Is Bohler K110 steel good?
Bohler K110 (D2) – Origin Austria K110 more commonly known as D2, is a high-carbon, high-chromium, semi-stainless tool steel. Due to its outstanding hardness, strength, wear and abrasion resistance, K110 has excellent characteristics for making extremely rugged blades and hand tools.
Is K110 steel good for knives?
K110 is a cold work tool steel from Austria. It is a dimensionally stable, high carbon, high-chromium (12%) steel. Particularly suitable for air hardening it also has good toughness. Due to its strength and durability, K110 has excellent characteristics for a blade.
What is Bohler K110?
Bohler K110 (AISI D2 / JIS SKD11, DIN 1.2379) is one of the main steels that I use for my kitchen knives. It’s classified as a hypereutectoid cold work tool steel that is typically used for blanking dies, slitting cutters, shear blades, forming dies, knurls, gages (plug and thread), punches, trimming dies, etc.
How do you heat treat D2 tool steel?
D2 should always be annealed after forging. Heat slowly to 1550°-1600°F, hold until entire mass is heated through, and cool slowly in the furnace (40°F per hour) to about 1000°F, after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
What is K390 steel?
K390 is German steel developed by Bohler for use in cold work applications as well as in parts subjected to abrasive wear at the time of processing plastics. It refers to a type of advanced tool steel that Bohler makes using its exclusive particle metallurgy process, also known as the MicroClean technology.
Is Elmax stainless?
Elmax is a 3rd generation powder stainless steel produced by Bohler-Uddeholm. It features high chromium, molybdenum, and vanadium content, which give it high corrosion and wear resistance.
Can D2 be hardened?
Hardening: D2 tool steel is extremely sensitive to overheating during hardening – do not overheat. Pre heat slowly to 750/780°C and soak. Continue heating to the final hardening temperature of 1000/1030°C and allow the component to equalise.
How much does D2 grow in heat treat?
Estimating Size Change During Heat Treat An Uddeholm data sheet shows that when D-2 tool steel, 3.15″ x 3.15″ x 3.15″, is austenitized at 1,870 degrees F for 30 minutes and quenched in a vacuum furnace with 2 bar nitrogen overpressure, it grows in one dimension while shrinking in the other two.
Can you harden D2 steel?
How good is K390?
What is k390 steel hardness? K390 hardness is 64-65 HRC, which gives it the tag of very hard steel. Though this might seem on the lower side than what you get with higher-end steels like Maxamet (67-68HRC), it still offers great wear resistance, which makes it suitable for making high-quality knives.
