Khaled Stainless, located in Cairo, Egypt, specializes in providing Stainless Steel 330 stud bolts that are specifically designed for high-temperature and oxidation-resistant fastening applications. These bolts are crafted from certified SS 330 bar stock, featuring precise threading, controlled tolerances, and consistent mechanical integrity. They’re built to withstand the rigors of extreme thermal environments. Khaled Stainless supplies these 330 stud bolts to furnace builders, petrochemical plants, heat-treating equipment manufacturers, and industries that deal with high temperatures where standard stainless fasteners often fail. With complete material traceability, thorough quality inspections, and reliable delivery schedules, Khaled Stainless guarantees secure, long-lasting bolted joints even in the toughest thermal and oxidative conditions.
Stainless Steel 330 is a high-nickel, high-chromium austenitic alloy that contains about 33–37% nickel and 17–20% chromium, along with controlled amounts of carbon and silicon to enhance its resistance to oxidation and carburization at elevated temperatures. Its typical mechanical properties include a tensile strength of around 550–750 MPa, yield strength ranging from 205–310 MPa, and an elongation of 30–45%, depending on the condition. SS 330 maintains its structural stability, creep resistance, and toughness at temperatures above 1000°C, making it ideal for long-term thermal service and environments that experience repeated heating and cooling.

We have a high-quality assurance of the complete transparency of our Stainless Steel 330 Stud Bolts. The orders come along with some documents, like a commercial invoice, a packing list, a fumigation certificate, a heat treatment chart, and a NABL-approved lab test report. Material Test Certificates per EN 10204/3.1b, PMI Test Certificates, 100% radiography test reports, and Third-Party Inspection Certificates are provided by us. We arrange all of our documentation completely for maximum client satisfaction.
SS 330 stud bolts are essential for bolted joints that face extreme heat, oxidation, thermal cycling, and carburizing atmospheres. They are commonly used in furnace assemblies, radiant tube supports, petrochemical heater coils, reformer units, burners, heat-treating equipment, kiln structures, high-temperature piping, and incinerators. These stud bolts are preferred in situations where other grades like 310, 316, or 304 tend to lose their mechanical properties.
