Hi The maximum stress and strain rate limits given in ASTM A370 paragraphs 11.4.1-11.4.3. The stress or strain rate influences the value of the material strength. A faster strain rate will yield larger strength values, and conversely, slower rates of testing will produce lower values. However to provide a consistent testing method , an elastic loading rate of 50 ksi per minute is to be used until after strain hardening. Regards Prem Nautiyal

What is the speed of tensile test for Procedure qualification as per section IX? i read some coads they recommended for some speed of tensile test,is it mandatory to follow or we can do at any speed? -- Regards, Pushpraj Anand -- To post to this group, send email to materials-welding@googlegroups.comTo unsubscribe from this group, send email to materials-welding+ unsubscribe@googlegroups.comFor more options, visit this group's bolg at http://materials-welding.blogspot.com/The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents.
