17-4 PH Stainless Steel is one of the most widely used precipitation hardening alloys in industrial applications where high strength, excellent corrosion resistance, and durability under extreme conditions are required. In Kuwait, industries such as oil & gas, petrochemical processing, marine engineering, power generation, and construction rely heavily on high-performance metals that can withstand harsh climates, saltwater exposure, and high pressure conditions.
As a leading 17-4 PH Round Bar Manufacturer in Kuwait, we provide premium quality UNS S17400 / Grade 630 stainless steel round bars that are engineered to deliver long-lasting performance and reliability. Our products are manufactured according to international standards and are supplied in a wide range of sizes, heat treatment conditions, finishes, and lengths, ensuring they meet diverse project and machinery requirements.
What is 17-4 PH Stainless Steel Round Bar?
17-4 PH (also known as Grade 630) is a martensitic precipitation hardening stainless steel that is strengthened through a heat treatment process known as precipitation hardening. Unlike conventional stainless steels, 17-4 PH can be hardened to different strength and hardness levels by applying controlled heat treatments such as H900, H1025, H1075, and H1150.
This alloy is favored for its high mechanical strength, excellent corrosion resistance, and good performance in high-temperature environments. These properties make it particularly suitable for critical and corrosive applications commonly found in Kuwait’s industrial sectors.
Chemical Composition of 17-4 PH Round Bar (UNS S17400)
| Element | Percentage (%) |
|---|---|
| Chromium (Cr) | 15.5 – 17.5 |
| Nickel (Ni) | 3.0 – 5.0 |
| Copper (Cu) | 3.0 – 5.0 |
| Manganese (Mn) | ≤ 1.0 |
| Silicon (Si) | ≤ 1.0 |
| Carbon (C) | ≤ 0.07 |
| Iron (Fe) | Balance |
The combination of chromium and copper in the alloy enhances corrosion resistance and hardenability, allowing the material to maintain strength and structural integrity even in demanding environments.
Mechanical Properties of 17-4 PH Round Bar
The mechanical properties vary depending on the heat treatment condition:
| Condition | Tensile Strength (MPa) | Yield Strength (MPa) | Hardness (HB) |
|---|---|---|---|
| H900 | ~1310 | ~1170 | 375 |
| H1025 | ~1170 | ~1035 | 331 |
| H1150 | ~1040 | ~965 | 302 |
These properties make it ideal for pressure systems, load-bearing components, high-stress machinery parts, and corrosive-environment applications.
