Welded assemblies and blanks for pipeline valves according to ST CKBA 016-2005. Aging at 850-900 °C (with dwell time of 10 hours) + water hardening at 1080-1100 °C (with dwell time 1.0-1.5 h, 1.5-2.5 h for workpieces 90-150 mm), aging at 690-710 °C (at 10-50 h) + air cooling, air cooling (for CrN60M grade a single aging at 700 °C (at 50 h) is permissible). (CrN60M grade can be aged once at 700 °C (with exposure time of 50 hours), cooling in the air). Shape, dimensions, steel grade are regulated by the following requirements:

GOST 8560-78 - hexagonal calibrated;

GOST 4405-75 - hot-rolled and forged strip;

GOST 103-76 - hot-rolled flat steel;

GOST 2879-88 - hot-rolled hexahedral;

OST 14-2-205-87, GOST 2591-88 - hot-rolled square;

GOST 1133-71 - forged square and round;

GOST 7417-75 - round calibrated.

GOST 14 955-77 - with special surface finish;

GOST 2590-88 - hot-rolled round;

GOST 8559-75 - calibrated square;

Weldability:

Designation Description
Limited weldable - Preheating to 100-120°C with subsequent heat treatment is required
no restrictions - No need for preheating and final heat treatment
Difficult to weld - need preheating to 200-300 ° C with the final heat treatment
