BS4659 Steel Specifications
BS4659 tool steel and high speed steel stockholders and suppliers, delivering to the whole of the Middle East. Nifty Alloys LLC are stockholders of a wide range of specifications in round, flat and plate. BS4659 specifications were introduced in 1971. The Iron & Steel Industry Standards Committee working together with tool steel manufacturers and end users standardized the most popular tool steel and high speed specifications used at that time. The grades were grouped in to six types; high speed, hot work, cold work, shock resisting, special purpose and water hardening. Some of the original specification included in BS4659 are now obsolete or have been superceded.

BS4659 Cold Work Tool Steel
Cold work BS4659 grades are stocked in round bar, flat bar and plate which can be bandsaw cut to your requirements.
Cold works BS4659 grades are commonly steels which can be heat treated to a high Rockwell hardness. These specifications are ideally suited for the manufacture of tools working in a surface temperature of no more than 200°C. Cold work grades offer good toughness, high wear resistance, excellent compressive and impact strength and high dimensional stability in heat treatment. Cold work specifications offer wear and toughness characteristics which suit relatively heavy forming and cutting operations at room temperature.

Heat Treatment
When heat treating BS4659 grades consideration should be given to hardening temperatures, including rate of heating, cooling and soaking times which will vary due to factors such as the shape and size of each component. Other considerations during heat treatment include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of BS4659 specifications.
