A494 Grade CY5SnBiM Waukesha Alloy 88

A494 Grade CY5SnBiM Waukesha Alloy 88

• Waukesha Alloy 88 was developed specifically for corrosion resistance and close operating clearance requirements of high performance rotary positive displacement pumps. Alloy 88 is a nickel based, corrosion-resistant, non-galling or seizing material. The ASTM designation is A494 Grade CY5SnBiM (UNS N26055) and the material is listed in the 3-A sanitary standards as acceptable for product contact surfaces
• Density of CY5SnBiM: 8.8g/cm³
• Corrosion resistance of Alloy 88 is approximately equal to AISI 300 series stainless steel. However, alloy 88 has limited resistance to certain aggressive chemicals that may be commonly used in contact with AISI 300 series stainless steel. Do not use alloy 88 in contact with nitric acid. Nitric acid is commonly used to passivate new installations of stainless steel equipment
• Do not allow nitric acid based passivation chemicals to contact Alloy 88 rotors. Remove the rotors during passivation and use a separate pump to circulate the passivation chemicals. Also, if nitric acid-based CIP cleaning chemicals are used, remove the rotors prior to CIP cleaning and clean them separately by hand in a mild detergent
• Spec. & standards: ASTM A494/A494M-14a
• Standard Specification for castings, nickel and nickel alloy
