Known for their unwavering commitment to quality, the company prioritizes precision in their manufacturing processes, ensuring durability and adherence to international standards. With a strong focus on customer satisfaction, Sadiki Metals delivers dependable products that cater to a wide range of industrial needs. Their Stainless Steel 304H bars and rods are produced using cutting-edge metallurgical techniques, providing outstanding strength, resistance to corrosion, and excellent performance even in high-temperature environments. This makes them a go-to choice for demanding applications in construction, engineering, and manufacturing.
The composition of Stainless Steel 304H bars and rods includes iron, 18–20% chromium, 8–10% nickel, along with small amounts of carbon, manganese, and silicon. The higher carbon content compared to 304L boosts strength at elevated temperatures while still offering corrosion resistance. In terms of mechanical properties, they boast a tensile strength of about 515–750 MPa, a yield strength of around 205–310 MPa, and an elongation of 40–50%, which ensures excellent formability and weldability. Their stability at high temperatures, along with resistance to oxidation and thermal fatigue, makes them ideal for heavy-duty industrial applications where both mechanical performance and durability are essential.
