Re: [MW:34814] Clarification in Rate of heating and cooling.

Max heating rate: 222C/hr /max metal thickness (in inches)

Max cooling rate: 280C/hr / max metal thickness (in inches) 

So your PQR thickness is 50 mm => 2 inch. 

So, In your case:

 max heating rate is 111C/hr

 Max cooling rate is 140 C/hr. 

Thanks

dear expert

I have to do WPS and PQR details given below

Test coupon

Thickness -50 mm

Material - IS 2062 E 350 C 

Code - ASME 

Position - 3G

Process - SMAW 

Electrode - E-7018

Impact = -20C @ 27J

Stress Relieving - 605+/- 10c

Rate of heating/cooling- 100c/hr

Whether if Rate of heating / cooling is 100c/hrs will it affect the test result both UTS and Impact properties?

As per UCS 56 ASME SEC 8 div 1 Max rate of heating and cooling 222c/hrs divided by max.metal thickness.

As my client need Rate of heating and cooling 100c/hrs.

Plz kindly clarify.
