  • AISI 302/304
  • AISI 316
  • 17-7 PH

Description

Music Wire / High-Carbon Steel

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

-Music Wire – ASTM A 228

  • Cold drawn. High and uniform tensile. High quality springs and wire forms.

-Hard Drawn – ASTM A 227

  • Cold drawn. Average stress applications. Lower cost springs and wire forms.

-High Tensile – Hard Drawn – ASTM A 679

  • Cold drawn. Higher quality springs and wire forms.

-Oil Tempered – ASTM A 229

  • Cold drawn and heat treated before fabrication, General purpose spring wire.

-Carbon Valve – ASTM A 230

  • Cold drawn and heat treated before fabrication. Suitable for cyclic applications

Description

Stainless Steel Spring Wire

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

-AISI 302/304   ASTM A 313 Stainless Steel 

-Cold drawn, general purpose, corrosion and heat resistant. Magnetic in spring temper

– AISI 316   ASTM A 313 Stainless Steel

Cold drawn. Heat resistant and better corrosion resistance than 302. Magnetic in spring temper.

– 17-7 PH Stainless Steel ASTM 313 (631)

Cold drawn & precipitation hardened after fabrication. High strength and general purpose corrosion resistance. Slightly magnetic in spring temper.


Copper Alloys

  • Phosphor Bronze
  • Beryllium Copper
  • Monel 400
  • Monel K 500

Description

Copper Alloy Spring Wire

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

– Phosphor Bronze Grade A   ASTM B 159

Cold drawn. Good corrosion resistance and electrical conductivity.

– Beryllium Copper – ASTM B 197

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 temperature.

Monel K 500 – QQ-N-286 

Excellent corrosion resistance at moderately elevated temperature.


Alloy Steels

  • Chrome Vanadium
  • Chrome Silicon

Description

Alloy Still Wire

The alloy spring steels have a definite place in the field of spring materials, particularly for conditions involving high stress and for applications where shock or impact loading occurs. Alloy spring steels also can withstand higher and lower temperatures than the high-carbon steels and are obtainable in either the annealed or pre tempered conditions. Note: These materials are not regularly stocked in a wide variety of sizes.

-Chrome Vanadium – ASTM A 231

  • Cold drawn and heat treated before fabrication. Used for shock loads and moderately elevated temperature.

-Chrome Silicon – ASTM A 401

  • Cold drawn and heat treated before fabrication. Used for shock loads and moderately elevated temperature.

Nickel Alloys

  • A 286 Alloy
  • Inconel 600
  • Inconel 718
  • Inconel 750

Description

Nickel Alloy High Temperature Spring Wire

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

– A 286 Nickel Alloy

Cold drawn and precipitation hardened after fabrication. Good corrosion resistance at elevated temperature.

– Inconel 600 – QQ-W-390

Cold drawn. Good corrosion resistance at elevated temperature.

– Inconel 718 Nickel Alloy

Cold drawn and precipitation hardened after fabrication. Good corrosion resistance at elevated temperature.

-Inconel X-750 Nickel Alloy AMS 5698,5699

Cold drawn and precipitation hardened after fabrication. Good corrosion resistance at elevated temperature.
