If there is disagreement in the assessment of the chemical composition analysis carried out by chemical method.

8.3 Control dimensions

8.3.1 Measurement of the plate thickness performed at each selected 7.3 plate at a minimum distance of 115 mm from the vertex of the angle and not less than 25 mm from the edges of the plates with a Vernier caliper according to GOST 166.

8.3.2 the Width and length of plates measure measuring tape according to GOST 7502.

8.4 the Flatness of the plates determine the maximum deflection between the surface of the plate placed on a flat surface, and is attached to the plate metre ruler according to GOST 8026 in any direction by using a measuring ruler according to GOST 427.

8.5 Control of the edges and trimmed ends to the absence of fibre bundles is carried out visually, without the use of magnifying devices.

8.6 Inspection of surface plates is carried out without the use of magnifying devices.

The depth of defects measured by profilometer according to GOST 19300 or flat (special) depth gauge according to the normative document.

8.7 Selection of samples for mechanical testing is carried out according to GOST 24047.

Tensile tests carried out according to GOST 1497.

For tensile testing take one sample from each test plate.

Samples cut from plates across the direction of rolling must be calculated from the initial length or , as the specimens cut perpendicular to the plane of the plate, the initial estimated length .

Samples for tensile tests for plates all alloys with a thickness up to 80 mm cut from the middle layers of the slab in the direction transverse to rolling, and plates of a thickness of from 40 to 80 mm of alloys D1, D16, D19, AK4−1, V95, also in the direction perpendicular to the plane of the plate.

Samples for tensile testing of plates with a thickness of 25 to 50 mm of alloy grade V95 cut out the middle layers of the heat-treated workpieces in the direction transverse to rolling, and plates of a thickness of from 40 to 50 mm in the direction perpendicular to the plane of the plate. Blank dimensions must be at least 50 to 250 N mm, where N is the thickness of the plate.

Verification of the mechanical properties of plates of alloy grade 1915 manufacturer conducts 2−4 day natural aging, and the consumer is 30−35 days.

9 Transportation and storage

9.1 Transportation plates — according to GOST 9.510.

9.2 When stored plates must be protected from mechanical damage, moisture and active chemical substances.

Under specified conditions of consumer properties of plates in storage do not change.
