What Stainless Steel Materials Are Commonly Used in Selective Laser Melting (SLM)?

SUS316L

SUS316L is one of the most widely used stainless steels in SLM due to its excellent corrosion resistance, weldability, and mechanical stability.

• Tensile strength: ~570 MPa

• Elongation: ~30%

• Applications: Aerospace fittings, marine components, medical housings, and food-grade equipment

SUS630 / 17-4 PH

SUS630 (17-4 PH) is a precipitation-hardened stainless steel that offers high strength and moderate corrosion resistance.

• Tensile strength (H900 condition): ~1,100 MPa

• Yield strength: >1,000 MPa

• Applications: Aerospace brackets, structural mounts, impellers, and high-load mechanical assemblies

SUS15-5 PH

SUS15-5 PH provides improved toughness and better weldability over 17-4 PH, with comparable mechanical strength.

• Tensile strength: ~1,070 MPa

• Better resistance to stress corrosion cracking

• Applications: Pressure housings, aerospace actuators, and precision mechanical parts

SUS304 and SUS304L

SUS304 and SUS304L are general-purpose austenitic stainless steels used where high corrosion resistance and moderate strength are sufficient.

• Tensile strength: ~520 MPa

• Good thermal resistance

• Applications: Industrial housings, kitchen tools, and consumer electronics

SUS410

SUS410 is a martensitic stainless steel offering high hardness and wear resistance after heat treatment.

• Hardness: Up to 50 HRC (after quenching)

• Applications: Pump shafts, tools, valves, and abrasive parts

SUS420

SUS420 is suitable for applications requiring high polishability and edge retention.

• High hardness and moderate corrosion resistance

• Applications: Cutting tools, surgical instruments, dies, and decorative components
