Översikt

What is 310S Powder?

310S powder är en low-carbon version of stainless steel 310, specifically designed for environments where high-temperature resistance is crucial. The S in 310S stands for “low carbon”, meaning it has a reduced carbon content compared to its counterpart, making it even more resistant to sensitization och intergranular corrosion at high temperatures.

This powder is primarily used in extreme heat applications, where materials are exposed to oxidation och corrosive atmospheres. In additiv tillverkning, powder metallurgy, och metal injection molding, 310S powder is valued for its ability to maintain structural integrity och prestanda under stress.

Viktiga funktioner

  • Superior Heat Resistance: Handles temperatures up to 1150°C without significant degradation.
  • Oxideringsbeständighet: Performs exceptionally well in oxidizing environments.
  • Motståndskraft mot korrosion: Resists corrosion in both acidic and mildly corrosive settings.
  • Low Carbon Content: Reduces the risk of intergranular corrosion.
  • Versatile Applications: Suitable for additiv tillverkning, powder metallurgy, och svetsning.

Sammansättning och egenskaper

If you’re considering using 310S powder, understanding its kemisk sammansättning och mekaniska egenskaper is crucial. The alloy’s composition drives its prestanda in high-temperature and corrosive environments, making it suitable for industrial uses where standard stainless steels may fail.
