The ST 35.8 tubing features a carbon steel composition, primarily iron with a controlled amount of carbon, which gives it a great balance of strength and formability. Its key mechanical properties include a minimum yield strength of 235 MPa, ensuring it can handle significant pressure and load without deforming. This tube grade is specifically designed for elevated temperature service, offering excellent resistance to creep, which means it maintains its integrity and shape even under sustained heat and stress, making it a robust choice for demanding environments.
