Pengkumta Fasteners, a top-notch manufacturer and supplier based in Bangkok, Thailand, is dedicated to providing high-quality Stainless Steel 304L Stud Bolts designed for a variety of industrial applications. These stud bolts are celebrated for their resistance to corrosion, impressive durability, and outstanding weldability, making them perfect for essential fastening needs. Produced under strict quality controls, they guarantee consistent performance and reliability across different environments. With a solid reputation for precision engineering and prompt delivery, Pengkumta Fasteners has established itself as a trusted partner for Stainless Steel 304L Stud Bolts in both local and global markets.
Stainless Steel 304L Stud Bolts are made up of iron, 18–20% chromium, 8–12% nickel, and have a lower carbon content compared to the standard 304 grade. This reduced carbon helps minimize carbide precipitation during welding, which boosts both corrosion resistance and weldability. These stud bolts boast a tensile strength of around 485 MPa and a yield strength of about 170 MPa. With excellent toughness, resistance to oxidation, and mechanical stability, Stainless Steel 304L Stud Bolts perform reliably in both cryogenic conditions and moderately high-temperature settings.
