Corrosion resistance of some specific materials can be enhanced with our proprietary light electropolishing method too.
Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface. Spark discharge and subsequent pitting shall be avoided in electrolytic systems. The soils, oxides and scales are resulting from heat treatment operations, manufacturing processes, or foreign substances present as surface contaminants. They may have very negative effects on the corrosion resistance, stability and quality of the finished ast products, thus, shall be removed prior to chemical milling, joining weldingplating, and fabrication.
It is usually followed by molten alkaline conditioning and acid pickling process.
Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces
This abstract is a brief summary of the referenced standard. 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. Stainless steel substrates with low levels of chromium and nickel increase the risk of flask asrm, weaken the base material, as well as damage the part during passivation.
Link to Active This link will always route to the current Active version of the standard. AET has some of the largest pickling tanks in the industry to perform superior cleaning operations on huge welded structures. Similarly, welded or brazed parts are not suited for passivation, as passivation cannot remove scale and discoloration that occurs on the “heat affected zones.
The removal of soil shall be the first step prior to any further process.
Advanced Electropolishing Technologies Railroad Ct. Printable Page Email This Page. Our passivation processes comply with any industry or company-specific chemical passivation standards, including ASTM specifications.
ASTM B – 11 Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces
The blasting procedure will remove hot work scales and lubricants from titanium surfaces. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer.
All our chemical passivation treatments plus preliminary cleaning and descaling processes comply to ASTM standards. How to Evaluate Titanium Astk Visually?
Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants. 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.
Heavy contaminates or oxides formed by heat-treating and other high temperature operations are removed completely through pickling. Historical Version s – view previous versions of standard. The sand selection, roughening of exposed surfaces, removal of embedded steel blasting particles, and residual stresses are all discussed.
It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application of acid treatment. We restore the component to its original mill condition.
ASTM B600 – 11(2017)
About Us Contact Us Sitemap. There are some restrictions to the types of materials being passivated. Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting may be used to remove hot work qstm and lubricants from titanium surfaces. Our passivation processes remove iron and other surface contaminants from stainless steel surfaces. ASTM B has provided three mechanical descaling methods including sandblasting, shot blasting, and vapor blasting. Our pickling operations involve softening the scale of acids before complete removal.
Titanium Strip, Foil and Coil. The values given in parentheses are mathematical conversions to SI units that are provided for information only and g600 not considered standard. Visual inspection, hydrogen absorption monitoring during the cleaning process, and cleanliness evaluation by chemical milling test are discussed.
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. ASTM B is the standard guide for descaling and cleaning titanium and titanium alloy surfaces. 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.
Apart from forming a corrosion resistant layer over the substrate, these chemical cleaning processes also remove material contamination that may occur in machining operations.
