Remark
- Carbon Equivalent (%) = C+Mn/6 + Si/24 +Ni/40 +Cr/5 +Mo/4 +V/14 (JIS Standard)
- Carbon Equivalent (%) = C+Mn/6 + (Cr +Mo+V)/5 + (Ni +Cu)/15 (AS,ASTM
Standard)
- Chemical Composition on sensitivity of welding crack =C + Si/30 +Mn/20 + Cu/20
+ Ni/60 + Cr/20 + Mo/15 + V/10 + 5B
- Bend test on material grades SS400, SS490, SS540
- Additional chemical composition controls for material under grade A992 are as
follows:
Ni (max) = 0.45 , Cr (max.) =0.35 , Mo(max) =0.15 and mn/S (min.) = 20
* : Nitrogen control exclude.

Remark
A :Impact test on material grades SM400,SM490, SM520,SM400B,SM490YB,
SN400B,SN490B, 43C and 50C with thickness > 12 mm. at 0 C
B :Impact test on material grades 43B, 50B, S275JR with thickness > 12mm. at 20 C
C :It is permissible to vary the carbon and manganese contents (ladle analysis) for
grades 50B and 50C on the basis of an increase of 0.06% manganese content for
each decrease of 0.01% carbon or vice versa up to maximum manganese content
of 1.60% and maximum carbon of 0.22% for grades 50B and 50C.
D :The yield radio (max.) for all thickness of materials under grades A992 is 85%
E : For grades 50 steel of thickness 20mmand under , the tensile strength shall be a
minimum of 485 N/mm2.
F : A maximum of manganese of 1.50% is permissible , with an associated reduction
of the carbon maximum of 0.03%
G For the h section, when the t1 s 9mm or less, the upper limit of the yield point or
: proof stress shall not be applied.
H :For the H section , when the t1 is 9mm or less, the upper limit of the yield radio
shall be 85%
- Material under TIS compulsory standard are for domestic use only ,
while materials under other standards are for exportation.
