Lecong Stainless is a reputable manufacturer and supplier based in Da Nang, Vietnam, specializing in high-quality Stainless Steel 17-7 PH Pipes. These pipes are crafted for exceptional strength, corrosion resistance, and durability, making them perfect for critical industrial applications. This particular grade of precipitation-hardening stainless steel boasts impressive mechanical strength, resistance to stress corrosion, and thermal stability, which is why it’s a go-to choice for industries like aerospace, chemical, petrochemical, and marine.
The composition of Stainless Steel 17-7 PH Pipes includes 17% chromium and 7% nickel, along with trace amounts of copper and niobium/tantalum for that extra precipitation hardening. These pipes can achieve tensile strengths between 930 to 1400 MPa, yield strengths of 655–1100 MPa, and elongation rates of 10–20%, depending on how they’re age-hardened. They also show remarkable resistance to stress corrosion cracking, pitting, and oxidation in moderately corrosive environments. This blend of high strength, toughness, and corrosion resistance guarantees reliable performance under high pressure, mechanical stress, and elevated temperatures.
