Grades 321 (titanium-stabilized) and 347 (niobium-stabilized) contain elements that tie up carbon before it can react with chromium, drastically reducing sensitization at operating temperatures.

It defines exactly how much chloride, temperature, and H2S a metal can take before it begins to die.

Imagine a refinery hydrotreater. During operation, the stainless steel components are covered in iron sulfide scale. When the unit is shut down for maintenance, the temperature drops, and air (oxygen) enters. Moisture from the air combines with the sulfide scale to form polythionic acid. nace sp0170 pdf
