DIN 2.4819 Flanges Hot Forming


Hastelloy C276 should be hot-formed in a temperature range of 950 to 1,200 °C (1,742 to 2,192 °F) with subsequent rapid cooling in water or in air. Heat treatment after hot-working is recommended in order to achieve optimal corrosion behavior. For heating up, workpieces should be placed in a furnace that is already heated up to the target value.


ASTM B564 N10276 Forged Flange Cold Forming


The workpieces should be in the annealed condition for cold working. Hastelloy C276 has significantly higher cold forming properties than the widely used austenitic stainless steels. This must be taken into account during design and selection of forming tools and equipment and during the planning of forming processes. Intermediate annealing is necessary for major cold-working treatment. When cold forming of > 15 %, final solution annealing must be conducted.


ASTM B564 N10276 Hastelloy Flanges Heat Treatment


Solution annealing should take place at temperatures of between 1,100 and 1,160 °C (2,012 and 2,120 °F).

  • For thicknesses d < 10 mm (0.4 in), the retention time is t = d ∙ 3 min/mm
  • For thicknesses d = 10 to 20 mm (0.4-0.8 in), the retention time is t = 30 min + (d – 10 mm) ∙ 2 min/mm
  • For thicknesses of d = 20 mm (0.8 in), the retention time is t = 50 min + (d – 20 mm) ∙ 1 min/mm
