BS1407 Silver Steel
Silver Steel is a versatile high carbon tool steel which is ground and polished to very close tolerances. It is so called because of its highly polished appearance created by the extremely fine surface finish. The high carbon content of this BS1407 Silver Steel means that it can be hardened to give considerable wear resistance and the chromium content increases its strength and hardenability. It is readily machinable and supplied in the spheroidised annealed condition. The material as delivered, shall have a hardness of not more than 285HB when measured in accordance with BS240.
All our Silver Steel has "State of the Art Precision Laser Marking" to ensure fully traceability. This unique identification covers every individual or cut length. (excludes 2mm - 5.5mm and 1 1/16" - 7/32")
Customer applications for Silver Steel:
Heat slowly to 760 - 800°C using the upper end of the temperature range for 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 to 69 Rc.
Silver Steel 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 hardness required.
