Can I heat spring steel?
If you want to bend it you need to heat it until it glows red and it loses its hardness. Then it slowly cools and it doesn’t harden again and you can treat it the same way you would normal steel.
Key features of spring steel wire
- Resilience — It is highly resilient, and can return to its original shape after being bent or stretched.
- Strength and durability — Spring steel can support heavy loads without breaking, and is particularly good at withstanding cyclical loads that would fatigue other alloys.
- Elasticity — It can be formed, shaped, as well as post-heat treated without losing its shape.
Is spring steel the same as music wire?
Music wire is made of spring wire. They are all iron alloy wires. Because spring wire has many grades, the yield strength is also different. For example, music wire contains a higher proportion of chromium, grade ASTM A228, so it has better tensile strength. In addition to piano wire, its applications include spring clips, antennas, S-shaped forks, and clutch plates.
What is the maximum temperature for spring steel?
Using stainless spring steels has ballooned in recent years. Several new compositions are now available to withstand corrosion. We can use these materials for high temperatures up to 650°F.

Can you bend spring steel?
if the cross section is small and the steel used is not hardened too much it can be bent cold as is. Trial and error is needed here.
if this is not the case then the steel can be either annealed and bent cold or heated to red hot and then bent hot.
following this process the steel will need to be quenched and then tempered.
the exact process is dependent on the grade of steel being used, as different steels require different heating temperatures and quenching mediums, as well as different tempering profiles.
Does spring steel lose strength when heated?
Excessive heat exposure can cause serious damage to technical springs, then leading to loss of function or failure. For example:
– Springs made from steel alloys may lose tensile strength after prolonged high-temperature exposure.
– Elastomeric materials used for some types of seals degrade over time at elevated temperatures
– The lifespan of electrical control switches utilizing small metallic springs decreases significantly at higher ambient temperatures due to metal fatigue.
Is spring steel the same as carbon steel?
| Spring steel | VS | Carbon steel |
| 0.5% – 1.0% | Carbon content | 0.05%-2.0% |
| Excellent elasticity and resilience | Mechanical properties | Good strength and ductility |
| Corrosion resistance | Corrosion resistance | Susceptible to corrosion |
| Structural components, mechanical parts, and other general applications | Applications | Specially used for springs, wires, and other parts requiring high elasticity and resilience |

How long does spring steel last?
When it comes to stainless steel springs, how long can you expect them to last? If your spring broke suddenly, you might wonder about this.
You may think a spring will always return to its original shape as long as it’s never stretched too far. However, many factors affect spring life.
The spring can break if it is subjected to more force than it was designed to handle.
The extension spring can be irreparably damaged if it is extended too far. So keeping oil-tempered spring deflection to a maximum of 25% of their total length will prolong their life.
Here is Spring Wire’s life expectancy on average:
- Standard Cycle Springs: 10,000 cycles
- High Cycle Springs: 25,000 cycles
- Highest Cycle Springs: 50,000 cycles

Is spring steel good for cutting?
1075 Blue Temper Spring Steel is a versatile steel that isn’t just for springs, clamps, and coils. Therefore, we often use it in blade-making as well.
It’s able to hold its edge well and is receptive to sharpening.
Why do We call it spring steel?
Spring steel is an assembly of various steel materials, we use it to make springs, especially in automotive and industrial suspension applications.
The high elastic limit is achieved by a special alloy containing silicon, manganese, besides, chromium, vanadium, molybdenum, and nickel.
The tensile strength is obtained by a final heat treatment.

How to Extend The Life of Your Steel Springs?
1. At first, keep it lubricated continuously and choose a mild, non-corrosive lubricant.
2. Then, keep the environment dry.
3. At last, be careful not to come into direct contact with other metals.
Then balance the spring wire every few years to prevent it from tensile fatigue.
These steps will help extend the life of your spring wire.
Generally, a spring will not break within a year. If it breaks, it may be due to substandard materials, defects, aging, or improper use and installation. Therefore, it is important to choose a reputable factory that provides a warranty for the spring and obtains ISO certification.
