What do you mean 321H stainless steel?
The SS 321H is intended for use in a wide range of temperatures, from 800 to 1500 degrees Fahrenheit, where carbide precipitation can occur. It is stabilised against carbide precipitation. When it is annealed and can only be toughened by cold working it cannot be magnetic.
What is Different in 321 and 321H?
Quantity of carbon in each metal determines the distinction between grades 321 and 321H. While 321H has between 0.04 percent and 0.10 percent carbon, 321 has a maximum carbon content of 0.08 percent. They both have phosphorus of 0.045 percent, silicon 0.75 percent, and manganese at a maximum 2.0 percent.
