Home Cold Rolled Steel C1045 Cold Rolled Steel C1045 Grade Description: Cold Rolled Steel C1045 is a medium carbon steel allowing higher strength properties than 1018. A wide range of properties can be obtained. Typical Applications: Shafts Machinery parts Bolts Pinions Gears Analysis: C – .43/.50 Mn – .60/.90 P – .04 Max. S – .05 Max. Mechanical Properties: (following are minimum properties based on typical 1” bar) Typical Mechanical Properties**: Tensile Strength (PSI) 82,000 Yield Point (PSI) 45,000 Elongation*** 16 Brinell Hardness 162 * Chemical Analysis will vary on each heat number ** Tests based on Cold Drawn Round Bar – All values are minimum values and are representative. *** % in 2” Machinability: 64% based on 1212 as 100%. Surface Cutting Speed: 95-105 ft/min. Weldability: Fair. With thin sections and flexible design, gas or arc welding may be used without preheating except in joints over 1/2“ to 3/4” thick where preheating is necessary. For equivalent strength in a weld a low alloy filler is recommended. Stress relieving after is recommended. Grade of welding rod to be used depends on thickness of section, design, service requirement, etc. Hardening: Essentially water hardened (1550º F) although can be quenched in oil (1575º F). Wide range of mechanical properties obtained by tempering between 700º F to 1300º F. Avoid tempering between 500º F and 700º F.
