Bearing Steel Wire Cut Shot

Shandong Haishan Industrial Technology produces bearing steel cut wire shot from new high purity bearing steel wire. No recycled scrap steel is added during production. Sulfur and phosphorus content is kept within controlled limits to reduce inclusions. After cutting, the shot passes through a two stage grading process to remove irregular particles and fine dust. The result is a clean, consistent abrasive suitable for precision surface preparation.

Hardness is held between HRC 42 and 47, which is selected to relieve machining stress on hardened components without changing critical dimensions. The product releases very little dust during blasting and resists rust formation during storage. These properties help keep bearing cavities, oil passages, and close fitting gaps free from contamination.

Key Product Features

Controlled Raw Material

The steel wire comes from qualified bearing steel mills and is not mixed with recycled scrap. Each shipment includes a material certificate that records the heat number and chemical composition. This allows buyers to trace the raw material back to its source and verify that impurity levels meet specification.

Two Stage Grading and Low Dust

After cutting, the shot is graded twice. The first pass removes oversize and irregular shapes. The second pass removes fine particles and dust. This reduces the amount of airborne dust during blasting and helps keep the work area cleaner. Lower dust levels also mean less frequent filter replacement on dust collection equipment.

Stable Hardness for Stress Relief

Hardness is controlled within the range of HRC 42 to 47. This range is effective for stress relief on hardened steel parts without aggressive cutting action. The uniform microstructure helps produce even surface coverage during shot peening. For bearing rings, gears, and precision shafts, this reduces the risk of dimensional change or surface damage.

Recommended Applications

• Shot peening of bearing inner and outer rings
• Stress relief for precision gears and shafts
• Surface preparation of medical metal parts
• Clean blasting of close tolerance transmission components

This product is not intended for heavy rust removal or rough surface preparation. For those jobs, standard cast steel shot or steel grit offers a more economical choice.

Procurement Notes

Before ordering, it is helpful to know your blast machine model, workpiece material, and required surface finish. Our engineers can recommend a suitable shot size and hardness range based on this information. Free samples are available for testing on your own equipment.

The unit price of this product is higher than standard cast steel shot or recycled cut wire shot. In precision applications, however, the reduction in rework, scrap, and cleaning time often offsets the higher material cost. We suggest comparing total cost per finished part rather than price per kilogram.

We keep common sizes in stock for fast delivery. Each batch is tested for chemical composition, hardness, and density. A material certificate and physical property report are included with every shipment.

Frequently Asked Questions

Q1: Is the raw material really free of recycled steel?

A: Yes. This product is made from new bearing steel wire sourced from qualified steel mills. We do not add recycled scrap. The material certificate for each batch identifies the heat number, so the chemical composition can be traced back to the original steel source.

Q2: Will this shot damage the surface of precision parts?

A: The hardness is controlled between HRC 42 and 47. This level is designed to relieve residual stress without aggressive cutting. The shot is also graded twice to remove irregular shapes, which further reduces the chance of surface scratching or uneven peening.

Q3: Does the product rust in storage?

A: It has anti oxidation properties and does not form rust scale under normal indoor storage conditions. We still recommend keeping the material in a dry, covered area. Even with minor humidity exposure, rust formation is much lower than with ordinary carbon steel shot.

Q4: Can I use this for general structural steel cleaning?

A: It is not recommended. The high purity raw material and two stage grading process make this product more expensive than standard abrasives. For structural steel rust removal, cast steel shot or grit provides adequate performance at a lower cost.
