The commonly used materials in MIM metal powder injection molding process mainly include stainless steel, soft magnetic materials, carbon steel, tool steel, high-specific-gravity alloy steel, 17-4PH stainless steel and SUS630 stainless steel. What's the difference between 17-4PH stainless steel and SUS630 stainless steel?

17-4PH stainless steel and SUS630 stainless steel are different naming methods for the same material. 17-4PH stainless steel is a high-strength stainless steel alloy with the material number S17400, while SUS630 is the JIS standard naming for this material in Japan.

This stainless steel alloy has excellent mechanical properties and corrosion resistance, and is often used to manufacture parts and components that require high strength and good corrosion resistance. Here are some characteristics and applications of 17-4PH/SUS630 stainless steel:

1. High Strength: 17-4PH/SUS630 stainless steel has high strength and can maintain its mechanical properties in high-temperature and high-pressure environments.

2. Good Corrosion Resistance: This stainless steel alloy has good corrosion resistance and can resist most common corrosive media such as acids, alkalis, and salts.

3. Magnetism: 17-4PH/SUS630 stainless steel is an iron-based alloy and therefore has some magnetic properties.

4. Heat Treatment Performance: 17-4PH/SUS630 stainless steel can be heat-treated to adjust its mechanical properties, such as strength and toughness.

This stainless steel alloy is widely used in aerospace, petrochemical, nuclear energy, food processing, and medical device industries, among others, for manufacturing valves, bearings, pumps, gears, sanitary fixtures, etc. Its high strength, excellent corrosion resistance, and heat treatment performance make it an ideal choice for many industrial applications. Whether it's 17-4PH stainless steel or SUS630 stainless steel, they both refer to the same material, only with different naming conventions.
