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. 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.
All our chemical passivation treatments plus preliminary cleaning and descaling processes comply to ASTM standards.
Our passivation processes remove aatm and other surface contaminants from stainless steel surfaces. Our pickling operations involve softening the scale of acids before complete removal.
Asmt discharge and subsequent pitting shall be avoided in electrolytic systems. 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 – Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces
AET has some of the largest pickling tanks in the industry to perform superior cleaning operations on huge welded structures. How to Evaluate Titanium Welding Visually?
The soils, oxides and scales are resulting from heat treatment operations, manufacturing processes, or foreign substances present as surface contaminants. Our passivation processes comply with any industry or company-specific chemical passivation standards, including ASTM specifications. 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 B600 – 2011 Revision (Reapproved 2017)
Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants. Heavy contaminates or oxides formed by heat-treating and other high temperature operations are removed completely through pickling.
Visual inspection, hydrogen absorption monitoring during the cleaning process, and cleanliness evaluation by chemical milling test are discussed. ASTM B has provided three mechanical descaling methods including sandblasting, shot blasting, and vapor blasting. Corrosion resistance of some specific materials can be enhanced with our proprietary light electropolishing method too. The blasting procedure will remove hot work scales and lubricants from titanium surfaces.
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. Historical Version s – view previous versions of standard.
ASTM B600 – 11(2017)
The sand selection, roughening of exposed surfaces, removal of embedded steel blasting particles, and residual stresses are all discussed. We restore the component to its original mill condition. For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer.
Printable Page Email This Page. Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the 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.
It is usually followed by molten alkaline conditioning and acid pickling process. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Titanium Strip, Foil and Coil.
The removal of soil shall be the first step prior to any further process. Advanced Electropolishing Technologies Railroad Ct.
ASTM B – Revision (Reapproved )
Apart from forming a corrosion resistant layer over b60 substrate, these chemical cleaning processes also remove material contamination that may occur in machining operations. 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.
ASTM B is the standard guide for descaling and cleaning titanium and titanium alloy surfaces.
This guide covers a cleaning and descaling procedure useful to producers, users, and fabricators of titanium and titanium alloys b6000 the removal of ordinary shop soils, oxides, and scales resulting from heat treatment operations and foreign substances present as surface contaminants.
This abstract is a brief summary of the referenced standard. About Us Contact Us Sitemap. 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.
Similarly, welded or brazed parts are not suited for passivation, as passivation cannot remove scale and discoloration that occurs on the “heat affected zones.
