BS550MCK4 steel,BS550MCK4 steel sheet/plate,BS550MCK4 steel supplier

BS550MCK4 hot rolling carbon low-alloy high strength steel design by reducing the carbon equivalent of the steel and welding crack sensitivity index, and use of advanced smelting equipment and technology to strengthen the collection of micro-alloying technology, good weldability.

BS550MCK4 steels 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.

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

BS550MCK4 hot rolling carbon low-alloy high strength steel design by reducing the carbon equivalent of the steel and welding crack sensitivity index, and use of advanced smelting equipment and technology to strengthen the collection of micro-alloying technology, good weldability.

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
BS550MCK4	≤0.08	≤0.49	≤0.22

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
