GOST TP321H Heat Treatments
- For cold-formed pipes: ≥ 1100°C, quenching in water or accelerated cooling by other means
For hot-formed pipes: ≥ 1050°C, quenching in water or accelerated cooling by other means;
Heat treatment at temperatures above 1065°C may impair their resistance to intercrystalline corrosion. - Seamless and welded cold formed pipes: Heating at minimum 1100°C, quenching in water or accelerated cooling by other means.
Seamless and welded hot formed pipes: Heating at minimum 1050°C, quenching in water or accelerated cooling by other means.
