AISI 440C Stainless Steel Round Bar details-
The bars are designed for application in high temperature corrosive environments. These bars offer good service in oxidizing environments under dense cyclic environments. These bars are highly resistive to sulfidation and moderate corrosion in severe carburizing conditions. They are ideally used in thermal process streams. SS round bars are utilized in slightly oxidizing, fluctuating heating, nitrating, and cementing applications.
These bars are used in cryogenic temperatures with down magnetic properties and to lower toughness. AISI 440C Stainless Steel is heated to subject sigma phase precipitation. Moreover, it is solution annealed to attain a high degree of toughness.
AISI 440C Stainless Steel is easy to fabricate and it can be easily modified into any complex designs without any further higher costs. It is easily modified by standard machines associated with the grade. This grade is modified for improved creep resistance. The grain size and alloying elements can attain requirements for strength and resistance property. These are readily weldable with standard shop fabrication operations. All standard welding operations can be used for welding.
AISI 440C Stainless Steel Round Bars offer good service in the wet corrosive environments. This grade has a detrimental phase on the wet corrosion environments. However, this alloy is prone to intergranular corrosion environments even in higher temperatures. The bars are highly resistive to pitting and crevice corrosive environments. It also serves good performance in the chemical processing environments such as nitric acids, phosphoric acids, acetic acids, chloride containing environments. It can also be used in the application of organic and inorganic containing environments. AISI 440C Stainless Steel is highly resistive to grain boundary precipitation or sensitization.
