Import Bearing Steel Grit G18 — Buy in wholesale FOB from Supplier in China

Bearing Steel Grit G18 from Belong Blasting Technology Co., Ltd. is a coarse abrasive media classified specifically for heavy-duty surface cleaning and descaling operations. Manufactured from GCr15 high-carbon chromium bearing steel, equivalent to SAE 52100, the product is crushed directly from bearing steel cut-offs rather than from cast shot. This G18 grade corresponds to a nominal particle size range where approximately 85% is retained on笔下的a 1.0 mm screen with limited fines passing 0.5 mm, making it suitable for aggressive removal of heavy mill scale, rust, and existing coatings from steel structures. The controlled carbon and chromium composition provides hardness typically in the 58-65 HRC range with enhanced resistance to particle fracture under repeated impact.

The material's metallurgical structure derives from the fine pearlitic matrix of forged bearing steel, containing approximately 0.95-1.05% carbon and 1.30-1.65% chromium with tightly controlled sulfur and phosphorus levels below 0.025% each. This alloy content produces chromium carbide precipitates that improve wear resistance compared to plain carbon steel abrasives. The angular particle morphology generated by mechanical crushing creates sharp cutting edges that produce surface profiles of 75-125 microns on blast-cleaned substrates, appropriate for heavy protective coating systems in marine and infrastructure applications. Standard density is 4.0-4.5 g/cm³, with bulk packaging typically in 25 kg bags or tonne-scale flexible intermediate bulk containers.

Primary buyers operate in steel structure fabrication, foundry cleaning, and shipbuilding sectors where rapid material removal and recyclable media life are critical economic factors. The G18 size is particularly valued for open nozzle blasting of large weldments and ship hull sections where coarse anchor patterns improve coating adhesion on thick steel plate. Shipyards and offshore fabricators in Southeast Asia represent a significant demand segment. Import considerations include verifying the supplier's quality control documentation for hardness consistency and particle shape regularity, as irregular fracture patterns can cause uneven surface profiles and premature dusting in reclamation systems.

Belong Blasting Technology Co., Ltd. is headquartered at No 8 Industry Park, Wafang, Dalian 116225, Liaoning Province, China. The supplier maintains harbor trust tier status, indicating verified business registration without additional third-party certification or inspection verification. The response rate is recorded at 0.00% with zero average response hours, which may reflect limited platform engagement rather than operational status. No specific year of establishment, employee count, revenue figures, or facility size is disclosed in the available profile data. The Dalian location in Liaoning Province provides access to Dalian Port, a major northern Chinese container and bulk cargo gateway with established routes to Northeast Asian and Pacific markets.

The company's product focus centers on blasting abrasives with particular emphasis on bearing steel grit derived from GCr15 material. The detailed product description indicates technical familiarity with metallurgical specifications and industry applications, suggesting either direct manufacturing involvement or close mill relationships. No ISO certifications, environmental management systems, or specific quality accreditations are confirmed in the profile. Buyers should independently verify production capabilities, including whether the company operates crushing and sizing equipment or sources from a dedicated processing partner. The industry park location in Wafang suggests potential clustering with metalworking and heavy industrial enterprises in the broader Dalian economic zone.
