It is h600 followed by molten alkaline conditioning and acid pickling process. The sand selection, roughening of exposed surfaces, removal of embedded steel blasting particles, and residual stresses are all discussed.
Titanium Strip, Foil and Coil. AET has some of the largest pickling tanks in the industry to perform superior cleaning operations on huge welded structures. Printable Page Email This Page.
ASTM B is the standard guide for descaling and cleaning titanium and titanium alloy surfaces. The soils, oxides and scales are resulting from heat treatment operations, manufacturing processes, or foreign substances present as surface contaminants. Corrosion resistance of some specific materials can be enhanced with our proprietary light electropolishing method too.
For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer. 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.

ASTM B – Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces
The removal of soil shall asstm the first step prior to any further process. All our chemical passivation treatments plus preliminary cleaning and descaling processes comply to ASTM standards. They may have very negative effects on zstm corrosion resistance, stability and quality of the finished titanium products, thus, shall be removed prior to chemical milling, joining weldingplating, and fabrication.
Apart from forming a corrosion resistant layer over the substrate, these chemical astj processes also remove material contamination that may occur in machining operations. 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. 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.
Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface. This abstract is a brief summary of the referenced standard.
ASTM B – Revision (Reapproved )
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. Our passivation processes comply with awtm industry or company-specific chemical passivation standards, including ASTM specifications.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
About Us Contact Us Sitemap. 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. There are some restrictions to the types of materials being passivated. It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application of acid treatment.
Heavy contaminates or oxides formed by heat-treating and other high temperature operations are removed completely through pickling.
We restore the component to its original mill b6000.
The blasting procedure will remove hot work scales and lubricants from titanium surfaces. Link to Active This link will always route to the current Active version of the standard. Spark discharge and subsequent pitting shall be avoided in electrolytic systems.
Visual inspection, hydrogen absorption monitoring during the cleaning process, and cleanliness evaluation by chemical milling test are discussed. Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants.
How to Evaluate Titanium Welding Visually? Similarly, welded or brazed parts are not suited for passivation, as passivation cannot remove scale and discoloration that occurs on the “heat affected zones. 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.
Passivation and Pickling
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.
Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting may be used to remove hot work scales and lubricants from titanium surfaces. Historical Version s – view previous versions of standard.
