Product Description

5CrNi4Mo 1.2767 6F7 Cold Drawn Hot Work Tool Steel Tubes

5crni4mo 1.2767 6f7 Cold Drawn Hot Work Tool Steel Tubes

1: DIN   1.2767  steel introduction

     DIN 1.2767 is a higher carbon version of the standard 4.25% nickel oil hardening steel. It is a good quality tool steel that  achieves high impact and compressive strength and is suitable for applications demanding extra wear resistance. With its characteristics of good full harden-ability, good polishability and excellent toughness this cold work tool steel specification is widely used for plastic mould applications.

Application   DIN 1.2767 tool steel are suitable for forging tools, dies of all sort, shapes and sizes, hot forging and pressing tools for steel and metal. Moulds, bushings, piercers, plastic moulds, cutlery dies, shear blades for heavy gauge material, cutting tools, drawing jaws and highly stressed coining tools, etc..

6: Heat Treatment
Forging
     Heat the steel slowly and uniformly to 1050°C. Re heat as necessary and avoid working below 850°C After forging cool slowly in furnace or thermoinsulating material.
Annealing
     Heat uniformly to 630-650°C. Soak well and cool slowly in the furnace to approximately 600°C then cool in air.
Stress Relieving
     When dies produced in 1.2767 tool steel are heavily machined, stabilizing is recommended just before finish machining in order to relieve machining strains. Heat to approximately 650°C. Soak well and allow to cool in air.
Hardening
     Pre heat the tool slowly and uniformly to 650-700°C and thoroughly soak. Continue heating to the final hardening temperature of 840-870°C and allow the component to be heated through. Quench the component in oil or cool in air.
Temper i ng
     Slowly heat the 1.2767 tool uniformly and thoroughly at the selected tempering temperatures and hold at heat for one hour per 25mm of total thickness but for a minimum of two hours. Cool in air. 1.2767 tool steel can be hardened by vacuum furnace, gas quench process.
     Temperature [°C]   100   200   300   400   500   600
     Hardness [HRc]   56   54   50   46   42   38
Heat   Treat ment
     Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each 1.2767 steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of tool steels.
Final Grinding
     Select the correct grade of wheel in consultation with the grinding wheel manufacturer. Ensure the grinding wheel is in good condition by means of a suitable dressing tool. Wet grinding is a preferable option using a copious supply of coolant. If dry grinding is resorted to then use a very soft wheel.

 

 

7: Delivery condition
     For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
     For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.

     For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
