High Carbon Steel Wire Cut Shot

Shandong Haishan Industrial Technology produces high carbon steel cut wire shot for automated continuous blasting lines that require low abrasive consumption and stable performance. The raw material is high carbon steel wire with a carbon content between 0.70% and 0.95%. After integral quenching and tempering, the finished product maintains a hardness range of HRC 48 to 55. The resulting microstructure is tempered martensite, which provides a dense particle structure with high resistance to impact fatigue. This gives the product a significantly longer service life compared to conventional low carbon cut wire shot.

Technical Specifications

Chemical Composition

Mechanical Properties

All values are obtained from routine batch testing in accordance with GB/T 18838 and SAE J444. Hardness and chemical composition are verified on every production lot.

Performance Characteristics

• Hardness and cleaning efficiency: The HRC 48 to 55 hardness provides strong impact and cutting action. In comparative blasting tests, rust and welding slag removal speed is measurably faster than low carbon cut wire shot.
• Wear and fracture resistance: Internal laboratory fatigue testing shows a particle fracture rate reduction of more than 50% under standard blast conditions, which extends replacement intervals and reduces downtime for refilling.
• Angularity retention: Under 24‑hour continuous operation, cutting edges remain sharp longer, avoiding premature rounding and maintaining consistent surface profile.
• Total cost of ownership: Although the unit price is higher than low carbon wire shot, the longer cycle life and lower consumption lead to lower overall abrasive cost in high‑volume production environments.
• Compatibility with automated lines: Designed for closed‑loop wheel blast machines and automatic air blast systems used in unmanned, non‑stop production.

Limitations

Under extreme impact conditions with very high blast intensity, the base material toughness is slightly lower than that of low carbon steel cut wire shot. In such cases, the anti‑fracture buffering capacity may be reduced. A technical evaluation is recommended before selection for unusually severe applications.

Application Cases

The following examples illustrate typical use scenarios. Customer names are withheld for confidentiality, but test data and operational feedback are on file.

• Large steel structure manufacturer in East China: Replaced low carbon cut wire shot on a 24‑hour continuous rust removal line for heavy steel beams. Abrasive consumption per ton of processed steel decreased by approximately 35% over a three‑month evaluation period.
• Automotive casting supplier: Used in an automated descaling line for cast iron parts. The replacement frequency dropped from every 3 days to every 9 days, with no measurable change in surface profile or cleanliness.
• Wind power component manufacturer: Applied in a shot peening line for gearbox housings. The product maintained consistent intensity over 500 hours of continuous operation, meeting the required Almen arc height specifications.

Application Scope

Suitable for all‑weather automated shot blasting and sandblasting mass production, particularly where abrasive consumption is closely monitored and long‑term cost reduction is a priority. Typical scenarios include:

• 24‑hour non‑stop automated closed‑loop shot blasting lines
• High‑volume continuous rust removal pretreatment for heavy steel structures
• Fully automatic batch descaling for cast steel and iron parts
• Long‑duration shot peening and strengthening lines for components
• Standardized industrial workshops with strict limits on abrasive usage

Quality Assurance

Haishan operates an in‑house laboratory equipped with a fatigue life tester (Irwin, USA) and a direct‑reading spectrometer (SPECTRO, Germany). Chemical composition, hardness, density, and fatigue life are tested on every production batch. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications, and all products comply with GB/T 18838 and SAE J444. Certificates and test reports are available upon request. Haishan exports to over 50 countries and has supplied abrasives for numerous large‑scale industrial projects worldwide.
