Wire Cut Shot 1.5mm

Wire Cut Shot 1.5mm is a medium carbon steel abrasive designed for heavy‑duty surface preparation. It is produced by Shandong Haishan Industrial Technology, a manufacturer with an annual production capacity of 100,000 tons and exports to over 50 countries. The product is cut from selected wire and hardened to a controlled hardness range, making it suitable for cleaning thick‑walled steel structures, castings, and forgings where high impact energy and long service life are required.

Technical Specifications

Chemical Composition

Mechanical Properties

Test methods follow GB/T 18838 and SAE J444. Values are confirmed on each production lot.

Performance Characteristics

• High impact energy: The 1.5mm diameter provides greater mass per particle than smaller cut wire shot, generating stronger kinetic energy for removing thick rust, heavy mill scale, and multi‑pass welding slag.
• Good fracture resistance: The selected wire and controlled hardening process produce particles with a tough core, reducing premature breakage during long‑duration blasting.
• Consistent cutting edge: The deformation pearlite microstructure helps maintain sharp edges over extended use, supporting uniform surface profiles.
• Lower dust generation: The thicker cross‑section leads to less particle fragmentation compared to smaller sizes, resulting in reduced dust inside the blasting chamber.

Limitation

Because of its high impact force, this Wire Cut Shot 1.5mm is not suitable for thin sheet metal or precision components. It may cause deformation or excessive surface roughness on thin sections. A technical evaluation is recommended before use on such parts.

Size Selection Guide

The table below provides general recommendations for cut wire shot diameter based on the target application. These are starting points; actual selection may require adjustment based on equipment type, surface profile requirements, and contamination level.

Note: Surface profile values are approximate and depend on blast pressure, standoff distance, and workpiece hardness.

Comparison with Other Abrasives

The following comparison highlights typical differences between 1.5mm steel cut wire shot and other common blast media. Actual results may vary depending on the specific grade and application.

Application Cases

The following examples are based on actual customer feedback. Customer names are withheld for confidentiality, but records are available for verification.

• Shipyard in Shandong: Replaced smaller cut wire shot on a roller conveyor machine for hull plate rust removal. Cleaning time per plate decreased by approximately 20%, and abrasive consumption per square meter dropped by 15% over a two‑month trial.
• Heavy machinery manufacturer: Used in a batch descaling line for large cast steel frames. The product achieved required cleanliness in one pass, eliminating the second blasting stage. Replenishment frequency changed from twice per week to once every ten days.
• Wind tower fabricator: Applied in shot blasting pretreatment of tower sections. The product maintained SA 2.5 surface cleanliness over 300 hours of continuous operation, and no abnormal equipment wear was observed.

Application Scope

Suitable for heavy‑duty cleaning of thick‑walled and large‑scale industrial workpieces. Typical scenarios include:

• Removal of thick, multi‑layer welding slag on large welded steel structures
• Complete descaling and deep rust removal on thick‑walled castings and forgings
• Integrated shot blasting pretreatment of wind turbine towers and heavy construction machinery
• Batch removal of mill scale from heavy steel plate raw material
• Outdoor blasting for heavy rust removal on large ship hull structures

Not suitable for thin sheet metal or precision small parts.

Quality Assurance

Quality control at Haishan covers the entire production chain, from incoming wire inspection to final batch release. Our laboratory is equipped with an Irwin fatigue life tester and a SPECTRO direct‑reading spectrometer. Every batch is tested for chemical composition, hardness, density, and fatigue life before shipping. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications, and products comply with GB/T 18838 and SAE J444. We have exported to more than 50 countries and maintain complete traceability documentation.

 

Operational Notes

• Equipment compatibility: This product works with large roller conveyor wheel blast machines and high‑power open air blast systems. No parameter changes are needed when switching from other cut wire shot of similar size.
• Blast pressure: For optimal performance on heavy rust, a nozzle pressure of 6 - 8 bar (90 - 120 psi) is commonly used. Pressure below this range may reduce cleaning efficiency.
• Dust collection: Regular maintenance of dust collectors is recommended. Although this product generates less dust than smaller sizes, accumulated fine particles should be removed according to the equipment schedule.
• Safety: Operators should wear appropriate protective equipment, including blast suits, gloves, and respiratory protection, as required by local regulations.

Packaging and Storage

The product is normally packed in 25kg bags or 1,000kg bulk bags. All packaging is moisture‑resistant. Store in a dry, covered area away from direct rain. If stored outdoors, keep bags on pallets and covered with tarpaulin. Under proper conditions, the product retains its properties for at least 12 months.

Frequently Asked Questions

How do I know if 1.5mm wire cut shot is the right size for my job?

If you are cleaning thick rust, heavy mill scale, or welding slag on steel sections thicker than 8mm, 1.5mm is often a good starting point. For thinner materials or lighter contamination, a smaller diameter may be more appropriate. Our technical team can help with selection after reviewing your process.

Can this product replace cast steel shot in my machine?

In heavy‑duty descaling applications, 1.5mm cut wire shot can often provide faster cleaning and longer life than cast steel shot of similar hardness. However, because the shape is cylindrical rather than spherical, it may create a slightly rougher surface profile. A trial is recommended before full conversion.

What is the recommended blast pressure?

For heavy rust removal, a nozzle pressure of 6 to 8 bar is typical. For lighter cleaning or on softer materials, lower pressure can be used to reduce surface roughness. Always follow the equipment manufacturer’s recommendations.

Does this product produce less dust than steel grit?

Yes, in most applications. Steel grit is angular and tends to fracture more, generating finer dust. 1.5mm cut wire shot has a tougher core and breaks down more slowly, which reduces dust formation over time.

What documentation is supplied with each shipment?

Each shipment includes a mill test certificate with chemical composition, hardness, and size distribution. Additional reports such as fatigue life or independent third‑party tests are available on request.
