Hardox® 600

With Hardox^® 600, you don’t have to sacrifice wear resistance for impact strength. Thanks to its properties, this steel can withstand impacts that often lead to fracture or destruction of other wear parts made in white iron chromium castings, manganese castings, bimetals or ceramics. Hardox^® 600 has an impact toughness that can make it more durable than those materials. It also successfully fights sliding wear. Want to learn if Hardox^® 600 is right for your particular application?

• Makes a good alternative to conventional AR steel or Hardox^® steel with lower hardness grades, manganese steel castings or ceramics
• Parts made with this high-strength and hard steel are strong and durable
• Get thinner yet higher-performing wear liner packages
• A long and predictable service life leads to lower maintenance costs and increases productivity
• Long-lasting and productive equipment has environmental benefits, since it uses less steel and energy over time
• Widely available plates, shorter delivery time compared to manganese steel castings
• Workshop benefits: Comes already through-hardened, is machineable and weldable, no preheating needed, standard workshop methods can be used
• Spare parts can be quickly and easily fabricated

• Mining, quarrying and earthmoving utilize Hardox^® 600 for wear liners exposed to sliding wear, chute liners, conveyor skirt boards, screens, silo and pan feeder liners.
• Hardox^® 600 is used for industrial process equipment such as crusher knives, hammers, discs, blades, jaw crusher cheek plates, liner plates, deflector plates, shredder knives, cone crushers, ball mill liners, concrete molds, vertical and horizontal shaft impactor discs and liners, and knives for flaker rings.
• Cement, concrete, steel and energy plants use chutes, hopper liners, vertical rolling mill liners, feeder liners and screens, baffle plates, split scrapers and guide vanes in Hardox^® 600.
• Forestry equipment in Hardox^® 600 is for example harvester feed rollers, log washer paddles and shredder knives.

A little extra hardness can go a long way. At the high end on the hardness scale for our Hardox^® range of grades, Hardox^® 600 can give your equipment the extra edge in service life in applications that take a beating. Hardox^® 600 has a yield strength around 1650 MPa, much higher than for standard structural steels like S355 steel, which has a yield strength of about 355 MPa.

If you upgrade from a lower Hardox^® grade like Hardox^® 500, you can gain up to a 50% longer equipment service life. When upgrading from a 400 HBW AR steel, you can get a service life up to 4 times longer. If you do opt for using a lower-grade material, remember that you might be looking at higher production, replacement and downtime costs in the long run.

With the Hardox^® WearCalc app from SSAB, you can determine the increase in service life of equipment for different Hardox^® grades compared to mild steel. Calculations include a lot of abrasive materials such as granite, clinker, coal, iron ore, limestone, sand, glass and household waste containing metal.
