Selection decision criteria
Core rules for matching stainless alloys to plant conditions and mechanical requirements.
Molybdenum content inhibits pitting caused by saline solutions, brackish water, and chlorinated cleaning agents.
Carbon content below 0.03% prevents chromium carbide formation along grain boundaries, protecting joint strength.
Copper and high nickel addition provide stable passivation against reducing mineral acids and high-chloride liquors.
Provides the optimum balance of mechanical rigidity, cleanability, and overall procurement economy.
