What do you use to quench 5160 steel?
The short version: Heat the steel to non-magnetic any way you can (815 C / 1500 F) No hold time required, just get the entire blade to this temperature. QUICKLY quench in luke warm Canola oil (oil is 30-50 C / 86 F-122F)
What is the Rockwell hardness of 5160 steel?
Mechanical Properties
| Properties | Metric | Imperial |
|---|---|---|
| Elongation at break (in 50mm) | 17.20% | 17.20% |
| Hardness, Brinell | 197 | 197 |
| Hardness, Knoop (converted from Brinell hardness) | 219 | 219 |
| Hardness, Rockwell B (converted from Brinell hardness) | 92 | 92 |
Does 5160 steel hold an edge?
5160 steel Edge retention This means it forms low carbide volumes and can’t hold its sharpness for long and you’ll need to sharpen your 5160 spring steel knife regularly, especially if you’re cutting hard media. That said, 5160 will hold an edge better than most of the steels out there.
Can you quench 5160 in canola oil?
Canola is a bit fast for 5160. It will definitely get super hard but you run the risk of cracking the blade in the quench.
Do you need to temper 5160?
5160 has very good toughness with a heat treatment using an austenitizing temperature of 1500-1525°F and tempered at 375-400°F. That results in 58.5-59.5 Rc and very high toughness when heat treated with a cryo step.
Can you weld 5160 steel?
Since 5160 has some chrome, it is usually considered to be not very ideal for forge welding. Also, higher carbon contents tend to help, and 0.60% C is not especially high. Therefore, it would generally be recommended to weld on a mild steel chunk for the tang.
How strong is 5160 steel?
5160 steel is exceptionally tough and resilient….Table 1: Summary of mechanical properties for 6063 aluminum alloy.
| Mechanical Properties | Metric Value | English Value |
|---|---|---|
| Ultimate Tensile Strength | 958 MPa | 139000 psi |
| Tensile Yield Strength | 530 MPa | 76900 psi |
| Bulk Modulus | 160 GPa | 23200 ksi |
| Modulus of Elasticity | 205 GPa | 29700 ksi |
Can I quench spring steel in water?
Don’t try to hold it at heat, it does not benefit from soaking. Always quench 5160 in oil. It will crack in water, period.
What is in quenching oil?
They are composed of base mineral or petroleum oils, and often contain polar lubricants like fats, vegetable oils, and esters, as well as extreme pressure additives such as chlorine, sulfur, and phosphorus. Straight oils provide the best lubrication and the poorest cooling characteristics among quenching fluids.
What should the temperature be to heat treat 5160?
5160 has very good toughness with a heat treatment using an austenitizing temperature of 1500-1525°F and tempered at 375-400°F. That results in 58.5-59.5 Rc and very high toughness when heat treated with a cryo step.
Why is H13 steel used in hot work?
Because of its excellent combination of high toughness and resistance to thermal fatigue cracking (also known as heat checking) H13 is used for more hot work tooling applications than any other tool steel. Because of its high toughness and very good stability in heat treatment, H13 is also used in a variety of cold work tooling applications.
How to heat treat 5160-optimizing steel Nerds?
While the heat treatments we performed may apply to a broader range of 5160 given a different prior forging and annealing, the heat treatment is most likely to give the same result when forged, normalized, and annealed in the same way. Normalization = 1600°F for 20 minutes followed by a plate quench
Why does 5160 steel have a flat hardness?
Because of the drops in toughness with low or high tempering temperatures, and the relatively flat hardness with different austenitizing temperatures, 5160 does not appear to be very flexible in terms of its possible property combinations.
