Service recommendations must take into consideration specific environmental conditions which often have a profound influence on the nature of the corrosive service and hence on the behaviour of materials. Temperature, aeration, inhibiting or accelerating contaminates, and velocities are examples of the factors of ten encountered. Occasionally a user's experience, under identical or similar conditions, may indicate an exception to a recommendation in the table below. In such a case further investigation is advised.

 

Acetaldehyde A Glucose A Propyl Alcohol A
Acetic Acid 10% A Glycerine A Pyridine B
Acetic Acid Vapours B Glycols A Sea Water A
Acetone A Hydrogen Sulphide (Dry) B Silicones A
Acetylene A Ketones B Silver Nitrate A
Alcohols A Lime B Soaps A
Aluminium Sulphate A Lithium Bromide B Sodium Acetate A
Ammonia (Gas) A Lithium Chloride B Sodium Aluminate B
Ammonium Bicarbonate A Magnesium Carbonate A Sodium Bicarbonate A

Ammonium Nitrate 10% B Methyl Alcohol A Sodium Chromate B
Ammonium Sulphate A Methyl Ethyl Ketone A Sodium Hydroxide < 30% A
Amyl Acetate B Methyl Isobutyl Ketone B Sodium Hydroxide > 30% B
Barium Chloride A Milk A Sodium Metaphosphate A
Barium Hydroxide A Molasses B Sodium Metasilicate B
Barium Nitrate A Nickel Nitrate 5 to 10% A Sodium Nitrate B
Beer 71% A Nickel Sulphate A Sodium Nitrite B
Boric Acid B Phenol B Sodium Perborate B

Gelatine A Potassium Sulphate A Zinc Sulphate B

 
Key A = Substantial resistance. Satisfactory service can be expected
B = Moderate resistance. May be used where a somewhat limited life would be acceptable
