In support of the Swiss watch industry's ambition to avoid lead in watches, Sandvik has developed a new, lead-free steel grade for fine mechanical components.

Following practical tests in the Swiss watch industry, Sandvik Finemac™ free-cutting steel has proven to be a successful replacement for 20AP, the previous standard grade for fine mechanical parts.

Free-cutting steel containing lead has long been the standard alternative for machining of fine mechanical parts. In anticipation of more stringent EU legislation and increasingly expensive scrap handling of materials containing lead, the Swiss watch industry approached Sandvik with a desire to find a fully functional lead-free alternative to steel grade 20AP.

The new lead-free grade, Sandvik Finemac™, has been tried and approved by Swiss watch companies. The properties of Sandvik Finemac™ are equally good, and in some aspects better, than 20AP. A positive feature is the wider temperature and time range available for hardening operations that will simplify processing and reduce scrapping.
