Import Custom Cf-8m 316 Stainless Steel Pump Body — Buy in Bulk from Supplier in China

The Custom CF-8m 316 Stainless Steel Pump Body is a precision-cast component designed for industrial fluid handling systems. It measures 300mm by 180mm by 120mm and weighs 30kg gross. The material conforms to ASTM A351 CF-8M, a low-carbon molybdenum-modified austenitic stainless steel grade, offering enhanced corrosion resistance over standard CF-8. This casting is manufactured using investment casting and silica sol processes to achieve tight dimensional control and surface finish suitable for high-pressure applications.

The base alloy contains approximately 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, meeting standard ASTM specifications for 316 stainless steel. Surface treatments include sandblasting for texture control, polishing to reduce surface roughness, and heat treatment to relieve casting stresses. Typical mechanical properties include a minimum tensile strength of 515 MPa and a yield strength of at least 205 MPa, consistent with industry norms for cast 316 stainless components. Foreign matter content is controlled through spectrographic analysis and metallurgical inspection.

This pump body is used in food processing, medical equipment, mining machinery, and vacuum systems where hygiene and chemical resistance are critical. Buyers include OEMs in Europe and Asia that require certified castings for replacement or custom integration. Packaging is custom wooden crate with internal foam padding. Lead time for first orders is typically 4 to 6 weeks, subject to tooling readiness. MOQ is negotiable for machining-ready components, and samples are provided free of charge if a subsequent order is placed.

Hongtuo Mechanical Casting Co., Ltd operates from Guangzhou, Guangdong, with a foundry facility in the Shigang Shiji Industrial Area. The company specializes in custom precision castings for industrial equipment and holds ISO9001:2008 certification. Their production capabilities include investment casting, sand casting, and silica sol processes with in-house testing for chemical composition and mechanical properties. The listing does not state annual output, employee count, or export volume.

The supplier accepts sample requests without charge if followed by a production order and accommodates small batch orders for machined parts, indicating flexibility for niche buyers. They emphasize ODM/OEM collaboration and claim experience serving European markets, though no client names or contract volumes are disclosed. There is no mention of export licenses, third-party audits, or recent certifications beyond ISO9001:2008. Response rate and average reply time are not tracked in the system, suggesting limited digital engagement infrastructure.
