Introduction

In the surface preparation industry, achieving a pristine, contamination-free finish on non-ferrous metals requires abrasives that are as precise as they are durable. Stainless Steel Cut Wire has emerged as the superior choice for shot blasting and peening applications where ferrous contamination cannot be tolerated. Unlike cast abrasives, this engineered media offers a combination of longevity, cleanliness, and surface brightness that significantly enhances operational efficiency .

What is Stainless Steel Cut Wire?

Stainless steel cut wire is manufactured by drawing high-quality stainless steel wire to a precise diameter and then cutting it into cylindrical pellets. In its standard form, the length of each pellet is equal to the diameter of the wire. These pellets can be used "as cut" for aggressive finishing or "conditioned" (rounded) to produce a G3 spherical shape ideal for shot peening .

Key Physical Properties

• Shape: Cylindrical (as cut) or Round (conditioned)

• Density: $7.6-7.8{\text{g/cm}}^3$

• Bulk Density: Approximately $4400{\text{kg/m}}^3$

• Hardness: Ranges from $308$ to $509\text{HV}$ depending on material and temper .

Primary Applications

Due to its unique properties, stainless steel cut wire is the media of choice for specialized applications:

1. Non-Ferrous Metal Cleaning: Ideal for aluminum castings, zinc die-castings, and copper alloys. It effectively removes burrs and flash without embedding ferrous particles that can cause discoloration or corrosion later .

2. Architectural Finishing: Produces a bright, lustrous, "orange peel" finish on stainless steel fabrications and architectural components, enhancing the natural metal color .

3. Shot Peening: The conditioned (spherical) variant is used to impart compressive stresses on critical non-ferrous aerospace or automotive components, improving fatigue life without risk of contamination .

4. Deburring: Cleans delicate parts with precision, ensuring a dust-free and bright surface .

Specifications and Material Grades

Selecting the right grade is critical for performance. The most common stainless steel grades used are AISI 304, AISI 430, and AISI 410. Each offers a different balance of hardness, corrosion resistance, and cost.

Available Sizes (Diameter)

The diameter of the wire determines the intensity of the impact and the resulting surface profile. Common stock sizes range from very fine to coarse:

Standard Diameter Range: $0.3\text{mm}$ to $2.5\text{mm}$

Common Stock Sizes:

• 0.3 mm (CW12): For fine finishing and delicate parts.

• 0.6 mm (CW23): General purpose deburring.

• 1.0 mm (CW41): Heavy cleaning and medium peening.

• 1.5 mm (SSCW 1.5): Coarse surface profiling .

Advantages Over Cast Steel Shot

• Longer Life: Because the wire is solid and worked rather than cast, it resists fracturing and maintains its shape longer than cast abrasives, reducing consumption and dust .

• No Ferrous Contamination: Essential for maintaining the corrosion resistance of stainless steel workpieces and the appearance of aluminum.

• Consistent Performance: Uniform density and hardness ensure repeatable results from batch to batch .

Conclusion

For manufacturers seeking to improve the quality of their surface finishing while eliminating the risk of contamination, Stainless Steel Cut Wire offers an unbeatable combination of durability and performance. Whether you require the hardness of AISI 304 for peening or the economy of AISI 430 for cleaning, this media provides the consistent, high-quality finish that modern industry demands.
