Material Grade Characteristics
304 Stainless Steel
Standard 18-8 austenitic stainless steel
Excellent atmospheric corrosion, oxidation and fresh water resistance
Good ductility, weldability and structural stability
Cost-effective for general water, fire protection and conventional pipeline projects
316 Stainless Steel
Added molybdenum element
Superior resistance to salt spray, seawater, chloride and weak acid-base corrosion
Better anti-corrosion and high temperature performance than 304
Ideal for coastal, chemical, marine, pharmaceutical and harsh working environments
