Shri Chatanya Sales Agencies operates from India and currently lists five active products in its catalogue. The catalogue covers a mix of refractory, gemstone, and metal‑related items, specifically AZS refractory, cubic zirconia, spent activated alumina, used alumina balls (HS code 6903.20, material Aluminum Oxide Al2O3), and scrap graphite (HS code 2504.10, material Natural Graphite Scrap with carbon content 80‑95%).
The supplier is classified as an imported tier with a harbor trust rating, indicating a moderate level of verification. All product entries are presented without additional certifications, so buyers should verify compliance with relevant standards for each material before procurement.
The AZS refractory is a high‑temperature ceramic material commonly used in steel ladles and furnaces; industry grades are typically classified by silica‑alumina ratio and refractory density, with grades such as AZS‑10 to AZS‑40 used in the market. Cubic zirconia is a synthetic gemstone, usually supplied in sizes from 1 mm to 10 mm and graded by clarity (CI) and color tolerance, with standard cut shapes including round, oval, and pear. Spent activated alumina is a regenerated adsorbent often measured by its surface area (m²/g) and moisture content, and is reused in gas drying or water purification processes. Used alumina balls, identified under HS 6903.20, are ceramic grinding media typically sized 2 mm to 15 mm, with hardness values around 15 GPa and alumina purity of 99 %. Scrap graphite, under HS 2504.10, is carbon scrap ranging from 80 % to 95 % carbon, supplied in bulk bags or bulk containers and used for electrode production or refractory mixes.
Typical grades are identified by the silica‑alumina ratio, such as AZS‑10, AZS‑20, AZS‑30, and AZS‑40, each offering increasing refractoriness and density suitable for steel‑making furnaces.
Buyers usually ask for a gemological laboratory report confirming cut, size, clarity (CI grade), and color tolerance, as well as compliance with ISO 18323 for synthetic gemstone safety.
Key parameters include BET surface area (typically 200‑300 m²/g), moisture content below 2 %, and regeneration efficiency expressed as a percentage of original adsorption capacity.
Commercially supplied used alumina balls are commonly sized between 2 mm and 15 mm in diameter, with a typical hardness of 15 GPa and alumina purity of 99 %.
Scrap graphite imports usually contain 80 % to 95 % carbon, with ash content below 5 % and moisture under 1 % for bulk shipments.
