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
