What is Stainless Steel 440A, 440B, 440C, 446 Round bar ?
Grade 440A is a high carbon version designed as stainless with some excellent properties such as good durability, and high corrosion resistance over various atmospheres. However, maximum corrosion resistance can only be obtained via stress relieving or hardening the material grade. SS 440A is magnetic in nature under annealed as well as hardened conditions.
SS 440B Round bars are martensitic steel, which also have higher carbon proportion to bear little similar properties of the SS 440A. SS 440B has limited resistance from corrosive environments and enough strength to survive against moderate temperature ranges. SS 440b bars is a chromium based crystalline nature steel bars that even enhance its further resistance as well.

SS 440C is also similar to the first 2, that means it also has higher resistance from corrosion and relatively excellent strength because of the higher carbon proportion into the material. Apart from corrosion, SS 440C also has good wear resistance and excellent properties only after the heat treatment. SS 440 round bars can survive from a high temperature environment and hence are used in several applications and multiple industries such as paper and pulp industries, power plant industries, chemical processing, petrochemical industries, food processing, and so on. SS 440C can also resist chlorine and oxidizing media under room temperature or abnormal temperatures. However, the utilization of SS 440 round bars takes place across sea and marine industries because these bars cannot survive crevice and pitting corrosions.
