Andre Stainless is one of the leading suppliers and manufacturers of Stainless Steel 17-4 PH Pipes in Pulau Ujong, Singapore. Carefully designed with high performance and put through stringent heat treatment to fulfill precise industrial standards, the pipes are made for uses that demand strength, durability, and corrosion resistance. The pipes, hence, are suitable for hydraulic systems, pressure vessels, and steam lines. Andre Stainless offers various sizes and schedules, both seamless and welded, to meet the special requirements of customers across industries like aerospace, power, oil & gas, and marine infrastructure.
17-4 PH stainless steel consists of approximately 15–17.5% chromium, 3–5% nickel, 3–5% copper, and small amounts of elements such as niobium. It acquires strength by going through a solution treatment followed by aging, which gives tensile strength of up to 1200 MPa and yield strength in the order of 1100 MPa. It has a hardness of up to HRC 40–45, with elongation of 8–10%. Its mechanical properties can be varied by aging at various temperatures (e.g., H900, H1150), and thus it offers design flexibility. Corrosion resistance is usually good in mild to moderate conditions, similar to conventional austenitic stainless steels.
