S650MC hot rolled high strength structural steel plate

Description

The high-strength structural steel at 650 MPa

S650MC is a hot-rolled structural steel made for cold forming, with a minimum yield strength of 650 MPa for stronger and lighter structures.

S650MC meets or exceeds the requirements in EN 10149-2.

Typical applications include a wide range of components and parts, such as demanding load-bearing structures. S650MC comes in coils, slit coils or cut-to-length sheets.

Dimension Range

S650MC steel is available in thicknesses of 2.00-10.00 mm and widths up to 1600 mm as coils, slit coils or cut to length sheets in lengths up to 16 meters.

Mechanical Properties

The mechanical properties are tested in the longitudinal direction.

(1) If ReH is not applicable then Rp 0,2 is used.

(2) On thicknesses >8 mm the minimum yield strength may be 20MPa lower.

(3) A80 value applies for thicknesses < 3.00 mm.

(4) A5 value applies for sheet thickness t ≥ 3mm.

(5) For both longitudinal and transverse direction.

Impact Properties

Impact testing according to EN ISO 148-1 is performed on thicknesses ≥ 6mm. The specified minimum value corresponds to a full-size specimen.

Chemical Composition (ladle analysis)

(1) If the material is to be hot-dip galvanized according to category A or category B in EN 10149-2 this must be specified at the time of order. Other galvanizing classes with higher Si-content are available after agreement.

(2) Sum of Nb, V and Ti = max 0.22%

The steel is grain refined.

Thickness

Tolerances according to EN 10051.

Length and Width

Width and length tolerances according to EN 10051. Length tolerances only apply for cut to length sheets.

Shape

Delivery Conditions

Thermomechanically Rolled. S650MC steel is available in as rolled or pickled surface condition with mill or cut edge.

Fabrication and Other Recommendations

Welding, bending and machining

S650MC steel has good welding, cold forming and cutting performance.

S650MC steel is a cold forming steel not suited for heat treatments at temperatures above 580 °C since the material then may lose its guaranteed properties.

Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the product.

Specification
