Corrosion resistance of some specific materials can be enhanced with our proprietary light electropolishing method too. Printable Page Email This Page. Our passivation processes remove iron and other surface contaminants from stainless steel surfaces. Stainless steel substrates with low levels of chromium and nickel increase the risk of flask attack, weaken the base material, as well as damage the part during passivation.
ASTM B – Revision (Reapproved )
Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface. Apart from forming a corrosion resistant layer over the substrate, these chemical cleaning processes also remove material contamination that may occur in machining operations.
There are some restrictions to the types of materials being passivated. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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.
The blasting procedure will remove hot work scales and lubricants from titanium surfaces. The soils, oxides and scales are resulting from heat treatment operations, manufacturing processes, or foreign substances present as surface contaminants. Historical Version s – view previous versions of standard. The removal of soil shall be the first step prior to any further process.
Our passivation processes comply with any industry or company-specific chemical passivation standards, including ASTM specifications. We restore the component to its original mill condition. Our pickling operations involve softening the scale of acids before complete removal. All our chemical passivation treatments plus preliminary cleaning and descaling processes comply to ASTM standards.
Advanced Electropolishing Technologies Railroad Ct. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
AET has some of the largest pickling tanks in the industry to perform superior cleaning operations on huge welded structures. It is usually followed by molten alkaline conditioning and acid pickling process.
Spark discharge and subsequent pitting shall be avoided in electrolytic systems.
About Us Contact Us Sitemap. Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants.
Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting b60 be used to remove hot work scales and lubricants from titanium surfaces. This guide covers a cleaning and descaling procedure for the removal of ordinary shop soils, oxides, and scales from the surface of titanium or titanium alloy surface.
The sand selection, roughening of exposed surfaces, removal of embedded steel blasting particles, and residual stresses are all discussed.
This abstract is a brief summary of the referenced standard. Titanium Strip, Foil and Coil.
Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces
ASTM B has provided three mechanical descaling methods including sandblasting, shot blasting, and vapor blasting. It is recommended that the materials shall be subjected to soil removal prior aetm heat treatment or application of acid treatment. How to Evaluate Titanium Welding Visually? Link to Active This link will always route bb600 the current Active version of the standard. Visual inspection, hydrogen absorption monitoring during the cleaning process, and cleanliness evaluation by chemical milling test are discussed.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are v600, complete or up to date. Heavy contaminates or oxides formed by heat-treating and g600 high temperature operations are removed completely through pickling. They may have very negative effects on the corrosion resistance, stability and quality of the finished titanium products, thus, shall be removed prior to chemical milling, joining weldingplating, and fabrication.
This guide covers a cleaning and descaling procedure useful to producers, users, and fabricators of titanium and titanium alloys for the removal of ordinary shop soils, oxides, and scales resulting from heat treatment operations and foreign substances present as surface contaminants.
Similarly, welded or brazed parts are not suited for passivation, as passivation cannot remove scale and discoloration that occurs on the “heat affected zones. ASTM B is the standard guide for descaling and cleaning titanium and titanium alloy surfaces.
For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer.
