When higher degrees of dimensional accuracy and straightness are required, we recommend the use of PRECISION SHAFTING, which is produced by grinding and polishing.
Stock Lengths: 12' Approx.
Applications
N/A This material is used where greater strength is required than can be obtained from the lower carbon steels. It responds to heat treatment, and a wide range of properties can be obtained. Applications include shafts, machinery parts, bolts, pinions, gears, etc. |
Mechanical Properties
N/A
The following values are average and may be considered as representative:
|
Machinability
N/A Machinability rating is approximately 64% based on 1212 as 100%. Average surface cutting speed is between 95 and 105 feet per minute. |
Weldability
N/A Due to higher carbon content, this material is not readily welded. With thin sections and flexible design, gas or arc welding may be used without preheating, but in joints over 1/2" to 3/4" thick preheating is necessary. To develop equivalent strength in a weld, a low alloy filler is recommended. Stress relieving after welding is also recommended. The grade of welding rod to be used depends on thickness of section, design, service requirement, etc. |
Hardening
N/A This steel is essentially water-hardening, but it may be quenched in oil. The recommended quenching temperatures are 1550°F for water and 1575°F for oil. A wide range of mechanical properties can be obtained by tempering at different temperatures between 700°F and 1300°F. Tempering in the range from 500°F to 700°F should be avoided. |
