ASTM A333 Grade 4 is a low-alloy steel pipe containing nickel as the main alloying element, as well as manganese, phosphorus, sulfur, silicon and other elements. It has excellent mechanical properties and corrosion resistance in low temperature environments.
A333 Grade 4 alloy steel pipe has specified mechanical properties including a minimum yield strength of 240 MPa (35,000 psi) and a minimum tensile strength of 415 MPa (60,000 psi).
The ASTM A333 low-temperature steel pipes provided by GNEE have also undergone Charpy V-notch impact testing to ensure the material's ability to absorb energy at low temperatures. This testing is a key requirement for steel pipes to ensure their reliability and safety in practical applications.
ASTM A333 Grade 4 cryogenic steel pipe is commonly used to withstand cryogenic temperatures as low as -50°C (-75°F).
Common applications for ASTM A333 Grade 4 steel pipe include cryogenic storage tanks, cryogenic process systems and piping operating in cryogenic environments. These applications cover the manufacturing and transportation of a wide range of cryogenic equipment and systems in areas such as petroleum, chemicals and natural gas.
