BS700MCK2 hot rolled coils

BS700MCK2 is one of a series of high-strength steel, China special steel limited, engineering machinery series of high-strength, ultra high strength structural steel. China special steel limited in 2000, first in China to the successful development of a new class of hot-rolled products, grades are mostly used at the beginning of BS, as the first generation of high-strength steel and BS700MC have been widely used in engineering machinery, container and other industries.

BS700MCK2 steel Chemical Composition :

Grade	C	Si	Mn	P	S	Alt	B
BS700MCK2	≤0.12	≤0.60	≤2.10	≤0.025	≤0.010	≥0.015	≤0.005

BS700MCK2 steel Mechanical Properties :

Grade	Thickness (mm)	Yield Strength Re(MPa)	tensile strength Rm(MPa)	Elongation A5（%）	Shock Value IE (J)
BS700MCK2	3-8	700-860	780-920	15-21	40-100
BS700MCK2	(8)-12	685-820	790-900	15-21	60-150

BS700MCK2 Delivery status: BS series adopt high-strength steel-rolled (TMCP) delivery.

Good Weldability --- carbon equivalent(Ceq) and weld crack sensitivity index(Pcm)

Grade	Performance carbon content C（%）	Performance carbon content Ceq	Welding sensitivity index performance Pcm
BS700MCK2	≤0.08	≤0.47	≤0.21

Ceq = C + Mn/6 (Cu + Ni)/15 + (Cr + Mo + V)/5
Pcm =C + Si/30 + (Mn + Cu + Cr)/20 + Ni/60 + Mo/15 + V/10 + 5B

The number of samples required for each batch of steel sheet and strip the test items, sampling methods, test methods shall be in accordance with Table 1

No.	Pilot projects	Number of tests，A	Sampling methods	Test method
1	Chemical analysis	Each furnace	GB/T20066	GB/T223 or GB/T4335
2	Stretching test	1	GB/T2975	GB/T228
3	Bending test	1	GB/T2975	GB/T232

BS700MCK2 steels plate/sheet are featured :
1 . Good formability. All grades of BS steel can be cold formed.
2 . Excellent welding performance. The steels have low welding crack sensitivity and the properties of welding joint are good.
3 . Good toughness at low temperature.
