Product Philosophy - Durability Redefined

In corrosive environments, iron contamination and oxidation of traditional steel grit remain industry pain points. Shengxiang Guanghe Stainless Steel Grit innovates from the metallurgical stage, using Argon Oxygen Decarburization to precisely control the chromium-nickel ratio, ensuring each particle has a uniform austenitic structure. Unique surface passivation enriches the chromium content on the surface to over 18%, forming a self-repairing chromium oxide protective film that quickly reforms even if scratched.

Materials Science Deep Analysis

Corrosion Protection Mechanism
Prevents intergranular corrosion by controlling chromium carbide precipitation at austenite grain boundaries. Utilizes solution treatment to completely dissolve carbides, combined with rapid cooling to maintain a supersaturated solid solution state. A unique electropolishing process reduces surface roughness to Ra 0.4μm, fundamentally eliminating corrosion initiation points.

Microstructure Control
Introduces grain refinement technology, controlling austenite grain size to grade 8 or higher. Adjusts hardness appropriately while ensuring corrosion resistance through deformation-induced martensitic transformation. Precisely controlled cold working degree achieves optimal performance balance.

Hygiene & Safety Assurance
Developed sterile production processes, including UV disinfection, alcohol rinsing, and vacuum packaging. Established a complete microbial detection system ensuring products meet medical-grade hygiene standards. Each batch undergoes biocompatibility testing.

Industry Application Evidence

01.

Food Machinery Manufacturer Verification Report

"In a dairy equipment renovation project, equipment inner walls treated with Shengxiang Guanghe Stainless Steel Grit showed no signs of corrosion after 30 days of immersion in 3% sodium chloride solution. The product fully meets FDA food contact material standards, helping customers obtain EU EC1935/2004 certification."

Marine Engineering Contractor Practice Feedback

"In deep-sea oil platform valve treatment, traditional carbon steel grit required replacement after just 2 weeks, while stainless steel grit maintained good performance for 3 months of continuous use. Calculations show that although the initial investment is higher, the total cost over the service life is reduced by 60%."

FAQ

Q: What is the performance difference between stainless steel grit and ordinary steel grit in humid environments?

A: In an environment with 80% relative humidity, ordinary steel grit shows significant rust after 8 hours of use, with cutting efficiency dropping by 40%. Under the same conditions, stainless steel grit shows no rust after 200 hours of continuous use, with stable performance maintained. This is determined by the fundamental difference in materials.

Q: What special treatments are required for use in the food and pharmaceutical industries?

A: We provide medical-grade specific models, processed through special deionized water cleaning, alcohol purification, and vacuum packaging. Each batch comes with a microbial test report, ensuring compliance with GMP standards. Material certification documents are also provided to facilitate customer equipment registration.

Q: How to treat the inner surfaces of workpieces with special shapes?

A: We developed specialized small-grit stainless steel grit series (G200-G400), combined with dedicated internal bore blasting equipment, capable of treating deep holes and internal cavities with diameters above 6mm. Process guidance is also provided to help optimize jet parameters.
