Rupal Metals stands out as a leading manufacturer and supplier of Stainless Steel 446 Hex Bars in Delhi, India. They provide top-notch, corrosion-resistant solutions designed for high-temperature and oxidizing environments. Stainless Steel 446 is a ferritic, non-heat-treatable stainless steel that boasts remarkable resistance to oxidation, sulfidation, and various forms of corrosion, even at elevated temperatures. Rupal Metals offers hex bars in a range of sizes and specifications, customized to meet the specific needs of clients across industries like heat treatment, chemical processing, and power generation. These hex bars are perfect for applications that demand strength, thermal stability, and a long service life in tough conditions.
Stainless Steel 446 Hex Bars mainly consist of Chromium (23–27%), with Iron making up the balance, along with trace amounts of Manganese, Silicon, Carbon, and Molybdenum. The high chromium content grants outstanding resistance to oxidation and scaling at temperatures reaching up to 1100°C. SS 446 has a tensile strength of about 485 MPa, a yield strength of 275 MPa, and an elongation of roughly 20%. While it may have lower ductility and toughness compared to austenitic grades, it excels in corrosion resistance in extreme heat and chemical environments. Its ferritic structure ensures magnetic properties and resistance to chloride stress corrosion cracking.

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.
Stainless Steel 446 Hex Bars find extensive use in high-temperature industrial settings where oxidation and sulfidation resistance are crucial. They are commonly used in furnace parts, heat exchanger tubes, burners, boiler baffles, and muffles. In the chemical and petrochemical sectors, SS 446 is ideal for components that face aggressive chemicals and extreme thermal cycling. It’s also well-suited for kiln linings, incinerator parts, and exhaust systems. Thanks to its corrosion resistance and thermal stability, it’s a go-to material for heat treatment trays and baskets, ensuring durability and reliability over the long haul.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
