We offer These Stainless Steel 446 Forgings as per DIN, ISO, JIS or ANSI Standard.
High Temperature Resistance: Stainless steel 446 can withstand high temperatures up to 1100-1150°C (2010-2100°F) in continuous service. This makes it suitable for forging applications where exposure to elevated temperatures is common.
Oxidation Resistance: It has excellent oxidation resistance, even in cyclic conditions, which is crucial for applications where the metal is exposed to air at high temperatures.
Corrosion Resistance: Stainless steel 446 exhibits good resistance to corrosion, particularly in environments with high chloride content. This makes it suitable for forging components used in mildly corrosive environments.
Creep Resistance: It has good creep strength at elevated temperatures, allowing it to maintain mechanical properties under prolonged exposure to heat and load.
Ease of Fabrication: Stainless steel 446 is relatively easy to forge, weld, and machine compared to some other high-temperature alloys, which facilitates manufacturing processes.
Stainless Steel 446 Forgings applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
High-Temperature Furnace Components: Stainless steel 446 is often used in the manufacture of components for high-temperature furnaces and equipment where temperatures can reach up to 1100-1150°C (2010-2100°F). This includes radiant tubes, muffles, retorts, and conveyor belts.
Thermal Processing Equipment: It is utilized in thermal processing equipment such as kilns, annealing covers, and combustion chambers where resistance to oxidation and thermal cycling is crucial.
Chemical Processing: Components like reactors, heat exchangers, and boiler baffles in chemical processing plants benefit from stainless steel 446’s resistance to corrosion from acids, alkalis, and sulfurous atmospheres.
Temperature Requirements: Determine the maximum operating temperature of your application. Stainless steel 446 is suitable for continuous service up to around 1100-1150°C (2010-2100°F). Ensure the forgings can withstand the temperatures they will be exposed to without compromising their mechanical properties.
Corrosion Resistance: Evaluate the environment where the forgings will be used. Stainless steel 446 offers good resistance to oxidation and corrosion in mildly corrosive environments, but it may not be suitable for highly acidic or chloride-rich environments compared to austenitic stainless steels. Ensure it matches the specific corrosion resistance requirements of your application.
Mechanical Properties: Consider the mechanical properties required for your application, such as tensile strength, yield strength, and hardness. Stainless steel 446 offers good creep strength and resistance to thermal cycling, but ensure the forgings meet the mechanical load and stress requirements of your equipment.
Stainless steel 446 forgings are generally resistant to galvanic corrosion due to their high chromium content, which forms a protective oxide layer. However, in specific environments with dissimilar metals and electrolytes, galvanic corrosion can occur, necessitating careful consideration of the application conditions to prevent potential issues
When selecting stainless steel 446 forgings, consider their high-temperature resistance (up to 1100-1150°C), oxidation resistance, corrosion resistance in moderate environments, mechanical properties suitable for high-stress applications, ease of fabrication, and compliance with industry standards. Evaluate application-specific needs to ensure optimal performance and longevity.
Yes, stainless steel 446 forgings are recyclable. Like other stainless steels, they can be recycled through standard scrap metal recycling processes. Recycling stainless steel helps conserve natural resources, reduces energy consumption, and minimizes waste in manufacturing, making it an environmentally sustainable choice.
Stainless steel 446 forgings generally do not require corrosion protection coatings due to their inherent resistance to oxidation and moderate corrosion in many environments. However, in aggressive or highly corrosive conditions, appropriate coatings or surface treatments may be considered to enhance longevity and performance.
