316L Stainless Steel Powder: Low-Carbon Alloy for Corrosion Resistance and Versatility
Overview:
316L stainless steel powder is a low-carbon variant of 316 stainless steel, offering enhanced corrosion resistance and weldability. This alloy is widely used in marine, medical, and food processing industries due to its excellent mechanical properties and resistance to pitting and crevice corrosion. The spherical powder form ensures superior flowability and precision, making it ideal for additive manufacturing and powder metallurgy.
What is 316L Stainless Steel Powder?
316L is an austenitic stainless steel alloy with a reduced carbon content compared to standard 316. This modification minimizes carbide precipitation during welding, improving its resistance to intergranular corrosion. Its balanced composition and mechanical properties make it a versatile choice for various demanding applications.
