By combining the benefits of through hardening and case hardening, the raw material becomes thoroughly hard and the surface develops an even harder, wear-resistant layer.
The advantages can be seen in riveted chains where the chain speeds are high and wear-resistance needs to be particularly good..
Resistance to wear and tear brings cost savings..
Of all chain manufacturers, we have probably studied and tested this method in practice the most.
By far the best hardening method for heavy-duty chains that demand hard compression resistance.
The through hardened bush has an unsurpassed capacity to withstand pressure from the socket without cracking. It is mostly used for big, welded chains, M224 and larger.
The multifrequency induction hardening system, developed and registered by Lapua Chains.
The hardening is performed on company premises in Lapua under company's own supervision
The inner surface remains unhardened
> for targets with lighter use. A low-cost and efficient hardening method
