Tongcheng manages every stage from alloy raw materials and atomized powder production to sieving and blending, sampling and testing, packaging and release, and batch traceability.
Engineering focus: Quality control for stainless steel powder
Review the material, particle-size, process and validation factors that matter for this application.
Clear production input is the starting point for batch management.
Critical process changes are reflected in the powder state.
Correspond delivery batches to inspection and order information.
Production process quality control
Starting from raw materials and proportions, the key links of melting, atomization, powder collection, sieving, mixing and packaging are managed.
Powder testing items
With particle size analysis as the core, we focus on chemical composition, impurities, density, flowability and related items required by customers based on products and processes.
Batch and shipment management
Connect powder products to production and customer usage through sampling, retention, batch identification, packaging information and shipping records.
Powder testing, quality control and batch traceability
Enter quality topics from particle size, composition, interstitial elements, density, flow, sintering results and batch records.
Stainless Steel Powder D10, D50, D90 Particle Size Analysis
Use D10, D50, D90 and the full particle-size distribution curve to compare the fine fraction, median size, coarse tail and distribution width of stainless steel powders.

Tongcheng’s quality management covers alloy raw materials, atomization, powder sieving, sampling and testing, packaging and release, and corrective action for deviations.
Explore topic →03Stainless steel powder batch traceabilityStainless steel powder batch traceability and production management
Tongcheng connects raw materials, powder production, sieving and blending, sampling and testing, packaging, shipping and customer feedback through batch numbers.
Explore topic →04Chemical composition of stainless steel powderConfirmation of chemical composition and grade of stainless steel powder
The chemical composition determines the identity and performance basis of the material; when purchasing, the grade standard, product specification range, typical values and specific batch testing values should be distinguished.
Explore topic →05Stainless Steel Powder Oxygen Nitrogen CarbonWhy do you need to pay attention to the oxygen, nitrogen and carbon content?
Oxygen, nitrogen and carbon are related to the powder surface, debinding, sintering atmosphere, phase composition and final performance, and should be evaluated according to the specific grade, process and specifications of both parties.
Explore topic →06Apparent and tap densityapparent density and tapped density of stainless steel powder
Apparent density describes how powder packs when freely poured under specified conditions; tap density describes packing after vibration. Interpret both with particle size, morphology and test method.

Hall and Carney funnels address metal powders with different flow behavior. Interpret their results separately from actual powder feeding, feedstock rheology and die or cavity filling.
Explore topic →08Sintered Density and Dimensional ShrinkageSintering density, shrinkage and part performance evaluation
The sintering density and dimensional shrinkage need to be evaluated under the specified conditions of forming, debinding, sintering and heat treatment, and cannot be compared apart from the specimen and process status.
