It is informational only and not an official qstm of the standard; the full text of the standard itself must be referred to for its use and application.

The removal of soil shall be the first step prior to any further process. Our pickling operations involve softening the scale of acids before complete removal. It is usually followed by molten alkaline conditioning and acid pickling process.

Printable Page Email This Page. AET has some of the largest pickling tanks in the industry to perform superior cleaning operations on huge welded structures. 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.

Heavy contaminates or oxides formed by heat-treating and other high temperature operations are removed completely through pickling. This abstract is a brief summary of the referenced standard.

ASTM B – 11 Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces

Apart from forming a corrosion resistant layer over the substrate, these chemical cleaning processes also remove material contamination that may occur in machining operations. Advanced Electropolishing Technologies Railroad Ct.

Link to Active This link will always route to the current Active version of the standard. Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface.

Similarly, welded or brazed parts are not suited for passivation, as passivation cannot remove scale and discoloration that occurs on the “heat affected zones. 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.

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

Historical Version s – view previous versions of standard. Spark discharge and subsequent pitting shall be avoided in electrolytic systems. Asrm sand selection, roughening of exposed surfaces, removal of embedded steel blasting particles, and residual stresses are all discussed.

Passivation and Pickling

It is the responsibility of the user of this standard to consult and establish appropriate safety asstm health practices and determine the applicability of regulatory limitations prior to use.

For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer. Bb600 soils, oxides and scales are resulting from heat treatment operations, manufacturing processes, or foreign substances present as surface contaminants.

There are some restrictions to the types of materials being passivated. 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.

ASTM B – Revision (Reapproved )

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

ASTM does not give any warranty express or implied or make any representation that astj contents of this abstract are accurate, complete or up to date.

The blasting procedure will remove hot work scales and lubricants from titanium surfaces. Corrosion resistance of some specific materials can be enhanced with our proprietary light electropolishing method too.

It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application adtm acid treatment. How to Evaluate Titanium Welding Visually?

ast We restore the component to its original mill condition. Titanium Strip, Foil and Coil. 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 is the standard guide for descaling and cleaning titanium and titanium alloy surfaces.
