Low in yield strength,
tensile strength and elongation
|
High in yield strength,
tensile strength and elongation because of superior TMT
process used |
Not anti-corrosive

cleaner steel, presence of martensite layer on outer
surface and formation of protective scale film due to
water quenching |
No test certificate issued
|
Test certificate issued
with respect to each supply |
