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.

Advanced Electropolishing Technologies Railroad Ct. The removal of soil shall be the first step prior to any further process. Printable Page Email This Page. 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.

Spark discharge and subsequent pitting shall be avoided in electrolytic systems.

ASTM B – Revision (Reapproved )

It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application of acid treatment. The blasting procedure will remove hot work scales and lubricants from titanium 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. 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.

Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces

Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the b6000. The sand selection, roughening of exposed surfaces, removal of embedded steel blasting particles, and residual stresses are all discussed. 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.

Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting may be used to remove hot work scales and lubricants from titanium surfaces. Our passivation processes remove iron and other surface contaminants from stainless steel surfaces. For chemically milled materials, salt bath conditioning 6b00 be required to remove the oxygen-contaminated layer. About Us Contact Us Sitemap. There are some restrictions to the types of materials being passivated. 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 astj resulting from heat treatment operations and foreign substances present as surface contaminants.

Titanium Strip, Foil and Coil. Our passivation processes comply with any industry or company-specific chemical passivation standards, including ASTM specifications. 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 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. All our chemical passivation treatments plus preliminary cleaning and descaling processes comply to ASTM standards.

Heavy contaminates or oxides formed by heat-treating and other high temperature operations are removed completely through pickling.

ASTM B600 – 2011 Revision (Reapproved 2017)

Historical Version s – view previous versions of standard. Visual inspection, hydrogen absorption monitoring during the cleaning process, and cleanliness evaluation by chemical milling test are discussed.

Link to Active This link will always route to the current Active version of the standard. It is usually followed by asstm alkaline conditioning and acid pickling process.

Our pickling operations involve softening the scale of acids before complete removal. ASTM B has provided three mechanical descaling methods including sandblasting, shot blasting, and vapor blasting.

We restore the component to its original mill condition. Apart from forming a corrosion resistant layer over the substrate, these chemical cleaning processes also remove material contamination that may occur in machining operations.

ASTM B is the standard guide for descaling and cleaning titanium and titanium alloy 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. This abstract is a brief summary of the asstm standard. AET has some of the largest pickling tanks in the industry to perform superior cleaning operations on huge welded structures.

Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. How to Evaluate Titanium Welding Visually?
