, excavating, digging, or lifting soils from properties or trenches. 

What Are the Heavy Machinery Used in Construction?

These are just a few of the many construction types of machinery that help make building easier.

• Dozer
• Excavator
• Lifter
• Scraper
• Motor grader
• Pavers and roller
• Trencher
• Loader
• Skid Steer

And looking at these examples, you can guess the reliance on durable and specifically-heat-treated metal components. Otherwise, the machine’s integrity will be compromised. See, engineers designed these pieces of machinery to do specific tasks, and using unreliable machine components will result in machine failure.

Heavy Machinery Components that Undergo Heat-treating

Metal components of different types of machinery require different heat-treatment procedures. Every part goes through various stress or strain while the machine is working.

These heavy machinery components range from bucket and spade teeth, hydraulic cylinders, pistons, gaskets, sprockets, steel blades, couplings, pulleys, hooks, bearings, crankshafts, or valves. 

Heat-treating enables these parts to meet specific mechanical properties and standards.

How Heat-Treating Affects Metal Components of Heavy Construction Machineries?

Heat treatment is the transferring of heat energy to a material to modify its properties to meet requirements for a specific application. These properties include strength, hardness, wear resistance, ductility, magnetic properties, or elasticity.

Processes of heat treating

• Softening materials
• Hardening metals
• Hardening metal cases
• Softening or hardening a specific area of the material
• Removing stress before or after machining
• Removing stress when bent, formed, or cut
• Change permeability
• Add material resilience

Benefits of Heat Treating Metal Components

Improves machinability and workability

You can apply heat treatment to materials that do not meet specific manufacturing requirements. If you have metal that’s difficult to bend, it can undergo annealing or stress-relieved to soften it. If you want to soften just one part of the material, you can use induction or flame the material. Heat-treating only affects that side of the component.

Improves magnetic properties

If you’re going to use a material for an electronic part of the machinery, you want to reduce its magnetic permeability. By heating it until it reaches its melting point, its atoms will start jumbling around until they lose focus in one direction.

Improves durability and wear resistance

Wear resistance is very important to heavy construction equipment as they work through different types of stress. 

For example, the bucket and teeth of an excavator will go through the stress of digging into compact soil with the possibility of bumping into rocks. It will require the strength of high manganese steels for the bucket and low-alloy steel for the teeth, plus different heat-treating processes. In this case, it should go through quenching and tempering at a low temperature. These procedures will help the bucket last longer and withstand the stress of digging.

Resistance to Corrosion

Corrosion is a culprit to any internal engine and motor. When it starts to build up in the mechanism, it will affect combustion systems and possibly destroy other metal components. That’s why heat treating is necessary to strengthen the coat of metal components to protect it further.

Improve material’s strength 

The reality of heat treating is it can affect the tensile strength, yield strength, and toughness of the equipment. Increasing its strength can reduce toughness and result in brittleness. That is why metal manufacturers should ensure that their released components undergo tensile sample preparation.

It not only goes for metal but for adhesives, sealants, or mastics too.

Safety and the Critical Specifications for Every Machinery Component 

If there is any contribution of heat treating to the heavy construction machine industries, it would be the constant drive to produce safe building machines. Mechanical failure of heavy equipment accounts for many injuries such as amputations and organ damage.

These accidents are avoidable if manufacturers test their produced components to ensure that they meet critical conditions and industry standards. Using an accurate tensile sample preparation machine, they can document the specimen’s breaking point.

Here is where heat treating is critical.

Let us take a piston rod as an example. You will find it in hydraulic cylinders, and it connects to the actual piston to do work. A piston rod goes through frequent movements. Therefore, it has to go through a series of heat treatment processes to improve its wear and corrosion resistance.

The processes include heating, holding, and cooling the metal. These treatments will change a piston rod’s internal structure regardless of the metal used so it can withstand friction, stress, corrosion, and seizure. (This is only one part of a hydraulic system.) The other parts will also require different heat treatment processes to fit their designed application.

Imagine if this part malfunctions because of corrosion or wearing. Safety is compromised.

The Importance of Having Reliable Heavy Construction Machinery Components

The secret to producing reliable construction pieces of machinery is performing critical metal fabrication processes: knowing the appropriate heat treatment, careful execution of the process, having the needed heat treatment facility, plus investing in a tensile sample preparation equipment to ensure compliance with industry standards. 

If you’re a contractor, an operator, or a developer, reliable construction machinery components are essential.

One, they protect the equipment. Two, the operator is safe. Three, you can complete projects without delays. 

Next, you can save tons of money from the length of delays, claims, or lawsuits. 

And the most important thing is safety. Because you are not only protecting the operators, you are also protecting other workers and things around. 

Other than this, heat-treating provides room for innovation and more possibilities.
