Hardox® tubes get their strength from high hardness and solid toughness. Hardness helps fight wear from rocks, metal, soil, and other rough materials. The tube can handle impact without breaking because it is tough. Hardness goes up as the grade number goes up. This makes the wear life longer, but it might make it less flexible. This is a simple and clear look at each level.
Hardox® 400 Tubes
Hardox® 400 tubes offer steady strength with good toughness. Their hardness level is moderate, so they can handle impact and wear together. They are easy to cut, weld, and form. This makes them suitable for frames, brackets, and general wear parts. These tubes work well in jobs that do not face extreme abrasion but still need strong and reliable steel.
Hardox® 500 Tubes
Hardox® 500 tubes bring higher hardness than Hardox® 400. They keep good toughness while offering longer wear life. This balance makes them fit for many heavy-duty jobs. They work well in tools and machines that run daily under rough loads. These tubes last longer in chutes, buckets, and structural parts of mining and construction tools.
Hardox® 550 Tubes
Hardox® 550 tubes reach a higher hardness range. They resist wear better than Hardox® 500 tubes. These tubes are used where friction, dust, and hard particles cause fast damage. They offer longer service life in abrasive zones. They fit work like stone handling, ore processing, and heavy recycling machines.
Hardox® 600 Tubes
Hardox® 600 tubes are known for their very high hardness. They are built for places where extreme abrasion is normal. These tubes face constant wear but still hold their strength. They are used where other steels fail fast. Hardox® 600 tubes are ideal for high-impact and high-friction jobs such as heavy mining, crushing, and large-scale earthmoving.
| Grade | Hardness (HBW) | Wear Resistance | Toughness | Best Use Case |
| Hardox® 400 Tubes | ~370–430 | Good | High | Moderate wear tasks |
| Hardox® 500 Tubes | ~470–530 | Very Good | Good | Heavy-duty work |
| Hardox® 550 Tubes | ~525–575 | Excellent | Medium | High abrasion |
| Hardox® 600 Tubes | ~570–640 | Highest | Lower | Extreme abrasion |
Key Applications of Hardox® Tubes
Hardox® tubes are used across many industries. Their wear strength and long life make them a smart pick for tough jobs.
Mining & Quarrying
Large mining tools face stones, dust, and impact all day. Hardox® tubes help support these machines. They are used in chutes, hoppers, conveyor frames, and crushing parts. Their high hardness slows down wear and reduces repair time. Workers can rely on these tubes to run longer between service stops.
Construction & Earthmoving
When lifting, pushing, and digging, construction machines have to deal with a lot of force. Hardox® tubes keep these tools strong even when they are under a lot of stress. They are used in loader arms, support frames, and buckets that wear out. Their strength keeps machines from moving and breaks less often on the job site.
Material Handling & Recycling
Recycling plants deal with metal scraps, broken parts, stones, and glass. These materials cause deep wear on steel. Hardox® tubes help protect the moving parts in chutes, crushers, and shredders. Their long wear life lowers maintenance costs and keeps machines running without long delays.
Agriculture & Forestry
Farm and forest tools deal with soil, sand, wood, and stones. Hardox® tubes help these machines last longer in rough outdoor work. They are used in harvesting units, chopping tools, grain flow systems, and feed hoppers. Farmers and operators get more life from their tools with fewer part replacements.
Advantages of Hardox® Tubes
Hardox® tubes offer many practical benefits that make them dependable in harsh working conditions. Their mix of hardness and toughness helps machines run longer without damage. Here is a closer look at why they stand out.
Exceptional wear resistance
Hardox® tubes hold up well against friction, impact, and constant material flow. They resist grinding and scraping better than standard steel. This means less surface loss and longer working hours before replacement.
Long service life in tough jobs
Because these tubes fight wear so well, they last longer in places where dirt, stone, and metal cause serious damage. This helps companies avoid repeated part changes and reduces waste on repairs.
High strength-to-weight ratio
Hardox® tubes offer high strength without adding extra weight. This makes machines lighter and more efficient. Designers can create strong frames and moving parts without bulky material.
Less downtime and fewer repairs
Hardox® tubes keep their shape and do not wear thin quickly. This reduces sudden failures and keeps equipment running. Fewer stoppages mean better productivity and smoother workflow.
Good for welding and fabrication
Even with their high hardness, Hardox® tubes can be welded and cut with proper steps. This makes them flexible for builders, workshop teams, and plant engineers who need custom shapes and sizes.
Reliable for structural and wear parts
These tubes stay stable under load and vibration. They are a safe choice for frames, supports, and wear sections that face daily stress. Why Choose Kamlesh Metal Alloy Hardox® Tubes
