What is music wire spring steel?
Music wire is a versatile, affordable spring steel wire useful in a variety of high-stress applications. It is most frequently used in the manufacturing of spiral springs is but also used for pins, stiffening rods, compression springs and extension springs.
Is a 228 an ASTM?
ASTM A228 is the defining standard for this material. K08500 is the UNS number. It has the highest tensile strength among wrought carbon or non-alloy steels. In addition, it has a fairly low ductility and a moderately low thermal conductivity….Music Wire Spring.

| Shear Modulus c GPa | 11600 80.0 |
Why do assassins use piano wire?
The Garrote wire is used to strangle one’s opponent or cut into the neck, slicing through the carotid arteries. Because it is easily concealable, silent, and deadly, it is often used for assassinations in situations when a gun is not a suitable option.
Why is piano wire so strong?
How strong is piano wire? In fact, each string on a piano is tightened to between around 75kg and 100kg of tension, so one string on a piano has more tension than a whole guitar. All of this combined means the total tension of all the strings in a piano is around 20 tonnes, which is why a cast iron frame is needed.
What is ASTM A313?
ASTM A313-18 has a scope that provides information on austenitic, austenitic-ferritic, and age-hardenable stainless steel round spring wire meant especially for the manufacture of springs. ASTM E527 Practice for Numbering Metals and Alloys in the Unified Numbering System (UNS)
What is music wire used for?
Aside from its use in pianos, this wire is most frequently bent into springs for high-tension applications because it can bear repeated heavy loads. (For example, music wire is often used in spring-loaded windows.) It is also used for fishing lures, cheese slicers, crafts and hobbies, surgical tools, and so on.
What’s the difference between steel and spring steel?
While the materials also differ in manganese content, carbon content is the major differentiator here. Known as a high carbon steel, blue tempered spring steel is harder, less bendable, and has a higher degree of spring back.
Can a wire cut you in half?
The answer to that one is actually yes. See my previous post for the physics and mathematics details, but here’s the bottom line. Given some reasonable assumptions about carbon nanotubes, a wire with a diameter of about 0.2 millimeters could cut someone in half just by running into it.
Can wire cut through bone?
A Gigli saw is a flexible wire saw used by surgeons for bone cutting. A Gigli saw is used mainly for amputation, where the bones have to be smoothly cut at the level of amputation.
What are the special properties of music wire?
Special Properties: Music Wire is cold drawn, and it has a high and uniform tensile. Music Wire is the toughest and most widely used of all spring materials for small springs. It has the highest tensile strength and can withstand higher stresses under repeated loading than any other spring material.
Why is music wire used for small springs?
Music Wire is cold drawn, and it has a high and uniform tensile. Music Wire is the toughest and most widely used of all spring materials for small springs. It has the highest tensile strength and can withstand higher stresses under repeated loading than any other spring material.
Which is the toughest spring wire to use?
These materials are not satisfactory for high or low temperatures or for shock or impact loading. Music Wire is cold drawn, and it has a high and uniform tensile. Music Wire is the toughest and most widely used of all spring materials for small springs.
What’s the maximum operating temperature for music wire?
Applications under cold or hot temperature extremes (maximum recommended operating temperature is 250˚F) Madison Steel is a global supplier of steel related raw material products, including music wire, PC strand, recycled scrap steel and more.
