Here is more content continuing the comparison between 300M, 316L, and 17-4PH stainless steel powders:

Detailed Comparison

300M has higher tensile strength than 316L and lower ductility. It maintains strength up to     600°C better than 316L.

2 316L has the best all-round corrosion resistance followed by 300M and 17-4PH. 300M resists  pitting and crevice corrosion better than 316L.

17-4PH achieves the highest hardness after heat treatment but has lower toughness than 300M and 316L.

300M has higher nickel content than 316L and 17-4PH which improves corrosion resistance. 17-4PH contains copper for precipitation hardening.

300M is used in specialized applications requiring strength at elevated temperatures like aerospace components. 316L is widely used in corrosive environments across industries where high strength is not critical.

17-4PH suits applications requiring high hardness like molds, tooling, and wear-resistant parts for automotive and consumer uses.

300M and 17-4PH powders are more expensive than common 316L powder. 17-4PH is relatively easier to process by laser sintering than 300M.
