52100 tubing is a sort of hot-rolled or cold-rolled (cold-drawn) seamless steel tube.
There are strict requirements for bearing tube, particularly the uniformaity of chemical composition, non-metallic inclusion content and distribution of carbides.It can supply for producing kinds of bearing ferules, rollers and steel balls applied in combustion engine, electric motor car, automobile, tractor, lathe, rolling machine,drilling machines.
The following table outlines the relevant international standards and their corresponding equivalent grades for 52100 steel.
| Country | Standard | Equivalent Grades |
| International | ISO 4957 | 1.2067 |
| China | GB/T 1299 | GCr15 |
| USA | AMS 6440\ASTM A295\AMS 6444 \ASTM A29/A29M | 52100 |
| Europe | EN 10132 | 102Cr6 |
| Germany | DIN 17230 | 100Cr6 |
| Japan | JIS G 4805 | SUJ2 |
The Chemical Composition of 52100 Steel
| Element | Composition |
| Carbon (C) | 0.98 – 1.1 % |
| Chromium (Cr) | 1.3 – 1.6 % |
| Iron (Fe) | 96.5 – 97.32 % |
| Manganese (Mn) | 0.25 – 0.45 % |
| Phosphorus (P) | ≤ 0.025 % |

≤ 0.025 % |
Advantages of 52100 Tool Steel
High Wear Resistance: Ideal for high-load and rolling contact applications like bearings.
Good Toughness: Excellent impact resistance under stress.
Superior Hardenability: Deep hardening capability for enhanced strength.
High Edge Retention: Maintains sharpness, making it suitable for cutting tools.
52100 tubing is great for knives, offering high edge retention, toughness, and wear resistance. It's often used in high-end custom knives, though it can be harder to sharpen due to its high hardness (58-62 HRC).
