What is L6 bainite?
What is L6 bainite?
L6 is a nickel-rich steel with great impact resistance that was originally developed for saw blades – when carefully heat treated into its Bainite phase this steel becomes exceptionally tough and resistant to damage.
How strong is L6 steel?
The L6 tool steels contain 0.70% carbon with a quenched hardness of about 64 HRC. The alloying elements in these tools steels are chromium and molybdenum, and 1.50% nickel to increase toughness. These tool steels can maintain hardness above 60 HRC for sections of 75 mm (3 in.)
Is L6 steel any good?
L6 is a low alloy oil hardening tool steel. The high Nickel content makes it extremely tough. The edge holding isn’t as good as other steels but it still makes a good knife. It is an excellent choice for big choppers and swords.
What is bainite made of?
A fine non-lamellar structure, bainite commonly consists of cementite and dislocation-rich ferrite. The large density of dislocations in the ferrite present in bainite, and the fine size of the bainite platelets, makes this ferrite harder than it normally would be.
How does Bainite form in a steel alloy?
Bainite in Steels Materials Science & Metallurgy Part II Course C9, Alloys, H. K. D. H. Bhadeshia Bainite in Steels Bainite forms by the decomposition of austenite at a temperature which is above M Sbut below that at which fine pearlite forms. All bainite forms below the T 0temperature.
What is the temperature at which bainite forms?
Bainite is an acicular microstructure (not a phase) that forms in steels at temperatures from approximately 250-550°C (depending on alloy content).
What’s the difference between Lower bainite and upper bainite?
A further distinction is often made between so-called lower-bainite, which forms at temperatures closer to the martensite start temperature, and upper-bainite which forms at higher temperatures. This distinction arises from the diffusion rates of carbon at the temperature at which the bainite is forming.
What makes a bainite a non lamellar structure?
A fine non-lamellar structure, bainite commonly consists of cementite and dislocation-rich ferrite. The high concentration of dislocations in the ferrite present in bainite makes this ferrite harder than it normally would be.The temperature range for transformation to bainite (250-550°C) is between those for pearlite and martensite.
