For over the years, our team at Lathief Pipes in Safat, Kuwait has become a trusted name for industrial materials, and we’re particularly proud to supply high-performance Stainless Steel 348 tubing. We understand that your projects demand reliability, which is why we ensure every length of tube we provide meets the highest standards. When you need durable, heat-resistant tubing that stands up to challenging environments, we’re here to deliver the quality and service you deserve.
This specific stainless steel, known as the “stabilized” grade, contains chromium and nickel like other austenitic steels, but with a key addition of niobium. This composition is what grants it exceptional resistance to intergranular corrosion following exposure to high temperatures. Mechanically, it offers impressive tensile strength and good ductility, allowing it to maintain structural integrity under stress and at elevated temperatures. It’s a material designed for demanding thermal cycling conditions.

Stainless Steel 348 Tubing is applied in heat, corrosion-resistant applications, especially where welding must be done. Typical applications are reactor vessels and heat exchanger tubes, pressure piping, exhaust manifolds, and superheaters in power plants and petrochemical plants. It is also appropriate for nuclear-grade uses because of its stable composition and high stability when exposed to radiation and thermal cycling. Stainless Steel 348 Tubing provides a reliable option for those areas where long-term structural integrity, corrosion resistance, and mechanical strength are essential.
