[MW:9610] RE: 9562] PCM (Parameter Crack Measurement)

Hi Firman,

 

See the attached article for your reference on PCM.This formula is a Japanese equivalent of IIW Carbon Equivalent formula. I would think this formula  works better for HSLA or other micro alloyed steels, or typically for pipeline steels.

 

This article explains the pros and cons of all 3 popular formula for calculation of preheating temperature.

 

Feel free ask any queries, if you wish to.

 

Thanks.
