Uday Flanges is a well-established Stainless Steel 17-4 PH flanges manufacturer and supplier with pride located in Dubai, UAE. Uday Flanges specializes in providing high-strength corrosion-resistance flange solutions to industries requiring precision, durability, and reliability under harsh conditions. Stainless Steel 17-4 PH is a precipitation-hardening martensitic stainless steel, which best suits applications where a combination of mechanical strength and moderate corrosion resistance is needed. These flanges find extensive application in aerospace, chemical processing, marine, and power generation industries. Uday Flanges is dedicated to quality, performance, and timely delivery for all customers.
Stainless Steel 17-4 PH flanges consist mainly of 15–17.5% chromium, 3–5% nickel, 3–5% copper, and traces of niobium (columbium). The material obtains its high strength due to heat treatment as well as precipitation hardening. These flanges have remarkable mechanical properties, such as tensile strength of up to 1100 MPa and yield strength of up to 1000 MPa, depending on the heat treatment condition (most commonly H900 to H1150). 17-4 PH has good corrosion resistance, similar to 304 stainless steel, as well as excellent wear resistance, toughness, and dimensional stability in a broad range of operating conditions.

Stainless Steel 17-4 PH flanges are employed in demanding applications where high strength, superb fatigue resistance, and assured corrosion protection are needed. Representative applications include turbine parts, high-pressure piping, nuclear waste processing equipment, valve components, offshore platforms, and aerospace structural assemblies. These flanges are particularly valuable in applications that involve heavy mechanical loads and corrosive media. Their hardenability by heat treatment and their performance in oxidizing and mild chloride environments make them an engineers’ first choice for designing equipment for tough or safety-critical service.
