Question
Dear sir please tell me about the material BSK 4. what is the full name of this material and what are the properties also of this material BSK 46?

Answer
Dear Ashutosh,
BSK- BIG STEEL KEG (Tank type geometry used in auto component; There is no BSK-4 rather BSK-46.
(BSK 46)- can be produced by controlled cooling after hot rolling, has composition as under:
C          Mn          Si          S          P
0.12 max      0.8 1.4     0.25 max      0.01- 0.025          0.03 max
Nb:0. 08 max          Al: 0. 02 min          N: 80 PPM max       Cu:0.2 max
Mo+ Ni:0.4 max         Cr :- 0.2 max
Carbon Equivalent (CE):- 0.41 Max WHERE C.E. = (C+(Mn/6)+((Cr+Mo+V)/5)+((Cu+Ni)/15))
Trace elements other than specified should not exceed 0.2% in total by weight
Mech Prop:
UTS(Mpa)   500MPa  YS- 640 Mpa) ,% E 21min Bend
This is equivalent to IS: 5986 which is Hot rolled HSLA(High Strength Low Alloy Steel)
Did I pass in this test? you can discuss on 08800361391.
