Refer to specific salt solution ratings. Corrosion affected by salt concentration, temperature, dissolved oxygen content and pollutants. Mine Water Fair Acidic waters containing oxidizers are highly corrosive. Corrosion affected by salt concentration, temperature, velocity, dissolved oxygen content and pollutants. Link to Active This link will always route to the current Active version of the standard. Affected by pollutants and other environmental factors.
Atmosphere, Rural Excellent Low corrosion rates, no localized attack Chlor.
Specs ASTM B187
Copper Chloride Fair Severe oxidizing environment. Road Bed Expansion Plates. May affect color or taste. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
Combining values from the two systems may result in nonconformance with the specification. Sodium Peroxide Fair Oxidizing environment Sulfur comp. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Within the text, the SI units are shown in brackets. Atmosphere, Marine Excellent Protective green basic copper chloride or carbonate patina. Careful consideration must be given to specific contaminants when selecting materials for this complex environment.
Protective green basic copper chloride or carbonate patina.
Products shall be produced in tempers O60 soft annealedand H04 hard. Hydrogen sulfide causes rapid tarnishing. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
