Sahil Metals stands out as a leading manufacturer and supplier of Alloy 20 Round Bars in Riyadh, Saudi Arabia. They specialize in high-performance nickel–iron–chromium alloy solutions that are crafted for exceptional corrosion resistance. Known as Carpenter 20, Alloy 20 is particularly prized in chemical and industrial settings due to its remarkable resistance to sulfuric acid and other harsh substances. Sahil Metals is committed to precision engineering, upholding strict quality standards, and tailoring specifications to fit a variety of customer needs. With its durability, strength, and long-lasting performance, Alloy 20 round bars find extensive use in the petrochemical, pharmaceutical, food processing, and marine industries for critical applications.
Alloy 20 Round Bars are made up of roughly 32–38% nickel, 19–21% chromium, 3–4% copper, 2–3% molybdenum, ≤1% manganese, ≤1% silicon, ≤0.07% carbon, along with small amounts of niobium and iron to balance the composition. This unique blend provides outstanding resistance to stress corrosion cracking, pitting, and acid attack. On the mechanical side, Alloy 20 boasts a tensile strength of about 620 MPa, a yield strength of around 300 MPa, elongation rates of 30–35%, and a Brinell hardness close to 217 HB. Its combination of toughness, ductility, and corrosion resistance makes it ideal for demanding industrial environments.
