Which stainless steels and metals are used for watches

In watchmaking, we differentiate between steel for watch parts (encapsulated) and the watch case with its watch strap (outside)

The following steel and metal grades are used for the watch parts:
For clock works, axles and other small rotating parts with wear requirements:
Typical hardenable carbon steels, non-corrosive: LAW 100 Pb and LAW 100 X (magnetic)
Typical hardenable martensitic carbon steels, corrosion-resistant: Chronifer Labor M-Plus (1.4197) and Chronifer M-15 X (magnetic)

Amagnetic stainless spring steel with limited wear resistance: Phynox KL
Spring steel with limited wear resistance, magnetic: Durimphy
For watch parts without wear requirement: Brass, Arcap, CuBe2, Declafor 1015

The following steel qualities and Non-Precious metals are used for watch cases, outside parts of and metal watch straps:
For watch cases: Chronifer Spezial 35, Chronifer Spezial 35 P, 1.4441 Implant, Chronifer Spezial 904L, Titan Grade 5, Titan Grade 2, Cobalt BC
For watch crowns: Chronifer Special KL 1.4427, Chronifer Special 35, Chronifer Special 35 P, Aisi 316 L Décolletage, Phynox KL
For watch straps: Chronifer Spezial 35, Chronifer Spezial 35 P, Chronifer Special 904L 1.4441 Implant, Phynox, Titan Grade 5.

Watch making steel is available on stock as bars / rods.

Properties of watchmaking grade stainless steel

The steel used for the manufacture of the precise watch parts should have a fine structure, for the clock works mostly hardenable, for the watch cases high corrosion-resistant and wear-resistant. Chromium is added to improve the rust and wear resistance of the steel.
The company Klein has developed two special watch steel grades: these are the LAW 100 X® and the Chronifer® M-15 X. Both have been produced by the same powder metallurgic process in order to obtain an extreme fine structure. The smaller the parts are, the more important is the fine structure of the steel, in order to meet today's requirements of polishing ability. Especially in the area of the "haut de gamme" (high-price-segment) watch.

L. Klein SA is a dependable distributor of different kinds of watchmaking steel. In Switzerland a local delivery service is provided, but we also supply even smallest quantities to entire Europe and worldwide. Thanks to many years of experience and professional knowledge, excellent multilingual customer support and service is offered.
The assortment consists of steel with special requirements like narrow tolerances and small diameters as bars, coils and round profiles.
