It is usually followed by molten alkaline conditioning and acid pickling process. Printable Page Email This Page. Our passivation processes comply with any industry or company-specific chemical passivation standards, including ASTM specifications. We restore the component to its original mill v600. Advanced Electropolishing Technologies Railroad Ct.

Apart from forming a corrosion resistant layer over the substrate, these chemical cleaning processes also remove material contamination that may occur in machining operations. The sand selection, roughening of exposed surfaces, removal of embedded steel blasting particles, and residual stresses are all discussed.

The removal of soil shall be the first step prior to any further astn. For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer.

It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application of acid treatment. Astmm to Evaluate Titanium Welding Visually? Link to Active This link will always route to the current Active version of the standard.

The blasting procedure will remove hot work scales and lubricants from titanium surfaces. 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.

Stainless steel substrates with low levels of chromium and nickel b6000 the risk of flask attack, weaken the base material, as well as damage the part during passivation. AET has xstm of the largest pickling tanks in the industry to perform superior cleaning operations on huge welded structures. Corrosion resistance of some specific materials can be enhanced with our proprietary light electropolishing method too.

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. About Us Contact Us Sitemap. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Our pickling operations involve softening the scale of acids before complete removal.

Passivation and Pickling

ASTM B has provided three mechanical descaling methods including sandblasting, shot blasting, and vapor blasting. The soils, oxides and scales are resulting from heat treatment operations, manufacturing processes, or foreign substances present as surface contaminants.

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 asrm use. Heavy contaminates or oxides formed by heat-treating and other high temperature operations are removed completely through pickling. Our passivation processes remove iron and other surface contaminants from stainless steel surfaces. Titanium Strip, Foil and Coil. 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 weldingastj, and fabrication.

Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface. 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.

Historical Version s – view previous versions of standard. Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting may asstm used to remove hot work scales and lubricants from titanium surfaces.

This abstract is a brief summary of the referenced standard. Visual inspection, hydrogen absorption monitoring during the cleaning process, and cleanliness evaluation by chemical milling test are discussed. B60 post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants.

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.

ASTM B is the standard guide for descaling and cleaning titanium and titanium alloy surfaces.

ASTM B – Revision (Reapproved )

Spark discharge and subsequent pitting shall be avoided in electrolytic systems. All our chemical passivation treatments plus preliminary cleaning and descaling processes comply to ASTM standards. There are some restrictions to the types of materials being passivated.
