(a) All requests, reports, applications, submittals, and other communications to the Administrator pursuant to this part shall be submitted in duplicate to the appropriate Regional Office of the U.S. Environmental Protection Agency to the attention of the Director of the Acrylite PLUS® Norva PlasticsThis data was realized at test temperature 68°F. (20°C) and 50% relative humidity. Results vary depending on the temperature and moisture content of the materials. In practice, resistance is dependant on internal and external stresses as well as the method of fabrication. We recommend appropriate testing. Chemical Resistance Alloy 347/347H Heat Resistant Stainless Steel Plate Alloy 347 also performs somewhat better than Alloy 321 in strongly oxidizing environments up to 1500°F (816°C). The alloy can be used in nitric solutions, most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and

Some gloves also provide permeation data per ASTM F3 (intermittent chemical contact). For both test methods, normalized breakthrough time (the time at which the permeation rate is equal to 0.1 ug/cm 2 /min) are reported in minutes.

STAINLESS STEEL FABRICATION - MAFIADOC.COM

The standard nitric acid passivating solution is made up and used as follows:10 to 15 percent by volume of nitric acid (HNO3) in water. Quickest and best passivation results if used at 150°F (65°C) for the austenitic (300 series) stainless steels, and 120°F (50°C) for the ferritic and martensitic (400 series) plain chromium stainless steels. Sanicro® 28 Sandvik Materials TechnologyIn nitric acid Sanicro ® 28 performs also very well. In test according to ASTM A262 Practice C (Huey test, 5x48 h in boiling 65% HNO 3 ) corrosion rates lower than 0.15 mm/year (6 mpy) are obtained. The high alloying contents of chromium and nickel give Sanicro ® 28 considerably better resistance to sodium hydroxide than standard stainless Sanicro® 41 Sandvik Materials TechnologySanicro ® 41 has significantly better corrosion resistance in formic acid than standard austenitic stainless steels. The results of corrosion tests in nitric acid are tabulated below. Resistance to sulfuric acid is illustrated in Figure 1. It should be noted that the corrosiveness of sulfuric acid

US6709528B1 - Surface treatments to improve corrosion

A method of enhancing the corrosion resistance of an austenitic steel includes removing material from at least a portion of a surface of the steel such that corrosion initiation sites are eliminated or are reduced in number relative to the number resulting from processing in a conventional manner. Material may be removed from the portion by any suitable method, including, for example, grit US7144637B2 - Multilayer, corrosion-resistant finish and The present invention provides a black, chrome-free, multilayer corrosion protection finish designed to meet extended corrosion properties. This corrosion-resistant finish is engineered to meet a minimum of 500 salt spray testing hours to white corrosion, and 1500 salt spray testing hours to red corrosion when tested to ASTM B117 standards.
