S1 Tool Steel
S1 tool steel stockholders and suppliers, delivering to the whole of the UK. West Yorkshire Steel are stockholders and suppliers of S1 tool steel round bar. S1 is an alloy shock-resisting tool steel for both hot and cold work applications. The tungsten content of this tool steel grade confers fatigue resistance, the chromium content gives depth of hardness and resistance to abrasion. S1 tool steel is suitable for cold work tools subject to heavy shock and uneven loading; for example, press tools used for punching heavy gauge material, shear blades, nut blanking tools, perforating and piercing punches. This steel is also used with great success for chisels and punches required for heavy work on hard and tough materials. S1 tool steel is resistant to heat checking. It is suitable for hot work applications where high fatigue strength in combination with medium hot hardness is desirable. Tools made from this tool steel may be water cooled in service with little risk of cracking.
