Among its specialized offerings is the **Low Temperature Carbon Steel A333 Grade 7 pipe**, engineered specifically for sub-zero and cryogenic applications. Manufactured in accordance with ASTM A333 standards, this grade is perfect for sectors like LNG, oil and gas, petrochemicals, and offshore operations where low-temperature toughness and structural integrity are crucial. Yousef Steel ensures product reliability, offers technical support, and guarantees timely delivery to meet the needs of its clients.
ASTM A333 Grade 7 is a low-temperature carbon-manganese steel that incorporates nickel to boost notch toughness and performance in low temperatures. Its typical chemical makeup features carbon (max 0.19%), manganese (0.90–1.60%), phosphorus (max 0.025%), sulfur (max 0.025%), and nickel (0.40–1.06%). The mechanical properties include a minimum yield strength of 240 MPa and a minimum tensile strength of 450 MPa. Designed to operate in temperatures as low as -100°F (-73°C), Grade 7 undergoes mandatory impact testing to confirm its suitability for cryogenic and arctic service conditions. It also boasts good weldability and formability.
