Aung Metals, a leading manufacturer and supplier located in Naypyidaw, Myanmar, specializes in top-notch **Stainless Steel 446 Hex Bars**. These bars are celebrated for their remarkable corrosion resistance, impressive strength at high temperatures, and overall durability. Crafted with precision and in line with international standards, they deliver exceptional performance even in the toughest industrial settings. Thanks to their high chromium and low carbon makeup, 446 stainless steel stands out with its excellent resistance to oxidation, scaling, and pitting, ensuring they remain reliable over time. Aung Metals’ 446 Hex Bars find their place in various sectors, including chemical processing, power generation, marine applications, and high-temperature environments, where they provide both structural integrity and operational efficiency under extreme conditions.
These Stainless Steel 446 Hex Bars are primarily made up of 23–27% chromium, with a carbon content of ≤0.2%, along with trace amounts of manganese, silicon, and molybdenum. This unique composition gives them outstanding resistance to corrosion and oxidation, especially at elevated temperatures. They boast a tensile strength ranging from 450–650 MPa, a yield strength of 200–300 MPa, and an elongation of 20–30%, all while maintaining good hardness and toughness. Their ability to withstand high temperatures and their mechanical strength make them perfect for applications that demand long-lasting durability in challenging environments.

SS 446 Hex Bars offer excellent corrosion resistance, high strength, and durability, making them ideal for harsh industrial environments. Their resistance to oxidation and high-temperature stability ensure reliability in applications like heat exchangers, chemical processing, and petrochemical industries.
SS 446 Hex Bar has superior high-temperature strength and excellent resistance to oxidation compared to other stainless steel alloys like SS 304 or SS 316. Its enhanced durability and corrosion resistance make it ideal for high-stress environments, such as heat exchangers, where other alloys may degrade or weaken over time.
Common machining techniques for SS 446 Hex Bars include turning, milling, drilling, and grinding. Challenges include its high hardness and tendency to work-harden, which can lead to tool wear. Proper lubrication and slower cutting speeds are necessary to maintain tool life and achieve smooth, accurate finishes.
Aung Metals’ Stainless Steel 446 Hex Bars are extensively used in industries where heat and corrosion resistance are paramount. They are perfect for components in furnaces, heat exchangers, chimneys, gas burners, and high-temperature structural parts. Moreover, they play a crucial role in chemical processing equipment, marine applications, and boiler systems that face corrosive and high-temperature conditions. With their blend of mechanical strength, corrosion resistance, and dimensional stability, these hex bars ensure reliable performance, a long service life, and efficiency in demanding industrial and engineering applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
