- The sulfide layer is relatively soft, improving initial compatibility during friction and exhibiting solid lubrication effects. - As a result, the sulfurized layer enhances compatibility and shows good seizure resistance and galling resistance. - For gears that require quiet operation, a reduction in gear noise can be achieved. - Gas soft nitriding of austenitic stainless steel is also possible.
