Yousef Steel stands out as a top manufacturer and supplier in Riyadh, Saudi Arabia, specializing in high-quality Carbon Steel A333 GR 7 Tubing. These tubes are expertly crafted for low-temperature and high-pressure applications, ensuring exceptional toughness, durability, and reliability. Built to meet ASTM A333 standards, Carbon Steel A333 GR 7 Tubing is a go-to choice in the oil and gas, petrochemical, and industrial process sectors. Yousef Steel guarantees precise dimensions, a smooth surface finish, and consistent mechanical performance, providing tubing solutions that rise to the challenges of today’s industrial and energy needs.
The composition of Carbon Steel A333 GR 7 Tubing primarily includes carbon and iron, along with carefully controlled amounts of manganese, phosphorus, sulfur, and other alloying elements that boost low-temperature toughness and mechanical strength. This tubing showcases impressive tensile and yield strength, good elongation, and outstanding resistance to fractures and deformation in cold conditions. Plus, it offers excellent weldability, machinability, and structural integrity, making it perfect for low-temperature and high-pressure environments.Carbon Steel A105 Forged Fittings consist mainly of carbon, along with traces of manganese, phosphorus, sulfur, and silicon. The usual composition is 0.35% carbon, 0.60-0.90% manganese, and traces of other elements. These fittings have very good mechanical properties, such as tensile strength of 485-620 MPa, yield strength of 250 MPa, and elongation of 20-25%. The material is extremely tough, corrosion-resistant, and able to withstand high pressures and temperatures and is thus suited for extreme use in the oil, gas, and petrochemical sectors.
