Yousef Steel, Riyadh, Saudi Arabia-based, is a reliable manufacturer and supplier of top-grade steel products, serving across different industrial domains. We are expertise in offering Carbon Steel A333 GR 7 Tubing, which is intended for low-temperature and cryogenic service. Our tubing, with attention towards reliability and performance, provides high strength, toughness, and resistance against brittle fracture in harsh conditions. Widely applied in oil, gas, and energy sectors, Yousef Steel guarantees that products are adhering to high standards of the industry, providing long-lasting solutions for essential piping and pressure vessel requirements.
Carbon Steel A333 GR 7 Tubing consists mainly of carbon, manganese, phosphorus, sulfur, and a slight amount of chromium. It commonly has 0.30%–0.60% carbon, 0.90%–1.35% manganese, and others in trace amount, providing fair strength and cryogenic performance. The mechanical attributes are a yield strength of not less than 205 MPa (30 ksi) and a tensile strength of 415–550 MPa (60–80 ksi). This tube provides high toughness and resistance to brittle fracture and is appropriate for application in cryogenic and low-temperature applications, where the tube is retained in structural shape under stress.
