Steel Rebar Grading between different standards
Steel Rebar Grading between different standards
(OP)
Ok so i received these steel rebars today, but i am confused on the grade and strength of the bars, as you can see from the label, the bars are B450C according. to D.M. 14.01.2008 (Italy)
but then below you can see another 6 standards with different grades. so what is the yield strength of the steel bars i have in hand now? is it 450MPa or 500MPa?
this is their catalogue

Maybe ASTM A615, Grade 60 bars has a safety factor already applied to it?
RE: Steel Rebar Grading between different standards
If I was the one getting these bars then since I am in US and we use ASTM I would only assume it's 60 ksi only because I am not familiar with all other ones listed on the tag.
However, for example: sometimes within ASTM grades steel can be double or triple graded (like HSS/Tube/PIPE members). They locally meet A35, A500B and A500C grade all of which have differed yields per AISC. I always take advantage of this and design it using 46 KSI (A500C).

One strange thing for me is the fact that the weldable bar in the US is graded as ASTM A706 not A615.....

JAE - metric is like 'English-second-language' to Americans! mPA is what milli Pascals?
Its MPa...mega Pascals.

A706 is always weldable with up to and including #6 rebar without pre-heat, and with pre-heat required for #7 to #18
A615 can be weldable but with pre-heat in all cases, 300 Deg for #6 and under, and 500 deg for #7 and larger, except if mill test reports are available and show Carbon Equivalent Content that complies with D1.4 requirements.
