5: Ultrasonic Test
EN10228-3 class III or Sep 1921-84 D/D
6：Steel making & Forging processing
1): Steel making process:
EF+LF+VD
EAF+LF+VD
EF+LF+VD+ESR
EAF+LF+VD+ESR
2): Forging processing:
Initial temperature: 1100-1150℃
Final temperature: 950℃
Cooling in the furnace or in the sand
7: Heat treatment
1): Annealed:
Heat 1.2605 steel to 820-840℃
Cooling in the furnace.
2): Quenching and tempering:
Heat 1.2605 steel to 1010-1030℃ in the salt bath furnace
Quench in the Oil
Temper steel at 540-560℃ in the furnace
Cooling in the air.
Above curve in figure is a rough guide to the tempering behaviour of steels.
8：Application
1.2605 Steel—High heat resistance, excellent thermal shock toughness, good wear resistance, and high-temperature hardness. Its applications are highly specialized, primarily serving hot-working die scenarios with extremely demanding temperature requirements. Below are the main application categories for 1.2605 steel:
1. High-Temperature Metal Die Casting and Extrusion Dies
Copper Alloy and Heavy Metal Alloy Die Casting: Brass and bronze faucets, valves, gears, connectors, etc.
Aluminum Alloy Die Casting: Engine blocks, cylinder heads, transmission housings, wheel hubs, etc.
Hot extrusion dies: For producing bars, tubes, and profiles from copper/copper alloys and aluminum/aluminum alloys
2. Other hot-work tooling applications
Hot stamping and hot forging dies: Punch and die components for forging high-alloy steels, titanium alloys, or other high-melting-point metals
Plastic molds: For processing highly corrosive plastics (e.g., PVC) or engineering plastics requiring high-temperature forming
