Premium Stainless Steel Alloys for Corrosive Environments
Our expertise focuses on two fundamental austenitic stainless steel grades:

304 Stainless Steel (CF8)

• Excellent General Corrosion Resistance: Withstands oxidizing acids and various industrial chemicals

• Good Mechanical Properties: Maintains strength and durability across temperature ranges from -425°F to 1500°F

• Superior Formability and Weldability: Allows for design flexibility and easy integration

• Non-Magnetic Properties: Ideal for electronic and scientific applications

316 Stainless Steel (CF8M)

• Enhanced Corrosion Resistance: Molybdenum addition provides superior resistance to chlorides and acidic conditions

• Improved High-Temperature Strength: Maintains structural integrity in elevated temperature applications

• Excellent Pitting and Crevice Corrosion Resistance: Perfect for marine and chemical processing environments

• Superior Stress Corrosion Cracking Resistance: Withstands harsh chemical exposures under tension

Precision Investment Casting Process
Our lost-wax casting methodology ensures superior quality and complex geometries:

Pattern and Mold Creation
