What is S550Q steel?
S550Q steel plate is a hydroelectric steel plate. It is a low-alloy high-strength steel plate and is a German standard steel plate. It has the characteristics of high yield and many strengthening alloy elements. When the S550Q steel plate is required to have thickness performance, you can also add a symbol representing the thickness direction, that is, the Z-direction performance level after the grade specified above, such as S550Q-Z15, S550Q-Z25, S550Q-Z35. S550Q steel plate composition(%) C:<=0.22, Si:<=0.86, Si:<=1.80, P:<=0.030 S:<=0.017, N:<=0.0060, Cu:<=0.55, Mo:<=0.74, Cr:< =1.60, V:<=0.14, Nb:<=0.07, Ti:<=0.07, B:<=0.0060, Ni:<=2.10 What are the mechanical properties of S550Q plates? Tensile strength Rm: 640-820MPa; Yield strength: 550 MPa; The elongation of copy after fracture is 16% S550Q steel plates delivery status S550Q plate is delivered in the quenched and tempered tempered state. It can also be attached to the requi...
