Metric Silver Steel 333mm Long

Coventry Grinders offer silver steel in a wide range of metric diameters. Silver Steel is a high carbon bright steel ground to a very close tolerance. It is supplied in an annealed condition but because of the high carbon and chromium content it can achieve high hardness levels. Silver steel is a versatile product that can be used in many engineering applications. Some non-standard sizes can be found in stock (e.g. 1mm, 5/64″) and we are able to produce bespoke sizes to order on – just get in touch!

Silver Steel name derives from its appearance, due to its extremely fine surface finish and chrome content when ground. Unfortunately it does not contain silver. We have over 20 years experience in supply and manufacture of Silver Steel so if you have any questions regarding this product do not hesitate to ask.

Silver Steel  Typical Chemical Composition

Harnening

Heat slowly to 760-800 C using the upper end of the temperature range for a lower carbon contents and lower end of temperature range for higher carbon contents.  Austenitize until the temperature is uniform. Quench into well agitated water.

The approximate quench hardness is 65 – 68 Rc.

Tempering

Temper immediately after hardening preferably before the tool reaches room temperature. Temper for a minimum of 1 hour at temperatures between 180-350 C dependent upon the final harness required.
