For nuclear power plants

These technical conditions apply to ingots for the production of tubular blanks and sheet metal products made of corrosion-resistant steel grades 04Kh14TZR1F (ChS82) and 04Kh14T5R2F (ChS82M).

Example of a symbol:

Ingot with a diameter of 460 mm, length of 1625 mm made of steel grade 04Х14Т5Р2Ф (ЧС82М):

Ingot 460x1625-04X14T5R2F (ЧС82M) TU 14-1-5604-2010.

The list of regulatory documents (RD) referenced in the text of these technical conditions is given in Appendix A. Codes for steel grades and ingots are given in Appendix B.

At the customer's request, specified in the order, the ingots must meet the "Terms of Delivery 01-1874-62", Special Conditions for the Delivery of Equipment, Instruments, Materials and Products for Nuclear Power Facilities.

The production of products according to these technical specifications is carried out only upon orders from TVEL-INVEST-TECHNOLOGY CJSC.

1 Assortment

1.1 Ingots are produced in the dimensions specified in Table 1.

Table 1

2 Technical requirements

2.1 The chemical composition of steel must comply with the standards given in Table 2.

Table 2

2.1.1 In finished metal products, the ratio of titanium to boron should be

2.1.2 Mass fraction of residual elements - according to GOST 5632.

2.1.3 The average size of boron-containing phases in steel should be no more than 50 µm.

The results of the control are optional and are made in agreement with TVEL-INVEST-TECHNOLOGY JSC.

2.2 Ingots are supplied in a mechanically processed condition. The surface of the ingots must be free of films, folds, crusts, cavities, cracks, and foreign non-metallic inclusions. Local defects may be removed from the surface of the ingots by cutting or cleaning to a depth of no more than 10 mm with a gentle slope that ensures a cleaning depth to width ratio of at least 1:6. Diametrically located cutting or cleaning areas are not permitted.

Step-by-step mechanical processing is allowed (the difference in diameters along the length of the ingot is no more than 10 mm) with smooth cleaning of the transition areas with a cutter or abrasive

2.3 Ingots are supplied in annealed condition according to the manufacturer's regime.

2.4 The macrostructure of the ingots must not contain internal discontinuities of metallurgical origin, namely: cracks, shrinkage cavities, foreign metallic and non-metallic inclusions, the detection of which is carried out during ultrasonic testing of the ingots.

2.5 The ingots are subjected to 100% ultrasonic testing according to the manufacturer's method.

The layer of grease after ultrasonic testing must be removed by wiping with a rag.

3 Acceptance rules and testing methods

3.1 General rules for acceptance of ingots - in accordance with GOST 7566.

3.2 Ingots are presented for acceptance in batches consisting of ingots of the same size, the same heat treatment mode and the same initial melt, including those remelted under the same modes.

3.3 The absence of surface defects is checked in the delivery condition by inspecting all ingots without the use of magnifying devices; if necessary, control brightening or etching of the surface may be carried out.

3.4 Measurement of the mass fraction of boron in ingots is carried out using two independent methods: chemical and spectral.

3.5 Samples for chemical analysis are taken in accordance with GOST 7565, chemical analysis is carried out in accordance with GOST 12344 - GOST 12352, GOST 12354 - GOST 12357, GOST 12360, GOST 12364, GOST 18895, GOST 28473, or other methods that ensure the required accuracy of determination.

3.6 All ingots of a batch are subjected to ultrasonic testing according to the manufacturer's method. The following are considered defective:

- the presence of a defect, the amplitude of the echo signal of which is equal to or exceeds the echo signal from a flat-bottomed reflector with a diameter of 7 mm, with a conditional length of the defective section of 50 mm or more;

- the presence of a non-extended defect, the amplitude of the echo signal of which is equal to or exceeds the echo signal from a flat-bottomed reflector with a diameter of 10 mm.

A decrease in the amplitude of the bottom signal or its disappearance in areas whose total length does not exceed 10% of the ingot length (mainly the electrode fusion zone) is allowed.

4 Marking, packaging, transportation and storage

4.1 Marking, packaging, transportation and storage - according to GOST 7566.

4.2 Additional requirements:

4.2.1 Steel obtained by special methods is additionally designated by a dash at the end of the grade name with the corresponding letters.

4.2.2 Each ingot shall be marked with the melt number, ingot number, steel grade or its conventional designation. Marking is done by stamping. The stamp is applied to the ingot and outlined with bright paint. The stamp must be clear and preserved during transportation.
