52100- This steel is very similar to 5160 but it sacrifices some toughness for better edge holding ability and wear resistance. “. This site uses Akismet to reduce spam. They are both carbon steels the only difference is in Chromium (52100 has more chromium in it). AISI 52100 is a high carbon tool steel containing low quantities of manganese and chromium to improve hardening. It’s used for parts such as bearings, bushings, and punches. 52100 Corrosion Resistance: 52100 is poor in Chromium (Only 1.5%), which makes it corrosive and exposed to rust. Depends on how they're heat treated. Manufacturer: Various 52100 is an alloy steel that is commonly used in ball bearings. Alloy 52100 grade is primarily used for the manufacture of aircraft bearings and other highly stressed parts. It was really three screws to remove and I had access to the blade. Stropping the blade on leather… The blade is perfectly centered. “52100 Tool Steel Alloy 52100 is a high - carbon, chromium - bearing steel with excellent strength and fatigue properties. GCr15 vs 52100, 100Cr6 and SUJ2 are all bearing steel grades, they are similar in chemical composition and properties. “52100 Tool Steel AISI 52100 is a high carbon tool steel containing low quantities of manganese and chromium to improve hardening. AISI 52100, ball bearing steel. Certificates with a traceable lot number are available for these products. It’s better to take the blade out of the bath and envelop it with paper towels. Because of the low chromium levels in 52100 steel, it has very low corrosion resistance compared to other higher chromium tool steels. This material is used often for hunting knives. Stainless steel can still rust under the right conditions. 52100 Steel - This is high carbon tool steel. The following table and lists show 52100 datasheet and specification including chemical composition, mechanical properties and heat treatment, etc. Another famous carbon steel in the world of Knife Making, the 52100 Steel, while reading knives forums, I found out some users claim that 52100 is very good for knives, so I did some investigations, and yes, I ended up doing a 52100 Steel Review. AISI 52100 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling to reduce cold working or machining stress.

Because of the low chromium levels in 52100 steel, it has very low corrosion resistance compared to other higher chromium tool steels. As you can notice this is not really deep pitting. AISI 52100 Alloy Steel. The Hardness or Rockwell hardness is a maximum of 64-66 HRC. Equivalent grades steel number of 100Cr6 Bearing Steel Bars | 100Cr6 Round Bar | 100Cr6 Flat Bars: EU EN: EN31, 1.2067, 1.3505, 100Cr6, 102Cr6 USA AISI | SAE: 52100, G52986, J19965 Germany DIN,WNr: 1.3505, 100Cr6, 102Cr6 Japan JIS: SUJ2, SUJ4 France AFNOR: 100C6, 100Cr6, 100Cr6RR England BS: 2S135, 534A99, 535A99 Italy UNI: 100Cr6 Spain UNE: 100Cr6, F.1310 … Incidentally, it is also an excellent knife steel, with possibly the best performance out of many of the tool/carbon steels and reaches hardness of about RC 66, with typical knives usually in the high 50's. 52100 steel is high carbon steel equivalent to 1095 steel with little addition of chromium. For technical drawings and 3-D models, click on a part number. – NemoKnivesReview, The Spyderco Dog Tag sees a little action by JD, A star is born! Et voilà: fight rust ! According to Carolina Knife Company. Additionally, the blades have been parkerized to a black finish which will help minimize rust and glare. “52100 Tool Steel AISI 52100 is a high carbon tool steel containing low quantities of manganese and chromium to improve hardening. 52100 is the better steel if one can stand the corrosion resistance being low for those who demand the best sharpness. Of course yesterday I have put some vinegar to create my patina and some drops have been near the pivot… It was fast in rusting in that area without patina. Download certificates from ACTIVITY after your order ships. Due to its excellent hardness and wear resistance, it exhibits good fatigue life in rolling element bearings.
