630 stainless steel, also known as 17-4 PH or 17-4 Precipitation Hardening steel, is a martensitic stainless steel containing approximately 15–17% chromium and 3–5% nickel. Due to its precipitation-hardening characteristics, it has excellent corrosion resistance and superior strength at high hardening depths. It can be used in applications requiring good mechanical properties at elevated temperatures up to 600°F (316°C).
630 stainless steel, also known as 17-4PH or 630 Martensitic Stainless Steel, boasts of chromium, nickel, and copper constitutions, with little molybdenum and niobium. The unique composition of this stainless steel gives it excellent strength and toughness, which makes it highly desirable in the industries mentioned earlier. Specifically, the copper and nickel in the steel give it superior toughness, while the chromium content provides excellent corrosion resistance properties.

Its high strength and superior mechanical and physical properties make it ideal for applications that require high strength, toughness, and corrosion resistance alongside high-temperature resistance. It finds its application in aerospace, chemical processing, power generation, and automotive industries. In the automotive industry, 630 stainless steel is commonly used for engine parts, transmission gearboxes, and hydraulic lines.
Regarding corrosion resistance, 630 stainless steel is highly corrosion-resistant, thanks to its high chromium and copper content. Nevertheless, its corrosion resistance properties are enhanced when heat-treated using the appropriate heat treatment process. Speaking of heat treatments like quenching, tempering, and annealing all have different effects on the properties of 630 stainless steel.
As for machining and welding considerations, 630 stainless steel can be challenging to machine and weld adequately. This is a result of the steel hardening during the machining process. However, this can be mitigated using special techniques like proper coolant or lubrication, slow speeds, and sharp tools.
On the other hand, welding 630 stainless steel requires preheating and post-weld heat treatment to prevent cracking and maintain its mechanical and physical properties.
In conclusion, the properties of 630 stainless steel make it an ideal material for high-strength applications. Its copper, nickel, chromium, and molybdenum content gives it superior mechanical and physical properties and impressive corrosion resistance, toughness, and strength. That said, it is up to manufacturers and industries to utilize 630 stainless steel to its fullest potential, considering heat treatments, machining, and welding considerations. By doing so, they can reap the benefits of this type of stainless steel.
