Description

АЦ28ХГН3ФТ steel is used: for bars in high precision, used for the manufacture of sucker rods (to transfer the reciprocating or rotational motion from ground drive to the downhole oil pump); shaft hydroprotection (diameter 25, 30 and 35 mm); the shafts of submersible motors.

Note

Steel high strength high workability.

Fe is the basis.
According to TU 14-1-4398-88, 0.02-0.03% calcium is calculated for microalloying to steel (0.001-0.020% for obtaining in finished metal) and 0.004-0.006% for barium (for the production of 0.001- 0.005%); chemical or other methods of analysis of calcium and barium do not determine. In the finished rolled products deviations from the norms of chemical composition are allowed in accordance with GOST 4543.

Macrostructure and contamination In the macrostructure of bars on the other 14-1-4398-88 should not be the remnants of a shrinkage pipe, podnasadochnogo looseness, bubbles, cracks,placenow. Obesplozhennym layer on the surface And bars are not allowed.
Features of heat treatment Bars on the other 14-1-4398-88 put in normalized (air cooling with temperature end of rolling) and the released condition with surface cold deformation during dressing-grinding. Depending on the hardness of the bars are subdivided into 2 groups (see Table mechanical properties).
