Midland, UK-based Weston Stainless is a reliable manufacturer of stainless steel products that offer long-lasting and precision-made solutions for numerous industrial uses. Its Stainless Steel 330 Nuts are made of a heat-resistant austenitic stainless steel alloy that has outstanding oxidation and carburization resistance at high temperatures. The nuts come in hex, heavy hex, square, coupling, and wing nut shapes and provide reliable and long-term connections under severe conditions. With better mechanical strength, corrosion resistance, and thermal stability, SS 330 nuts are perfect for use in applications demanding toughness in high-temperature and chemically corrosive environments.
Stainless Steel 330 Nuts have 34-37% nickel, 17-20% chromium, and 1.0-1.5% silicon content, which provides them with increased oxidation and carburization resistance at elevated temperatures. The nuts possess a tensile strength of around 550 MPa, a yield strength of 230 MPa, and an elongation of 30%. Their hardness is approximately 95 HRB. Physical properties are a density of 7.9 g/cm³, a melting point of 1400-1425°C, and a thermal conductivity of 12.1 W/m-K, which makes them ideal for extreme heat and stress conditions in industrial processes.

We are committed to providing our clients with the finest quality Stainless Steel 330 Nuts. To ensure their outstanding quality, our nuts undergo a thorough series of testing processes before they are dispatched. These tests include hardness testing, chemical analysis via spectro analysis, positive material identification (PMI) testing, flattening tests, micro and macro examinations, pitting resistance tests, flaring tests, and intergranular corrosion (IGC) tests. We also provide third-party inspection certificates to give our clients extra confidence in the quality and suitability of our Stainless Steel 330 Nuts for various applications.
Weston Stainless offers test certificates, such as Mill Test Certificates (MTC) according to EN 10204 3.1, to meet international quality standards. The nuts are safely packed in wooden crates, bubble wrap, or carton boxes to avoid damage during transportation. With an effective logistics system, Weston Stainless ensures prompt and reliable global delivery, serving urgent industrial needs with precision and care.
