ST 35 and ST 35.8 are low carbon steel grades that are commonly used in seamless tubing applications. Their typical chemical makeup includes up to 0.17% Carbon, 0.40% Manganese, along with trace amounts of Silicon, Phosphorus, and Sulfur. These materials are known for their good weldability and machinability. ST 35 tubing has a tensile strength ranging from 440 to 570 MPa and a yield strength of about 235 MPa. On the other hand, ST 35.8, which is designed for higher temperatures, offers slightly enhanced strength and thermal stability. Both grades excel in pressure resistance, making them perfect for structural and high-temperature tubing applications in boiler and heat exchanger systems.
