Application

1: 304 stainless steel powder is a core material in 3D printing, suitable for technologies like SLM and EBM. With high sphericity and good fluidity, it enables the production of complex and lightweight components. It is used for aerospace engine brackets, automotive gears, etc. Powders with a particle size of 30-50μm are commonly used, while ultra-fine powders (<30μm) are for high-precision medical implants.
2: 304 stainless steel powder has a performance-cost advantage in powder metallurgy and MIM. Powder metallurgy can mass-produce hardware like locks and home appliance parts. MIM, relying on low-oxygen spherical powder, achieves high-density sintering, producing parts with good toughness and precision for automotive and electronic precision components.
3: 304 stainless steel powder is a key raw material for thermal spraying and hardfacing, forming a dense protective layer. It is used for corrosion protection of petrochemical pipelines, marine engineering steel structures, etc., and for mechanical mold repair to quickly restore worn surface performance and reduce equipment replacement costs.

4: 304 stainless steel powder can be sintered into filters for fluid filtration in food, beverage, and chemical industries. It can also be mixed into plastics as a metal additive to enhance strength, wear resistance, and thermal conductivity. It is also used in equipment manufacturing for special fields like nuclear energy and marine engineering.
