SS 321 is the stabilized and versatile grade of SS 304. The good mixture of chromium and nickel in the grade with slight amount of titanium protect it from intergranular corrosion resistance which can possibly occur after the heat treatment process. The grade offers good strength and resistive property to various forms of corrosions occurring in environment and in aqueous. Beyond this, the grade offers good forming characteristics, does not require any annealing after the welding process and exhibits great hardness in high temperature environment. 321 grades shows high durability, good resistance to corrosion and strength even when exposed in cryogenic temperatures.
Talking about the 321H SS grade, it is a high carbon version of stainless steel 321. Furthermore, the 321H is a stabilized version which is achieved by the addition of niobium which resists intergranular corrosion. The grade is suitable to withstand in high temperature and pressure due to its elevated carbon levels. 321H grade exhibits good resistance against acidic environment. When in lower temperature, the grade exhibits good resistance and also the grade can withstand up to 20% of acidic solutions.
