1.2. The ovality of hot rolled bars should not exceed the diameter tolerance. The curvature of the bars should not exceed 6 mm per 1 running meter. m.

1.3. The length of the rods must be a multiple of the size of the workpiece part (the multiplicity is negotiated in the order), but not less than 500 mm.

2. TECHNICAL REQUIREMENTS

2.1. The chemical composition of the alloys must meet the requirements of table. 2.

2.2. Bars are supplied thermally untreated.

2.3. Mechanical properties determined on heat-treated control samples must meet the requirements of table. 3.

2.4. A conclusion on the long-term strength of a batch of bars is given after the test time specified for each grade of alloy. The supplier plant continues testing one of the samples until destruction: for vacuum arc metal from every fifth heat, for induction metal from every 10th heat.

2.5. The hardness of the metal, determined on control samples, heat-treated according to the modes specified in table. 3, must meet the requirements of table. 4.

TU 14−1-223−72

2.6. On the surface of the bars, there should be no captivity, cracks, flaws, sunsets, shells and slag inclusions.

The surface quality of the turned rods must meet the agreed standards.

On the surface of hot-rolled bars, local defects must be removed by gently scraping. The depth of cleaning of defects should not bring the rods beyond the minus deviation. Without stripping, individual small risks, dents and ripples are allowed within half the tolerance, counting from the face value.

2.7. The macrostructure of steel should not have traces of a shrinkage cavity, bubbles, cracks, fistulas, slag inclusions and voids visible without the use of magnifying devices.

The macrostructure of rods of all alloys provided for by these specifications and tested on heat treated macrotemplates must meet the requirements of the attached macrostructure scale.

Considered unacceptable: for vacuum-arc metal photos 15, 16, 17, 18, 21a, 21b, 22, 24, 25, 28a, 28b, 29, 30, 31, 32, 33, 34; for vacuum induction — photos 15, 16, 17, 18, 24, 25, 29, 30, 31, 32, 33, 34.

2.8. Fractures of thermally treated samples must meet the requirements of the fracture scale:

by the type of fractures — vacuum arc metal — 1−2 points, vacuum induction metal — 1−3 points and
by bundle — 1 point.

Note.
1. Defects subject to cleaning in accordance with clause 20 are not taken into account.

2. The consumer is given the right to reject, at the expense of the supplier, workpieces that have delamination and

Sheet 4
TU 14−1-223−72

other discontinuities identified by ultrasonic testing that do not fit into the norms on the scale of the macrostructure and the scale of fractures. In this case, the consumer plant, at the request of the supplier, is obliged to cut the workpieces selected by the supplier plant in an amount of at least 5 pieces from the submitted batch to confirm the presence of defects detected by the ultrasonic inspection by control of the macrostructure.

2.9. Regardless of the results of the inspection of bars, the consumer plant is given the right to reject finished parts at the expense of the supplier if defects of metallurgical origin are found on them after pickling — cracks, slag inclusions, hair lines and discontinuities visible to the naked eye.

3. RULES OF ACCEPTANCE AND TEST METHODS

3.1. Bars are presented for acceptance in batches from the same heat and diameter of the same size. The batch weight must be at least 150 kg. Delivery of lots of smaller weight is made with the consent of the consumer.

Note. Vacuum-arc melting is completed from no more than 10 ingots melted in a mold of the same cross-section, with an identical electric mode from the electrodes of the same initial melting.

3.2. If necessary, a control chemical analysis of any bar from those presented in the batch is carried out.

3.3. The dimensions and surface condition of all rods are monitored individually.

3.4. The control of mechanical properties is carried out in the finished grade on 2 samples for each type of test, taken from different

Sheet 5
TU 14−1-223−72

batch rods. Control samples are cut along the fiber from the center (along the axis) of rods with a diameter of up to 32 mm, inclusively and from the middle of the radius of rods with a diameter of more than 32 mm.

3.5. The control of the macrostructure and fracture is carried out on two samples, heat treated according to the regime provided in table. 3.

Samples are cut from two bars of each batch-melt for each type of tests, and samples for fracture control are taken in the transverse direction of the fiber (longitudinal fracture), and for control of the macrostructure — in the longitudinal direction of the fiber.

3.6. Long-term strength tests at high temperatures are performed in accordance with GOST 10145−62 on samples with a diameter of 5 mm, short-term tests — in accordance with GOST 9651−61 .

3.7. If the results of any test are unsatisfactory, a repeated test is carried out for this type of control on a double number of samples taken from the same rods. In case of unsatisfactory results of repeated testing of at least one sample, the melting batch is rejected.

The supplier plant is given the right to present the melt again after 100% control of the bars according to the indicator for which unsatisfactory results were obtained.

Note. Repeated and arbitration tests for determining long-term strength are performed on 2 samples according to the modes provided for in Table. 3.

4. MARKING, PACKAGING AND DOCUMENTATION

4.1. All bars must be stamped with the name of the supplying plant, alloy grade, heat number. Bars with a diameter of less than 30 mm are allowed to be branded with the conventional heat number with its decoding in the certificate.

Sheet 6
TU 14−1-223−72

The metal of vacuum-arc remelting should be branded additionally with the letters «VD», vacuum-induction — «VI».

4.2. The certificate establishing the compliance of this batch with the requirements of these technical specifications is signed by the quality control department of the supplying plant and the representative of the technical acceptance of the MAP.

Note. The certificate also includes the data of the primary tests, if the batch is recognized as suitable according to the results of the secondary test.
