High Carbon Wire

High carbon spring steels are the most commonly used of all materials. Try to use these materials in preference to others because they are least expensive, readily available, easy worked, and most popular. These materials are not satisfactory for high or low temperatures or for shock or impact loading.

Oil Tempered
ATSM A 229
Cold drawn and heat treated before fabrication.
General purpose spring wire
Carbon Valve
ATSM A 230

Good surface condition and uniform tensile.

Alloy Steel Wire

The alloy spring steels have a definite place in the field of spring materials. Try to use these materials, particularly for conditions involving high stress and for applications where shock or impact loading occurs. Alloy spring steels can also withstand higher and lower temperatures than the high-carbon steels and are obtainable in either the annealed or pre-tempered conditions.

Chrome Vanadium
Chrome Vanadium
Cold drawn and heat treated before fabrication. Used for shock loads and moderately elevated temperatures.
Chrome Silicon
ASTM A401
Cold drawn and heat treated before fabrication. Used for shock loads and moderately elevated temperatures. (Mid-West Spring recommends that Chrome Silicon never be electro-plated.)

Stainless Steel Wire

The use of stainless steels has increased considerably in recent years. Several new compositions are now available to withstand corrosion. All of these materials can be used for high temperatures up to 650° F.

ASI 302-304
ATSM 313
Cold drawn. General purpose corrosion and heat resistant. Magnetic in spring temper.
ASI 316
ASTM A313
Cold drawn. Heat resistant and better corrosion resistant than 302. Magnetic in spring temper.
17-7 PH
ASTM A313 (631)
Cold drawn & precipitation hardened after fabrication. High strength and general purpose corrosion resistance. Slightly magnetic in spring temper.

Non-Ferrous Alloy Wire

Copper-based alloys are important spring materials because of their good electrical properties combined with their excellent resistance to corrosion. Although these materials are more expensive than the high-carbon and alloy steels, they nevertheless are frequently used in electrical components and in subzero temperatures. All copperbased alloys are drawn to the American wire gage (same as Brown & Sharpe gage) and are magnetic.

Phosphor Bronze
Grade A ASTM B159
Cold drawn. Good corrosion resistance and for electrical conductivity.
Beryllium Cooper
ASTM B197
Cold drawn and may be mill hardened before fabrication, good corrosion resistance and electrical conductivity. High physicals.
Monel 400
AMS 7233
Cold drawn. Good corrosion resistance at moderately elevated temperatures.
Monel K500
QQ-N-286
Excellent corrosion resistance at moderately elevated temperatures.

High Temperature Alloy Wire

Nickel-based alloys are especially useful spring materials to combat corrosion and to withstand both elevated and below-zero temperature applications. Their magnetic characteristics are important for such devices as gyroscopes, chronoscopes and indicating instruments. These materials have high electrical resistance and should not be used for conductors of electric current.

Flat High-Carbon Spring Steels

Flat high-carbon Spring Steels General. Although several types of thin flat strip are available for specific applications in watches, clocks and certain instruments only two types are readily available. These two compositions are used for over 95% of all applications requiring flat high-carbon strip. Although these materials are frequently plated, sections under 0.015 in. having carbon content over 0.85 with hardness over Rockwell C47 are highly susceptible to hydrogen-embrittlement even though special plating and heating operations are employed.
