Stainless Steel 17-4PH Coils, also known as UNS S17400, are heat-treatable stainless steel coils that offer a unique combination of corrosion resistance and high strength. These coils provide a versatile solution for industries such as aerospace, petrochemicals, marine, automotive, and food processing. Due to their outstanding strength-to-weight ratio and ability to withstand corrosive environments, these coils are among the most preferred grades for precision-engineered parts. The precipitation-hardening feature allows for various strength levels, depending on heat treatment (e.g., H900, H1025, H1150). Our coils meet both ASTM A693 and ASME SA693 standards, ensuring compliance with international quality benchmarks.

One of the key advantages of Stainless Steel 17-4PH Coils lies in their outstanding mechanical properties. These include high tensile strength, excellent wear resistance, and reliable hardness even in elevated temperatures up to 600°F (316°C). The material’s corrosion resistance rivals that of austenitic grades, making it suitable for challenging environments, especially where chloride stress corrosion is a concern. The alloy’s machinability and weldability are also strong selling points, with good toughness and dimensional stability during fabrication. At SMM Industries LLP, our role as one of the top Stainless Steel 17-4PH Coils Suppliers ensures we deliver coils that align with your exact performance needs and international material specifications.

The applications of Stainless Steel 17-4PH Coils span across multiple industries due to their impressive mechanical properties and corrosion resistance.

• Aerospace Components – Used in aircraft frames, turbine blades, and structural components due to its strength-to-weight ratio and resistance to fatigue.

• Oil and Gas Industry – Ideal for offshore platforms and pressure-containing equipment that demand corrosion and stress resistance.

• Marine Applications – Perfect for shipbuilding and components exposed to seawater thanks to its rust resistance and mechanical endurance.

• Food Processing Equipment – Non-reactive nature and high cleanliness make it suitable for equipment in hygienic environments.

• Medical Devices – Used in surgical instruments and orthopedic implants because of its biocompatibility and strength.

• Power Generation – Used in nuclear and thermal plants for parts exposed to high heat and pressure cycles.

• Pulp and Paper Industry – Withstands chemical exposure and abrasive processing conditions.

• Automotive Industry – Applied in exhaust systems, engine components, and suspension parts where high performance is crucial.

• Defense Equipment – Utilized in armored vehicles and ballistic hardware for impact resistance.

• Injection Molds – Preferred in tooling applications due to its hardness and wear resistance.

Globally, Stainless Steel 17-4PH Coils are referred to by various names under different national standards. In the United States, they are identified as ASTM A693 Grade 630 and ASME SA693.
