Thanks
The screw will be use inside of the cockpit(airplane), for some attaching device.
can you be more specific about the process
austenitize at 800c but what time?
oil quench what Temperature of the oil?
temper how long?
Mater if the screw already has a treating process,
(as specs...
The specs for this particular screw says: heat treat: 160 to 180 KSI tensile strength.
I just want to know if this material can get better tensile strength and what are the steps in heat treating to get that.
thanks
May be someone can help me in this:
I have a screw :#10-32 (diameter .19", length 1")hex head, full thread, alloy steel (4340), that according to NAS1801 it has 160 KSI tensile strenght.
Can I heat treating it, to get 300 KSI tensile strenght, if the case what would be the treatments...
I also need a good hardness tester equipment to read HRB,
I am going to work with sheet metal Aluminum alloys from .030" to .125" thickness (7075T6,2024T3,6061T6)
What is the more accurate hardness meter ?
a portable one or a big one traditional
what brand in recomemdable?
Hi swall
one last question
quenching in hot water, means to keep a temperature of the water no more than the room temperature, or there is some value of temperature to keep during quenching?
Thanks
Hi, maybe someone can help me in the next issue:
I tried to achieved 7075-T6 from 7075-T0 ,it is my first time.
The pieces are 0.071" thick.(about 30).Based on technical data I did the following process with the pieces.
1.- (Solution treatment) with the parts (7075-T0) inside the kiln, at...
