Hammer crusherLiner plates in HARDOX 450 or HARDOX 500.
Anvils in HARDOX 500 or HARDOX 550. Can be problems with replacing the original anvils. They are often cast and have a complicated design.
Hammers replacing cast material can have lamellar structure in HARDOX 550 or HARDOX 600. Huge potential. Risks for fractures during process and tempering during fabrication. Contact your application engineer.
GratingsGratings can be made of HARDOX 450 or HARDOX 500.
To beware of at fabrication.
The plates can get tempered from cutting and welding.
The bars can twist during the attachment process.
