[MW:13756] RE: 13746] TURBALOY® 17-22 (US WELDING)

This is a specialty filler metal, 1¼Cr-½Mo base with the addition of vanadium and high carbon content (relative to most filler metals).  This material does not conform to any AWS/ASME  classification.  Typical applications are listed in the US Welding Corp. literature.  See:   http://www.usweldingcorp.com/TDS/tds6458.pdf

 

It is used for welding and repair of similar materials in turbines etc.

Hi, Experts,
Could anyone teach me what the TURBALOY® 17-22 material is?
I can not find the proper AWS code for this material.

this datasheet shows us nothing! (below link)

Thanks!!

 

Best regards

Re: [MW:13754] RE: 13484] Pre-heating for cutting

I do not remember seeing any where in the Codes, but some specifications do mention aboout this.

 

Also this will remain aa a properiatry item of some good fabricators.

Dear Gerald Yes, it is often recommended as good workmanship practices but is there anyware in Codes required as mandatory requirement? Thanks Ganesan

For carbon steels upto certain thickness it is not required.

Only when the thickness is very high and for Chrome-moly steels it is recommended to preheat the base material before cutting to avoid formation of undesirable phases which leads to cracking. Preheating before cutting will result in grain coarsening and impair the Impact properties.

Moreover it is always recommended to grind the HAZ of the Gas cut surfaces.

Perfect. To add more on this:

Basically this becomes more and more stringent, in case of low temp. steels, wherein the grain coarsening is detrimental to it's Impact ( Toughness ) properties. Also, Preheating before flame cutting is required to decrease the thermal gradient which eventually decreases the chances of grain coarsening & also reduces thermal shock or any initiation of micro fissuries leading to cracks latter. Workshop remedy is: we ask to remove the HAZ formed by flame cutting,  by grinding the skin of the flame cut edge preparation.  Offcourse, This stringent practice is generally not required for general Mild steels grades of steel.

Dear all,

 

 

The purposes of preheat are to avoid crack due to sudden heating and for wide heat affected zone,so in my openion preheating is required for both cutting and welding.

Dear All,

 Beyond all the technical aspects, small logic for this situation….

This is only my view…

 

After cutting the edges are again welding to some part / connection(say pipe, fitting, flange, etc or leaving like that) in all the cases if welding is going to do it will be again preheat and PWHT after welding so any thermal shocks will be relived during PH, PWHT,

 

So I think no need of pre heating.

Dear Experts,

 

I need your help for this subject, We are fabricating some piping as per B31.3, the material ASTM A106 Gr.B, 8"Sch-XXS and 160 and we are doing preheat and PWHT for welding, but my enquiry pre heat is required for cutting also? It is mentioned in any code or any other were? Please help me

[MW:13751] RE: 13739] How to reduce SA517 hardness

Dear sir,

The filler material you mention is a filler metal for high strength steel
and SA-517 in my opinion is a mild carbon steel (max 480 - 620 MPa) so in my
opinion this is not the correct filler metal.

Onderwerp: [MW:13739] How to reduce SA517 hardness

Dear Sir,
We are using one material which is equivalent to SA-517 material ( Pressure
vessel plates, alloy steel, high strength, quenched & tempered ). with
electrode E-11018M. Climatic condition of the environment is minus 5 degree
Centigrade to plus six degree Centigrade.Parent material hardness is 230 BHN
but weld material hardness is coming approx 400 BHN which is not
acceptable. We are properly maintaining preheating i.e 250 degree
Centigrade as well as interpass temperature is 150 degree centigrade.
Pls guide me how can i reduce this material hardness.
Regards
Pradip
