Nestled in the heart of Kinshasa, Sadiki Metals has built a reputation as a trusted partner for industrial and construction needs across Congo. We take pride in manufacturing and supplying robust, reliable fastening solutions, with our Stainless Steel 330 Stud Bolts standing as a prime example of our commitment to quality. These bolts are engineered to meet the demanding challenges of modern projects, offering a perfect blend of strength and exceptional resistance to high temperatures, ensuring your structures and equipment are secured with confidence for the long term.
The strength of these stud bolts comes from their specific makeup. They are crafted from an austenitic stainless steel known as 330, which contains a careful balance of chromium and nickel. This particular composition gives the material outstanding mechanical properties, including high tensile strength and excellent ductility. Most importantly, it retains this strength even under intense heat, resisting oxidation and scaling up to about 1100°C, which makes it far superior to many other alloys in high-temperature environments.
