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

* 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.
