With a solid foothold in Dubai, UAE, Andre Stainless focuses on crafting Stainless Steel 321H Flanges, which are celebrated for their exceptional strength and durability. The company strictly follows international quality standards and offers tailored solutions to cater to various industrial requirements. By utilizing cutting-edge manufacturing techniques and a talented workforce, Andre Stainless guarantees timely deliveries and unmatched product reliability, making it the go-to choice for clients in search of Stainless Steel 321H Flanges in the UAE and beyond.
Stainless Steel 321H Flanges are made from titanium-stabilized austenitic stainless steel, featuring a higher carbon content that boosts high-temperature strength. This alloy typically contains chromium (17-19%), nickel (9-12%), and titanium (at least five times the carbon content), along with trace elements like manganese, silicon, and phosphorus. These flanges boast impressive mechanical properties, including a tensile strength of 515 MPa, yield strength of 205 MPa, and an elongation of 35%. They perform reliably in environments that demand resistance to oxidation and intergranular corrosion, especially at temperatures reaching up to 900°C, making them perfect for high-heat service conditions.
