Stable Performance Gb 40cr Pipe Annealing And Normalizing Process - China

1 - gb 40cr pipe pre-treatment preparation

material inspection: ensure the gb 40cr pipe meets the required chemical composition and quality standards.

surface cleaning: remove any rust, oil, or impurities from the surface to ensure uniform heating.

2 - gb 40cr pipe annealing

purpose: to soften the steel, improve machinability, and eliminate internal stresses.

process:

heat the steel plate to 820-840°c.

hold at this temperature for 1-2 hours (depending on thickness).

slowly cool in the furnace to 500°c, then air cool.

optimization tip: control the cooling rate to prevent excessive hardness or brittleness.

3 - gb 40cr pipe normalizing

purpose: to refine the grain structure and improve mechanical properties.

process:

heat the steel plate to 850-870°c.

hold for 1-2 hours.

air cool to room temperature.

optimization tip: ensure uniform heating to avoid uneven grain structure.
