Introduction: The Rise of 904L Powder in Industrial Applications
904L powder—a high-alloy, austenitic stainless steel powder—is quickly becoming a staple in the fields of additive manufacturing, aerospace, marine engineering, and chemical processing. Known for its excellent corrosion resistance, high strength, and weldability, 904L is widely used for producing complex components where longevity and performance are critical.
In B2B sectors, especially among wholesale metal powder distributors, 904L stainless steel powder is in growing demand due to its:
- Outstanding resistance to strong reducing acids (like sulfuric acid)
- High alloy content, including nickel (23–28%) and molybdenum (4–5%)
- Compatibility with advanced manufacturing technologies like Selective Laser Melting (SLM) and Electron Beam Melting (EBM)
Shanghai Truer Technology Co., Ltd. has emerged as a trusted supplier of 3D printing metal powders, including 904L powder, aligning with stringent industry needs for material consistency, purity, and performance.
With the global additive manufacturing market projected to exceed $50 billion by 2030, investing in high-quality powders like 904L is becoming a strategic move for forward-thinking manufacturers and OEMs.
Industrial Applications of 904L Stainless Steel Powder
904L powder is tailored for use in critical applications that demand both mechanical strength and corrosion resistance. Its adoption in powder-based metal 3D printing systems allows engineers to design and fabricate parts that would be difficult or impossible to produce using traditional subtractive manufacturing.
