What is Stainless Steel 430/431 Round bar ?
SS 430 and 431 both are the iron grade steel round bars and rods. They contain up to 98% of alloying elements mutually similar and hence utilized in a wide range of applications. SS 430/4321 round bars are dedicated to perform against deformation at elevated temperature environments. Above round bars, can be operated from low temperature areas up to higher temperature environments. The acceptance of SS 430 and 431 round bars comes from superb resistance to oxidation environments as well as carburizing atmospheres.
The applications of SS 430 and 431 round bars are the furnace components, chemical processing, sparking electrodes, nuclear engineering, and so others. SS 430 grade is an all rounder grade that can be used in any environment, from low temperature environment to elevated temperature up to 2000 Degree F. SS 431 Flat bars can be used to resist stress corrosion cracking from room temperature to high temperature areas. SS 430 and 431 bars also run with good carburizing resistance over a wide range of temperatures. SS 431 rectangular bar has high strength and shows high formability. SS 430 and 431 both have valuable resistance against organic and inorganic compounds.
