304L stainless steel powder (UNS S30403) is a corrosion-resistant material that exhibits good property stability below 1000°F. This low-carbon variant of the 304 grade provides the advantages of austenitic stainless steel, making it an excellent choice for various manufacturing processes.
304L Stainless Steel Advantages
304L stainless steel powder offers superior corrosion resistance compared to 303 grade, making it a preferred option for components that may not undergo extensive machining operations. A major benefit of this material is the balance between performance and cost-effectiveness, providing an economical solution without compromising on quality.
304L Stainless Steel Powder Applications
SS 304L powder enables precise fabrication of complex geometries and components. Its versatility makes it suitable for Powder Metallurgy (P/M) applications such as lock hardware, appliance parts, and automotive exhaust system components. Other applications include:
