Product Details

Chemical composition
Based on melting analysis, the following limit values (%) apply to each component

C	Si	Mn	P	S
≤0.20	≤0.70	≤1.80	≤0.025	≤0.010

Depending on the thickness, one or more of the following alloying elements are added:

Mo	Ni	Cu	Cr	V
≤0.50	≤0.80	≤0.30	≤1.50	≤0.08

The molten steel is treated with full sedation and fine grain processing.

Carbon equivalent reference value:

Steel plate thickness (mm)	10	25	40	80	120
CEV^a	0.45	0.49	0.56	0.63	0.67
CET^b	0.30	0.32	0.35	0.36	0.37

^aCEV=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15

^bCET=C+(Mn+Mo)/10+(Cr+Cu)/20+Ni/40

Delivery status
Controlled warm water quenching

Delivery condition mechanical properties

Brinell hardness at room temperature: 370-430 HBW
Transverse specimen tensile test at room temperature (20mm thick steel plate reference value)
Tensile strength: 1200 MPa (175 ksi) ³
Yield point: 800 MPa (116 ksi) ³
Elongation: 12% (Lo = 5.65 √So)
DILLIDUR, despite its high tensile properties, is not suitable for safety-focused applications, in which case, choose DILLIMAX, a high-strength steel plate.
