Silver steel bar stockholders and suppliers, delivering to the whole of the UK.
 West Yorkshire Steel are suppliers of precision ground silver steel bar and rod which finds innumerable uses in the tool room and in general engineering. The user can select a size suitable for his purpose, thereby reducing or eliminating the need for grinding or machining the finished part.


The high carbon content aids the hardenability to give considerable wear resistance. The chromium content adds to the strength and hardness characteristics of silver steel. As supplied, however, it is machineable owing to the annealing treatment given in production. Silver steel bar is spheroidised annealed for best machineability, the annealed hardness being in the region of 270 Brinell (Rockwell C 27). On hardening and tempering, a hardness up to 64 Rockwell C can be obtained. Being in the spheroidised condition, it offers maximum response to hardening and the chromium content ensures deep hardening. Silver steel bar is a popular tool room material used in a wide range of applications.


There is, of course, no silver in it, the term ‘silver steel’ is a traditional description. When the grade was fist developed in the early 1900s the addition of chromium (which at the time was becoming increasingly popular as an alloying element in steel) gave the steel a bright 'silver' like finish.

Silver steel can be used in numerous applications including screwdrivers, punches, shafts, axles, pinions, pins, die posts, instrument parts, model parts, taps and drills for mild steel, engravers’ tools, and fine cutters.


Heat uniformly to 770-780°C until heated through. Quench in water. Sizes up to 5/16” dia may be oil hardened from 800-810°C.


Temper according to the purpose for which the parts are required, generally between 150-300°C.

Heat Treatment

Silver steel bar is supplied annealed. When hardening consideration should bee given to heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each silver steel component. Other considerations during the heat treatment process 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 silver steel bar.

Quality Assured Supply

Silver steel bar is supplied in accordance with our ISO 9001 : 2008 registration.
