The chemical compatibility of LDPE and HDPE on this chart is tested at 20°C:and 50°C:for 7 days and 30 days (if applicable) with constant exposure. LDPE & HDPE resistance listed by chemical. 1.4-dioxane. LDPE / HDPE at 20°C:little or no damage after 30 days. LDPE at 50°C:shows some effect after 7 Chemical Compatibility Database from Cole-ParmerThe information in this chart has been supplied to Cole-Parmer by other reputable sources and is to be used ONLY as a guide in selecting equipment for appropriate chemical compatibility. Before permanent installation, test the equipment with the chemicals and under the specific conditions of your application. Ratings of chemical behavior listed
General corrosion . Stainless steels are defined as being characterized by particularly high resistance to chemical attack by aqueous media. In general, they contain at least 12% by weight of chrome and a maximum of 1.2% carbon. Corrosion behaviour of AISI type 304L stainless steel in Jan 01, 2011 · Research highlights Corrosion behaviour of 304L stainless steel has been evaluated in the presence of oxidizing species in nitric acid medium. No significant change in corrosion potential even with increase in temperature and nitric acid concentration in presence of oxidizing ions. Faster passive film dissolution as indicated by low film polarization resistance, with increase in nitric acid
Aug 01, 1998 · The corrosion rates of AISI 304L and 316L stainless steels prepared by powder metallurgy (P\M) have been studied by continuous electrochemical methods, in different concentrations of inorganic acid solutions (sulphuric and phosphoric) at room temperature (T = 298 K).For comparison purposes, a simultaneous study was carried out on similar composition cast AISI 304L and AISI 316L Corrosion tables Sandvik Materials TechnologyThe corrosion data in this section is mainly based on the results of general corrosion laboratory tests, which are not strictly comparable with actual service conditions.The corrosion tables provide an initial guide to the selection of materials and are intended to facilitate understanding of the different types of corrosion damage that can arise due to poor material selection.
Hydrocloric acid Stainless generally is not recommended except when solutions are very dilute and at room tem- perature. "Mixed acids" There is usually no appreciable attack on Type 304 or 316 as long as sufficient nitric acid is present. Nitric acid Type 304L or 430 is used. Phosphoric acid Type 304 is satisfactory for storing cold phosphoric Pickling & Passivation of STAINLESS STEEL 304 and 316 L Pickling and Passivation of 304 and 316L Grade SS Fabrications are BRITOSS Normal Range. For all other grades the product formulation shall have to be developed. MOST IMPORTANT Points to be Noted before undertaking PICKLING and PASSIVATION of SS 304 316L :Perform the process in areas open to sky or well VENTILATED AREAS.
The 304 types are preferable to 316 types for nitric acid applications however. This is an exception to the 'general rule' for stainless steels where the 316 types are normally found to be more corrosion resistant than 304 types. Over 95% concentration, aluminium alloys should be Shield-Bright 316LShield-Bright 316L was developed for the welding of Type 316L stainless steel but can be used for other stainless steels including Types 316 and 304L. In a few cases, e.g. nitric acid service, Shield-Bright 316L should not be used to weld 304L. It contains molybdenum which resists pitting corrosion induced by sulphuric and sulphurous acids, chlorides and cellulose solutions.
Another issue people struggle with concerning nitric acid is whether they should use the low-carbon grades:304L, 316L or the cast equivalents CF3 and CF3M. The concern is that nitric acid is a strong oxidizing acid that can cause intergranular corrosionone way to minimize the susceptibility to intergranular corrosion is to use the low Stainless Steel Chemical Compatibility ChartStainless Steel Chemical Compatibility Chart:Check the chemical compatibility of Stainless Steel with various chemicals, solvents, alcohols and other products..
