The steel, and how we build with it
We build with SSAB wear and structural steels and weld to EN ISO 3834-2. The wear steel resists abrasion and the structural steel lets the attachment weigh less, so the machine has more capacity left for the load.
Hardox® wear plate: protection against abrasion
The areas that wear fastest are built from SSAB Hardox® wear plate.
Hardox® 400
The general grade for bucket shells and liners, for moderate wear.
Hardox® 450
Harder than Hardox® 400, so it dents less and wears more slowly.
Hardox® 500
For quarry and mining work, where sliding wear is what wears a part out.
Hardox® HiTuf
For thick load-bearing wear parts that have to take hard impacts without cracking.
Strenx structural steel: strength with less weight
Strenx high-strength structural steel lets us build an attachment lighter for the same strength. Lower attachment dead weight leaves more of the carrier's rated capacity available for payload.
Strenx 700
High-strength steel for load-bearing parts such as attachment bodies and brackets. Thinner plate carries the same load.
Strenx 900
For the most highly loaded joints. The higher strength allows thinner sections there, which matters most on long-reach equipment.
Strenx 1100
The highest yield strength of the three grades, for parts where the load is high and weight must be kept low.
Engineering and fabrication
EN ISO 3834-2 · EN 1090-1
The EN ISO 3834-2 certificate, issued by UDT-CERT, covers comprehensive welding quality requirements. The EN 1090-1 factory-production-control certificate for structural steel components was issued by UDT-CERT, notified body 1433.
Material Traceability
Every plate is traceable to its heat, so we can show that the steel in your attachment has the properties the drawing asks for.
