• 100% of chosen lots of steel are quality-controlled
The best quality at the best price
Each month we test hundreds of disks for their hardness and overall quality, to ensure that the best disks at the best price are delivered to you.
TESTING OF COMPETING BRAND'S STEEL :
Fine martensite structure before tempering.
Presence of sulfures in linear inclusions. Presence of ferrite in metallurgical structure.
Quenched structure :(martensite partially tempered) Less than 1% of ferrite. No linear sulfures
Fragile quenched structure : Non-tempered martensite.
Presence of sulfures in linear inclusions.
3 TESTS ALLOW US TO TEST OUR DISKS :
Hardness test Ball test
8 years of research resulted in the creation of this new disc : a disc with hardness increased to 200kg/mm² for still better performance in the field.
