Typical Properties of 1045/1018 Keystock
AISI 1045 and AISI 1018 are both common carbon steel grades utilized in manufacturing of keystock. Keystock is used in equipment to prevent movement between the shaft and component and allows certain forces to be released without causing stress. Keystock is used in various mechanical devices including pumps and motors.
Typical Properties of 1144
Carbon 1144 is a medium carbon, resulphurized steel with good free-machining qualities and mechanical properties. Its high sulfur content makes this particular grade have a good machinability rating of 83% as compared to 1212 steel; welding though is difficult. AISI 1144 is a good choice of steel for machined parts requiring better tensile strength and wear resistance than 1045 or 1018.
