Nakamura Stainless, based in Pulau Ujong, Singapore, stands out as a top manufacturer and supplier of high-performance stainless steel products tailored for tough industrial and commercial needs. One of their standout products, the Stainless Steel 17-7 PH Fasteners, is highly regarded for its remarkable strength, resistance to corrosion, and unique precipitation-hardening features. These fasteners are meticulously designed to perform exceptionally well in high-stress, fatigue-prone, and corrosive environments. With cutting-edge manufacturing processes, rigorous quality checks, and timely delivery, Nakamura Stainless caters to various sectors, including aerospace, automotive, marine, and chemical processing, offering dependable fastening solutions throughout Singapore and beyond for precision and high-strength applications.
Stainless Steel 17-7 PH Fasteners are primarily made up of chromium (16–18%), nickel (6.5–7.75%), and aluminum (0.75–1.5%), which provide them with excellent corrosion resistance and precipitation-hardening abilities. After undergoing the right heat treatment, they can reach impressive tensile strengths of up to 1100 MPa, along with exceptional hardness, fatigue resistance, and dimensional stability. These fasteners also maintain good ductility in their annealed state, making them easier to work with before hardening. Their well-balanced alloy composition guarantees reliable performance under cyclic loads and in mildly aggressive environments, making them perfect for demanding, high-strength fastening tasks across various industries.
