Why Is Hardox So Tough?

Hardox, also known simply as wear plate, is a wear-resistant sheet steel developed by the Swedish company SSAB in 1974. This steel wears slowly, allowing the equipment used in abrasive applications and aggressive-wear environments to last longer, thereby reducing maintenance needs and costs.

Hardox offers a unique combination of hardness, strength, and toughness. The material’s high strength enables thinner metal sheets to be used, meaning products can be made to be simpler and lighter while still carrying high payloads. Hardox Wear Plate also has good impact resistance, even at low temperatures.

Hardox sheets and plates provide ideal welding and machining properties, simplifying production and repair work. To provide this excellent weldability, Hardox Wear Plate steel is manufactured to have a highly accurate chemical composition. Advanced hardening and post-treatment processes also help imbue it with its unique properties. The combination of high payloads, low maintenance costs, good availability, and long service life allows for overall cost savings while ensuring optimal reliability.

Finally, Hardox’s superior wear performance, crack safety, and deformation resistance provide defense against wear, dents, and cracks. To evaluate these properties, Hardox and ordinary high strength structural plates have been compared through comprehensive drop tests; in one test, weights varied between 330 and 1,800 pounds and were dropped from heights of up to 10 feet. The Hardox steel plate showed only moderate deformation, while the structural steel alternative couldn’t withstand the impact.

Advantages of Hardox

Extremely versatile, Hardox provides critical benefits for various industries. Below are some of the key features discussed above.

  • Superior hardness — Offering excellent wear resistance, Hardox features all-around hardness that doesn’t impact structural performance.
  • Excellent toughness — Hardox is able to resist cracks if subjected to deformation and can withstand heavy blows, allowing it to be easily bent, formed, and welded. Combined with its high yield strength, this durability also allows for the creation of lightweight designs.
  • Consistency — Hardox retains its properties and strength even in severe, harsh conditions — and also during precision bending and forming, as well as precision welding and MIG welding — allowing for predictable, reliable results.
  • Long service life — Hardox can double, or even triple, equipment wear plate service life, optimizing performance while minimizing the risk of damage.

Common Hardox Applications

Hardox’s unique properties make it well suited to a wide range of industries and applications, such as:

  • Construction and demolition — Hardox can be used in various types of construction equipment, from evacuators and demolition tools to fragmentizers, all of which require high reliability and longevity to withstand heavy use and ensure worker safety.
  • Mining — In this safety-critical industry, worker’s equipment — such as mining trucks — must be able to stand up to harsh conditions while maintaining a long lifespan; Hardox provides this reliability, cutting down on repair costs and delays.
  • Military — Hardox Wear Plate provides the protective strength and reliability required in the military industry and is commonly used in the manufacture of armored vehicles.

Strenx (Domex): High Performance, High Strength Steel

What Is Strenx?

Strenx is a high strength, hot-rolled steel sheet also offered by SSAB; the steel is low-alloy and cold-formed. Previously called Domex, this unique material has been rebranded as Strenx.

The Advantages of Strenx

Extremely versatile, Strenx provides critical advantages for various industries. Some of its unique qualities and benefits include:

  • Excellent versatility — This steel has excellent formability and good weldability, meaning it can undergo various manufacturing processes.
  • Reduced production costs — Strenx allows for the manufacture of stronger, higher-quality products that require less steel and welding. This also allows for a lighter-weight product less susceptible to damage, saving money on repair and replacement costs in the long run.

Common Strenx (Domex) Applications

The unique properties of Strenx make it well-suited to a wide range of industries and applications, such as:

  • Automotive — Designers like to keep structural weight low but strength-handling levels high. With Strenx, products made can be simpler and lighter while still carrying higher payloads.
  • Construction and demolition — Strenx can be used in cranes and booms, both of which require high reliability and longevity to withstand heavy use and ensure optimal worker safety.

Welding Capabilities for the Construction Industry

Welding is instrumental to the success of a construction project. Not only is it a handy repair tool for broken and damaged machine parts, it is the mainstay of production supplying any construction endeavour with the required raw materials to progress at the desired pace.

It is undertaken by skilled operators and has to be performed according to pre-defined mandates and a set of compliance rules in order to ensure that the joints are strong and immune to jostling and rust.

WELDING, ITS IMPORTANCE AND IMPERATIVE IN CONSTRUCTION

All kinds of welding rely on generating an arc that is capable of raising the temperature of the parent material to the melting point. It is then fused with a filler metal which by rule of thumb is chosen to be structurally stronger than the original base. Ranging from sub-merged arc to metal active gas to manual metal arc, different welding processes are leveraged at construction sites around the world to serve unique needs. Special ventures in the aerospace and naval industries have progressed to laser arc hybrid welding and electron beam technology.

An operation team manipulating welding equipment must be knowledgeable of the nuances of this technique in order to ensure the integrity of welded joints and thus by association created products. A large scale construction project is only as durable as the quality of its individual components.

Also according to the Consumer Justice Group report, welding tasked to untrained labour is an extremely hazardous proposition. Thousands of injuries occur right on-site because of careless handling of equipment or experimentation by unskilled staff.

SOME BEST PRACTICES TO KEEP IN MIND

As far as possible, complicated welding responsibilities must be left to professionals. Construction projects call for the employment of AWS (American Welding Society) certified welders who are cognizant of the involved risks and capable of handling them expertly.

Especially for the frequently used MIG (Metal Inert Gas) welding:

  • Care should be taken to ensure that welders wear protective gear (including an auto-darkening face shield) to eliminate the risk of contact burns and blisters
  • Cotton is the chosen material because it doesn’t melt like polyester
  • Be on the look-out for splatters of molten metal and grinding sparks which can cause a fire
  • Avoid using galvanized steel as the parent material since it gives off carcinogenic vapours
