SHEFFIELD™ KEYSTOCK – Cold Drawn, Plus Tolerance

Sheffield Keystock is manufactured to very strict standards. Uniformity and surface finish are controlled through a drawing process that increases physical properties. This process is also known as strain hardening.

Sheffield Keystock is furnished to a plus tolerance, precision "key-fit". Maintenance and machine repair personnel understand that loose keystock bars will not hold in place. Slop in the key-fit will diminish service life.

Sheffield Keystock is offered in 12 foot lengths. Most suppliers of keystock, only offer material in 12" and 36" lengths.

Do not confuse Sheffield Keystock with commercial "cold roll" that is usually only 1018 mild steel.

Sheffield Keystock offers the following advantages that are not commonly found in heavy industry.

• Sharp square corners
• Fine grain structure
• Medium carbon content
• May be heat treated to elevated hardness
• Precision "plus tolerance"
• 12 foot standard lengths
