What core advantages does advanced stainless steel have over conventional stainless steel?

Ordinary stainless steel like 304 and 316 suffers pitting and stress cracking quickly under concentrated chloride, high temperature or sulfur-containing flue gas. Advanced stainless steel with elevated alloy content maintains intact passive films under such harsh conditions, extending component service life by several times. Duplex and super duplex versions own far higher tensile strength, allowing thinner wall designs to reduce equipment weight and material costs. Many grades also possess better thermal fatigue resistance to withstand repeated heating and cooling cycles in energy and chemical facilities.
