Horizon Metal & Alloys manufactures SS 17-4 PH fasteners engineered for applications where both strength and corrosion resistance are critical. As a specialized 17-4 PH fasteners manufacturer in India, we supply components that maintain structural integrity under high stress, fluctuating temperatures, and corrosive environments.
17-4 PH is a precipitation-hardening martensitic stainless steel that combines chromium, nickel, and copper to achieve a unique balance of hardness and toughness. Controlled heat treatment allows the material to reach specific strength levels, making it suitable for applications that require predictable mechanical performance. Compared to standard stainless grades, stainless steel 17-4 PH fasteners offer higher tensile strength without sacrificing resistance to oxidation or moisture exposure.
Our range includes 17-4 PH bolts, stud bolts, threaded rods, and precision-machined components designed for load-bearing assemblies. These fasteners are commonly used in sectors such as marine equipment, petrochemical processing, power generation, and heavy fabrication, where failure is not an option.
Each SS 17-4-Ph Fasteners have unique design each of them are used in specific applications. Some of them are mentioned below.
Product range
We supply a complete range of SS 17-4 PH fasteners, including hex bolts, socket head cap screws, stud bolts, anchor bolts, U-bolts, nuts, washers, and threaded rods. Custom dimensions and machining options are available for project-specific requirements.
Note that this chart includes only some of the most common sizes of SS 17-4-Ph Bolt. There are many other sizes available as well, and some applications may require custom sizes or special configurations.
| SS 17-4-PH Fasteners | Element (% by Mass) |

The key advantage of 17-4 PH stainless steel fasteners lies in their ability to deliver high strength with consistent dimensional stability. Their resistance to corrosion in freshwater and mildly saline environments makes them suitable for offshore structures, valves, pumps, and pressure systems. Because strength can be tuned through heat treatment, these fasteners are often selected for precision assemblies where both load capacity and reliability are essential.
As a Mumbai-based supplier, we provide 17-4 PH fasteners in India with consistent quality, traceable materials, and reliable delivery schedules. Orders can be fulfilled in bulk or custom specifications depending on project requirements.
We specialize in manufacturing high-quality fasteners that cater to diverse industries, including oil & gas, petrochemical, marine, power generation, aerospace, and construction.
