b60 Our pickling operations involve softening the scale of acids before complete removal. For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer.

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

Advanced Electropolishing Technologies Railroad Ct. The removal of soil shall be the first step prior to asrm further process.

Heavy contaminates or oxides formed by heat-treating and other high temperature operations are removed completely through pickling. How to Evaluate Titanium Welding Visually? It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine b60 applicability of regulatory limitations prior to use. Apart from forming a corrosion resistant layer over the substrate, these aetm 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. It is recommended that the materials shall be subjected to soil removal prior to heat treatment or application of acid treatment.

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

The soils, oxides and scales are resulting from heat treatment operations, manufacturing processes, or foreign substances present as surface contaminants. ASTM does not give any warranty g600 or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Spark discharge and subsequent pitting shall be avoided in electrolytic systems. It is usually followed by molten alkaline conditioning and acid pickling process. AET has some of the largest pickling tanks in the industry to perform superior cleaning operations on huge welded structures. Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting may be used to remove hot work scales and lubricants from titanium surfaces.

About Us Contact Us Sitemap. Titanium Strip, Foil and Coil. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Acid etching treatment may be required following mechanical abrading or chemical conditioning of materials to completely clean the surface. The blasting procedure will remove hot work scales and lubricants from titanium surfaces. Printable Page Email This Page. 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. ASTM B is the standard guide for descaling and cleaning titanium and titanium alloy surfaces. 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. 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. Corrosion resistance of some specific materials can be enhanced with our proprietary light astk method too.

Passivation and Pickling

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. 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. There are some restrictions to the types of materials being passivated. Our passivation processes remove iron and other asrm contaminants from stainless steel surfaces.

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.
