Revision 0
Note: k (New)
V+Nb+Ti shall not exceed 0.15%
Cu+Ni shall not exceed 0.40%
Al/N ratio shall be min. 2
Note: l (New)
If alloying elements other than those specified in Table 5 above are added to the steel, the
limits of the additional components shall be agreed with the Purchaser.
Note: m (New)
Minimum for Silicon is not applicable for Aluminium killed steel.
For heat analysis and product analysis, all the elements listed in Table 5 of this
specification shall be analysed and reported, even if those are not purposely added but are
present as residuals only.
9.2.4 Boron content shall be considered in CE (Pcm) formula even if it is less than 0.0005%.
For pipes of all grades, size and wall thickness, Carbon Equivalent shall comply with the
following limits:
CE (Pcm) 0.20
9.2.5 For pipes of all grades, size and wall thickness, Carbon Equivalent shall comply with the
following limits:
CE (IIW) 0.40
9.3 TENSILE PROPERTIES
The tensile tests and properties shall conform to the requirements of API 5L for the grade
of pipe specified on the purchase order and as modified herein.
The actual yield strength shall be as close as possible to the specified minimum yield
strength (SMYS) but in no case it shall exceed the limits specified here under:
API Spec 5L Grade
Permissible in excess of SMYS, psi (MPa)
Up to and including X46 19,000 (131)
X52 to X65 22,000 (152)
X70 20,000 (138)
The ratio of body yield strength and body ultimate tensile strength of each test pipe on
which body yield strength and body ultimate tensile strength are determined, shall not
exceed 0.90.
