Stainless Steel 316L Powder / Cr-Ni-Mo-Fe-Mn Alloy Powder 99.9%, 5-20um

Stainless Steel 316L Powder

Introduction

Stainless Steel 316L is a low-carbon version of the standard 316 grade, specifically designed to offer enhanced corrosion resistance, especially in highly corrosive environments. The “L” designation indicates low carbon content, typically below 0.03%, which helps reduce the risk of carbide precipitation during welding, making it an ideal material for applications where the metal will be subjected to high temperatures and corrosive environments.

When transformed into powder form, Stainless Steel 316L Powder is used in additive manufacturing (AM) techniques like Metal 3D Printing or Powder Bed Fusion, as well as in other powder metallurgy applications.

Key Properties of Stainless Steel 316L Powder

Corrosion Resistance: Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride environments.

Strength: High tensile strength, making it durable and resistant to wear.

Formability: Exhibits good formability and can be welded and machined.

Temperature Resistance: Good resistance to high temperatures, making it suitable for extreme thermal applications.

Non-magnetic: Unlike many other stainless steel alloys, 316L remains non-magnetic in most conditions.

Applications

Additive Manufacturing (3D Printing)

Prototyping: 316L powder is widely used in metal 3D printing processes like Selective Laser Melting (SLM) and Direct Metal Laser Sintering (DMLS). It allows for the creation of complex, highly detailed prototypes with excellent mechanical properties and surface finish.

Custom Parts: 3D printing with 316L powder enables the production of custom parts for industries where traditional manufacturing is impractical or costly. Components with intricate internal geometries, such as heat exchangers and medical implants, can be easily produced.

Aerospace and Aviation

Structural Components: 316L stainless steel is commonly used in the aerospace industry to make components that must withstand high stress, harsh environmental conditions, and elevated temperatures. Parts such as brackets, fasteners, and structural elements benefit from its corrosion resistance and strength.

Engine Parts: Some engine components, especially those exposed to extreme heat and stress, may be manufactured using 316L powder due to its high-performance capabilities.
