Standard Gasket Material

Carbon Steel

Commercial quality sheet steel with an upper temperature limit of approximately 1000º F., particularly if conditions are oxidizing. Not suitable for handling crude acids or aqueous solutions of salts in the neutral or acid range. A high rate of failure may be expected in hot water service if the material is highly stressed, Concentrated acids and most alkalies have little or no action on iron and steel gaskets which are used regularly for such services.

304 Stainless Steel

 An 18-8 (Chromium 18-20%, Nickel 8-10%) Stainless with a maximum recommended working temperature of 1400º F

 At least 80% of applications for non-corrosive services can use Type 304 Stainless in the temperature range of -320 F to 1000º F.

 Excellent corrosion resistance to a wide variety of chemicals.

 Subject to stress corrosion crackling and to intergranular corrosion at temperatures between 800º F to 1500º F in presence of certain media for prolonged periods of time.

316 Stainless Steel

 An18-12 Chromium-Nickel steel with approximately 2% of Molybdenum added to the straight 18-8 alloy which increases its strength at elevated temperatures and results in somewhat improved corrosion resistance.

 Has the highest creep strength at elevated temperatures of any conventional stainless type.

 Not suitable for extended service within the carbide precipitation range of 800º F to 1650º F. when corrosive conditions are severe.

 Recommended maximum working temperature of 1400º F.

316L Stainless Steel

 Continuous maximum temperature range of 1400º F -1500º F.

 Carbon content held at a maximum of .03%.

 Subject to a lesser degree of stress corrosion cracking and also to intergranular corrosion than Type 316.

321 Stainless Steel

 An 18-10 Chromium-Nickel steel with a Titanium addition.

 Type 321 stainless has the same characteristics as Type 347.

 The recommended working temperature is 1400º F to 1500º F. and in some instances 1600º F
