Stainless Steel 630, also commonly referred to as 17-4 PH, is a martensitic stainless steel grade used in a wide range of industrial applications thanks to its corrosion resistance, high strength and the ability to tailor its properties through heat treatment.

The main features of Stainless Steel 630 are:

Corrosion Resistance: Stainless Steel 630 generally provides high corrosion resistance. This makes it attractive for applications exposed to seawater and chemical environments.

High Strength: Stainless Steel 630 can reach high strength levels when heat treated, which makes it suitable for a variety of engineering applications.

Heat Treatment Response: 630 stainless steel responds well to heat treatment such as hardening and tempering, allowing hardness and strength to be adjusted for specific needs.

Aging Resistance: 17-4 PH steel offers resistance to aging, meaning it withstands microstructural changes that can occur over time.

High Temperature Performance: Stainless Steel 630 is resistant to elevated temperatures, making it suitable for industrial furnaces, valves and other high-temperature applications.

Wide Range of Applications: Stainless Steel 630 is used in engineering, aerospace, power generation, the chemical industry, petrochemicals, marine applications and medical devices.

This grade is generally preferred in industrial applications that require durability, corrosion resistance and customizable mechanical properties. Before use, it is important to apply the correct heat treatment according to the requirements of the specific application.
