ASTM B600 – 2011 Revision (Reapproved 2017)
We restore the component to its original mill condition. It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application of acid treatment. 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 comply with any industry or company-specific chemical passivation standards, including ASTM specifications. Our pickling operations involve softening the scale of acids before complete removal. Visual inspection, hydrogen absorption monitoring during the cleaning process, and cleanliness evaluation by chemical milling test are discussed.
The removal of soil shall be the first step prior to any further process. Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface.
It is the sstm 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.
Advanced Electropolishing Technologies Railroad Ct. About Us Contact Us Sitemap. For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer.
ASTM B – Revision (Reapproved )
The sand selection, roughening of exposed axtm, removal of embedded steel blasting particles, and residual stresses are all discussed. AET has some of the largest pickling tanks in the industry to perform superior cleaning operations on huge welded structures.
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.
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.
Spark discharge and subsequent pitting aztm be avoided in electrolytic systems. Printable Page Email This Page. Stainless steel substrates with low levels of chromium and nickel increase the risk of flask attack, weaken the base material, as well as asfm the part during passivation. Corrosion resistance of some specific materials can be enhanced with our proprietary light electropolishing method too.
ASTM B – Standard Guide for Descaling and Cleaning Titanium and Titanium Alloy Surfaces
It is usually followed by molten alkaline conditioning and acid pickling process. Titanium Strip, Foil and Coil. 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.
Apart from forming a corrosion resistant layer over the substrate, these chemical cleaning processes also remove material contamination that may occur in machining operations. Our passivation processes remove iron and other surface contaminants from stainless steel surfaces.
This abstract is a brief summary of the referenced standard. Heavy contaminates or oxides formed by heat-treating and other high temperature operations are removed completely through pickling. Similarly, welded or brazed parts are not suited for passivation, as passivation cannot remove scale and discoloration that occurs on the “heat affected zones. Historical Version s – view previous versions of standard. ASTM B is the standard guide for descaling and cleaning titanium and titanium alloy 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, xstm weldingplating, and fabrication. The blasting procedure will remove hot work scales and lubricants from titanium surfaces. 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.
This guide covers a cleaning awtm descaling procedure for b6000 removal of ordinary shop 6b00, oxides, and scales from the surface of titanium or titanium alloy surface. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants.
ASTM B has provided three mechanical descaling methods including sandblasting, shot blasting, and vapor blasting. All our chemical passivation treatments plus preliminary cleaning and descaling processes comply to ASTM standards.
