Khaleed Stainless, Riyadh, Saudi Arabia, is a renowned manufacturer and supplier of stainless steel fasteners of high quality, catering to various industrial segments. Among its value-added products are Stainless Steel 347 Stud Bolts intended to perform superbly at high temperatures and corrosive conditions. These stud bolts are stabilized by niobium (columbium), conferring enhanced resistance to intergranular corrosion and stress cracking when welding and cycling thermally. Khaleed Stainless is reputable for precision, reliability, and dedication to quality, serving industries in Saudi Arabia and the Middle East.
Stainless Steel 347 Stud Bolts consist of 17–19% chromium, 9–13% nickel, with niobium stabilization to avoid carbide precipitation when being exposed to high temperatures. The stud bolts have superior oxidation resistance and sustain strength under high thermal conditions. They provide a tensile strength of around 75 ksi, a yield strength of about 30 ksi, and elongation of around 40%. Their chemical makeup and mechanical steadiness qualify them for extended high-temperature use, particularly where welding is involved.
