S45000 (Custom 450) stainless steel is a highly alloyed austenitic stainless steel designed for harsh and highly corrosive environments, such as those encountered in chemical processing equipment, power generation and industrial pumps. It provides superior corrosion resistance, superior strength and superior abrasion resistance over types 304, 316 and S31700 stainless steels.
Custom 450 is a precipitation hardening stainless steel enhanced by the addition of additional alloying elements and by cold working to increase its strength. It is available in many grades, such as S45000, with differing levels of strength and corrosion resistance. The higher grades are often used for critical components in power generation, chemical processing and other highly hostile environments.
Custom 450 offers high strength, good formability, excellent resistance to pitting, crevice corrosion and stress corrosion cracking, and it is also heat treatable. It has excellent abrasion resistance and is sometimes used in applications such as pumps, valves, and fittings. Custom 450 stainless steel can also be used in marine environments and is a good choice for food processing, petrochemical and papermaking equipment.
Custom 450 is a high-alloy, austenitic stainless steel containing chromium, nickel and molybdenum as alloying elements. It also contains copper, niobium and nitrogen. These additions increase the strength and formability of the material and also enhance its resistance to corrosion and abrasion. The alloy is heat treatable and when specifically formulated, providing higher strength at higher temperatures.
Custom 450 alloy is typically used in high-temperature, high-pressure industrial applications such as chemical processing, power generation and industrial pumps, due to its superior corrosion resistance and high strength. Its excellent formability also makes it suitable for uses in stainless steel tanks, pipes and other equipment. Its excellent weldability and good temperatures characterize it for uses in many industrial processes, such as provide added strength and corrosion resistance.
Custom 450 stainless steel provides superior performance under challenging environments. It offers excellent performance in the most hostile environments owing to the combination of its strength, formability and corrosion resistance properties. It is also heat treatable, enabling it to be used in many applications. Custom 450 is a viable option for many industries, as its corrosion resistance properties can reduce maintenance costs and replacement over time significantly.
