Overview of Stainless Steel 304L Spherical Powder

Stainless steel 304L is one of the most popular and widely used austenitic stainless steels. The “L” in 304L stands for “low carbon,” meaning the alloy contains a maximum of 0.03% carbon. The lower carbon content makes it more resistant to sensitization during welding or extreme heating, which can prevent issues like corrosion or weakness at joints.

When this alloy is processed into Bột hình cầu, it becomes highly suitable for sản xuất phụ gia and metal injection molding. The spherical shape of the powder particles is crucial for ensuring better flowability, packing density, Và uniformity during printing or molding processes. This results in stronger, more precise end products with fewer defects — an absolute necessity when manufacturing high-performance parts.
