Dear Sir,
Greetings of the day!
I have one query, I have done Tensile test for full Pipe specimen OD 25.7mm and thk 2.1 mm material SS 304L according to EN standard by calculating gauge length by consideration the OD of pipe with formula 5.65 x square root of Area which is coming 130 mm rounded off . In UTM machine I have select hollow pipe section and tensile strength is coming automatically with these settings.
But elongation is coming 32% and minimum required is 40%. We have done test by pressing the pipe ends.
Kindly let me know where is actual problem can oocurs.
I will be thankful to you.
Best Regards,
Mohit Aggarwal
