ASTM A519 Mechanical Seamless Tubes

e case. This will have little effect on case hardness and willreduce the risk of grinding cracks.
Hardening
Heat to 840 oC - 875 oC, hold until temperature is uniformthroughout the section, soak for 10 - 15 minutes per 25 mm section,and quench in oil, water, or polymer as required.
*Temper immediately while still hand warm.
Nitriding
4140 hardened and tempered bar can also be successfully nitrided,giving a surface hardness of up to Rc 60. Nitriding is carried outat 490 oC - 530 oC, followed by slow cooling (no quench) reducingthe problem of distortion. Parts can therefore be machined to nearfinal size, leaving a grinding allowance only. The tensile strengthof the core is usually not affected since the nitriding temperaturerange is generally below the original tempering temperatureemployed.
Normalizing
Heat to 870 oC - 900 oC, hold until temperature is uniformthroughout the section, soak for 10 - 15 minutes and cool in stillair.
Stress Relieving
Heat to 680 oC - 700 oC, hold until temperature is uniformthroughout the section, soak for 1 hour per 25 mm section, and coolin still air.
Tempering
Re-heat to 550 oC - 700 oC as required, hold until temperature isuniform throughout the section, soak for 1 hour per 25 mm ofsection, and cool in still air.
Notes on Heat Treatment
Heating temperatures, rate of heating and soaking times will varydue to factors such as work piece size/shape also furnace typeemployed, quenching medium and work piece transfer facilitiesetc..

Machining
4140 in the hardened and tempered as supplied condition has good tovery good machinability and operations such as sawing, turning,drilling, broaching, hobbing, milling and tapping can be carriedout satisfactoraly using machine manufacturers recommendations forsuitable tool type - feeds and speeds.
