High Strength Bolts Coatings

But there are some doubts. No metric equivalents are presented in this specification. Serge- We have very little experience with Dacromet coating. 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.

As for the thickness of both coatings, F grade 3 specified a coating thickness of 0. ASTM does not give any warranty express or implied or make any representation asstm the contents of this abstract are accurate, complete or up to date.

Is fluorocarbon coating acceptable to A bolts for corrosion prevention? Your first asm, is it appropriate to specify ASTM F Grade 3would be best answered by an engineer familiar with the coating and the application.

Leave this field empty. Depending on the amount of corrosive forces at work in the application, F may be sufficient, but it may not. The corrosion protection asgm by F in those cases would be superior to nothing at all.

High Strength Bolts Coatings – Portland Bolt

No other units of measurement are included in this standard. Consulting a structural engineer involved on the project is always the best solution. Alkaline cleaning or vapor degreasing is required along with shot blasting to c1136 rust or scale.

The basecoat can contain chrome C or be non-chrome NC. Due to hydrogen embrittlement concerns ASTM recommends against hot-dip galvanizingmechanical deposition, or electroplating with zinc or other metallic coatings on high strength bolts ultimate tensile strengths that zstm ksi.

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

Jovito- We would be happy to quote your specific bolting needs if you want to send us a list of the bolts you are looking for. I am using A grade BC and need a smooth finish with minimal irregularities.

I suppose they are similar to painting. We assumed that the properties on the bolts is not affected but the final tension might be change? Pierre-Paul — The properties of the f1163 and the final tension should not be impacted.

What corrosion-resistant coatings are available for high-strength over ksi bolts? Since we are using A bolts in asttm structure, we have to propose a replacement. Your email address will not be published. Leave a Reply Cancel reply Your email address will not be published. So what are the alternatives to provide corrosion resistance for A structural bolts? If so, did the tension will be higher? Since the Dacromet f11336 Magni will be in contact with one another, Are they compatible with one another?

This fastener is made from weathering steel which is inherently corrosion resistant. A coatings engineer may choose to allow an exception in some cases, but ASTM will not officially sanction any coatings that are not approved by the F16 committee. Hi, Recently we were informed that Dacromet coating is being phased out.

They were used to in flange type splices of two tubular monopole sections. Historical Version s – view previous versions of standard.

We are not sure how fragile the coating is during installation. Hello, We have specified A Dracomet coated bolts for a telecommunications monopole in Canada.

The tightening torque may vary from plain finish or other coatings, but the bolt should still function the same. F Grade 3, commonly known as Dacromet. Work Item s – proposed revisions of this standard.
