Översikt

What is 304L Powder?

304L powder är en low-carbon version av stainless steel 304, one of the most commonly used grades of stainless steel. The “L” i 304L stands for low carbon, which means it contains a maximum of 0.03% carbon. This lower carbon content makes 304L powder more resistant to sensitization (grain boundary carbide precipitation), a phenomenon that can lead to intergranular corrosion after svetsning.

In powder form, 304L stainless steel är idealisk för additiv tillverkning, formsprutning av metall, och pulvermetallurgi processes. Its korrosionsbeständighet, Formbarhet, och svetsbarhet make it a versatile material for a wide range of industries, including fordonsindustrin, Medicinsk, food processing, och kemisk bearbetning.

Viktiga funktioner

• Motståndskraft mot korrosion: Fungerar bra i mildly corrosive miljöer.
• Low Carbon Content: Reduces the risk of intergranular corrosion after welding.
• Utmärkt svetsbarhet: Can be welded without post-weld annealing.
• Mångsidig: Suitable for a variety of production techniques, inklusive 3D-utskrifter, pulvermetallurgi, och formsprutning av metall.
• God formbarhet: Easily formed into a variety of complex shapes.
