ASTM 514 equivalent grade material?

[Srinivas Engr]

Dear all.

pl let me know..
wat r equivalent grade material for ASTM 514?
& where we can refer for that?
Is it only chemical composition only..
or any specs tells about this?

Regards
Srinivas

Dear Srini

From I did in past, it is allowed to substitute material when the following requirement/number of factors are met to the original mat’l (I notice this depends on Client Spec).
1. Carbon content
2. Sulfur composition
3. Phosphor composition
4. Mechanical properties i.e. yield strength, tensile strength, elongation and etc
5. Carbon equivalent (shall not exceed CEQ maximum) or PCM max
6. Impact test (if required by Client)

Have a nice day

Hello Srinivas,

 

Attached  are the compositions and the mechanical properties of all grades of ASTM A514.The back to back grades adopted for boiler and pressure vessels are classified under SA -517. You may see the comparative descriptions for  all the grades concerned.

 

Since these steels not used  for common fabrication work, one has to compare all the properties then only look for substitution. You may not get the exact equivalence and replacement , if so is intended.

 

If you have any specific issue with this steel feel free to drop a lone.

 

Thanks.

You may get Some equivalent grade of NEXTRA 40 or in this catagory

Dear Mr.Goswami   I have a component, material ASTM A 514Gr F and made by "casting" due to complex design. The thickness is 100mm. After casting, it has been given only a annealing treatment by the casting manufacturer ( @900 degrees ). I dont understand why it was not quenched and tempered. The service temperature of this component is at room temp.   Now a part of this casting has broken and i want to weld it.   I have selected E309L electrode.   Kindly let me know the PREHEAT and INTERPASS Temperature for welding this 100mm thick A514 Gr F. By calculations i have got preheat temp as 125 degrees C as there is no restraint and i will be using a basic coated electrode. Also i realise that no PWHT is required.   Kindly advise..   Regards   Prem Nautiyal (IWE) Cell: 9769316004 --- On Fri, 5/6/11, pgoswami <pgos...@quickclic.net> wrote:

Hi Prem,

 

Minimum preheat & Interpass temp. for the ASTM A514 is 110 deg. cel. , since you have using the 125 deg. cel is not an issue.

 

As you said the ,complex design, did you agreed to get the required properties by annealing treatment instead of Q &T ?

 

In my opinion, if you tested QTC properties from the casting of 100 mm thick, substitution of Heat treatment is not an issue if you can attain the required mechanical properties unless specific project restriction.  Annealed one has not good properties in thorough thick when compared to Q &T beyond 100 mm thick.

 

Annealed one have more room on further fabrication, if you intended to go PWHT.

 

Normally , less than 65 mm thick A514 & A517 classified under one group as per D1.1.

 

Thanks & Regards,
