17‐4 PH pipes (sometimes called S17400, a universal designation also) constitute a high strength and corrosion-resisting stainless steel alloy in which good mechanical properties are required as well as good oxidation resistance. These pipes have been manufactured to the ASTM A564 specifications and would be ideal in most industrial applications such as petrochemical, aerospace, marine, food processing and general engineering applications. With a stamp of unrivalled quality and precision, Hindco Steel And Alloys is one of the leading manufacturers and suppliers of high-standard 17-4 PH Pipes specifying global needs with absolute perfection and flawlessness.
The 17-4 PH is chiefly composed of chromium, nickel, copper which makes the alloy exceptionally strong and hard upon heat treatment, and thereby making it in great demand in structural applications and pressure systems. This stainless steel is a precipitation hardened type, which offers great tensile strength and yield strength and hence is a very good substitute to carbon steels in addition to having significantly high corrosion resistance and resistance to stress cracking. Incorporation of 3-5 copper and variable level of niobium improves hardenability and strength of the pipes and provides stable mechanical characteristics under hard service conditions.
The addition of rare earth metals to 253 MA leads to increased durability of oxide layer that renders long service life of the metals to perform in the environment that is subjected to thermal cycling. This renders the pipes applicable as in heat exchangers, power plant, petrochemical, furnaces, boilers and the other process systems operating at high temperatures.
Hindco Steel And Alloys takes pride in the idea that every one of the 17-4 PH Pipes produced by our company is put through strict evaluation levels and dimensional precision. We carry many sizes and thicknesses of wall panels with customization provided on-demand depending on the requirements of the client. We have the latest machinery in our infrastructure and this allows us to provide quick turnaround with no adjustment in quality. We also give third party inspection and certification and that is all transparent and clients are satisfied.
