Renowned for timely delivery, consistent quality, and customer-focused service, the company has become a trusted provider of stainless steel tubing for industries across Oman and neighboring regions.
Stainless Steel 310S Tubing is an austenitic stainless steel alloy containing chromium (24–26%) and nickel (19–22%) with low carbon content to enhance corrosion resistance and prevent carbide precipitation. This composition ensures excellent high-temperature performance, scaling resistance, and thermal fatigue stability. Mechanically, 310S tubing provides tensile strength of 515–690 MPa, yield strength of 205–310 MPa, and good toughness and ductility. The material also offers reliable weldability, formability, and dimensional stability under thermal cycling, making it suitable for high-temperature and industrial applications where strength and durability are critical.
