Anucha Metals, a top-notch manufacturer and supplier based in Bangkok, Thailand, specializes in high-quality Stainless Steel 316H Bars and Rods designed for tough, high-temperature, and corrosive settings. These bars and rods are well-known for their outstanding resistance to pitting, crevice corrosion, and oxidation, especially in chemical and chloride-heavy environments. With a higher carbon content than 316L, Stainless Steel 316H offers enhanced strength at elevated temperatures while still being resistant to corrosion and easy to weld. Anucha Metals prides itself on delivering precision-engineered products that adhere to international standards, catering to various industries like chemical processing, marine, oil & gas, power generation, and pharmaceuticals, all while providing durable, reliable, and high-performance stainless steel solutions.
The composition of Stainless Steel 316H Bars and Rods includes 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and a higher carbon content compared to 316L, along with small amounts of manganese and silicon. This blend results in improved mechanical strength at high temperatures while ensuring excellent corrosion resistance. In terms of mechanical properties, they boast a tensile strength of 515–690 MPa, yield strength of 205–310 MPa, and an elongation of up to 40%. The alloy is known for its high-temperature toughness, creep resistance, and dimensional stability, making it perfect for critical industrial applications that face thermal and stress-intensive conditions.
