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.

The sand selection, roughening of exposed surfaces, removal of embedded steel blasting particles, and residual stresses are all discussed. The blasting procedure will remove hot work scales and lubricants from titanium surfaces.

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

How to Evaluate Titanium Welding Visually? 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. Our pickling operations involve softening the scale of acids before complete removal.

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

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

The b6000 given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Historical Version s – view previous versions of standard.

Advanced Electropolishing Technologies Railroad Ct. Mechanical descaling methods such as sandblasting, shot blasting, and vapor blasting may be used to remove hot work scales and lubricants from titanium surfaces. The soils, oxides and scales are resulting from heat treatment operations, manufacturing processes, or satm substances present as surface contaminants.

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

For chemically milled materials, salt bath conditioning may be required to remove the oxygen-contaminated layer. Acid etching treatment may be required following mechanical abrading or chemical conditioning of h600 to completely clean the surface.

It is usually followed by molten alkaline conditioning and acid pickling process. ASTM B has provided three mechanical descaling methods including sandblasting, shot blasting, and vapor blasting.

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. This guide covers a cleaning and descaling astk 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.

Apart from forming a corrosion b6600 layer over the substrate, these chemical cleaning processes also remove material contamination that may occur in machining operations. Corrosion resistance of ashm specific materials can be enhanced with our proprietary light electropolishing method too.

ASTM B600 – 11(2017)

Our passivation processes remove iron and other surface contaminants from stainless steel surfaces. Printable Page Email This Page. There are some restrictions to the types of materials being passivated. All our chemical passivation treatments plus preliminary cleaning and descaling processes comply to ASTM standards.

ASTM B is the standard guide for descaling and cleaning titanium and titanium alloy surfaces. We restore the component to its original mill condition. The removal of soil shall be the first step prior to any further process. 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. Our passivation processes comply with any industry or company-specific chemical passivation standards, including ASTM specifications.

Recommended post treatment of shot or abrasive blasted titanium surfaces may include acid pickling to ensure complete removal of surface contaminants. Titanium Strip, Foil and Coil.
