Principal Design Features
|
|
This is one of the higher carbon steels used for high hardness in the fully hardened condition. In such condition the steel is more brittle than the lower carbon steels.
|
|
|
Applications
|
|
Applications include springs and cutting tools.
|
|
|
Machinability
|
|
The machinability of this steel suffers because of the high carbon content. It rates at 50% that of the 1112 steel that is considered the 100% machinable base reference.
|
|
|
Forming
|
|
Forming is difficult but may be done by conventional methods.
|
|
|
Welding
|
|
1075 is weldable by all of the welding techniques. However it is important to use pre-heat and post-heat practice as given in approved weld procedure, in order to avoid cracking. Pre-heat at 500 to 600 F and post-heat at 1200 to 1450 F.
|
|
|
Heat Treatment
|
|
This steel may be hardened by heating to 1650 F and oil quenching followed by a tempering treatment.
|
|
|
Forging
|
|
Forge at 2200 F down to 1700 F. It is important to do an annealing operation after forging.
|
|
|
Hot Working
|
|
Hot work at 900 to 200 F.
|
|
|
Cold Working
|
|
Cold working of 1075 is difficult even in the annealed condition. However it may be done by conventional methods but requires more force than for the low carbon steels.
|
|
|
Annealing
|
|
Anneal at 1700 F and slow furnace cool.
|
|
|
Tempering
|
|
Temper, after heating and quenching, at 700 to 1300 F. However this steel is most often used in the fully hardened condition (not tempered) of Rockwell C 55 or so.
|
|
|
Hardening
|
|
Hardens by cold working and heating and quenching.
