1. **High Carbon Chromium Bearing Steel**
High carbon chromium bearing steel includes grades such as GCr15, GCr9, GCr6, and GCr15SiMn. These materials are commonly used to manufacture rolling elements for bearings operating under normal conditions. They account for over 85% of the steel used in rolling mill production due to their high hardness and wear resistance.
2. **Carburized Bearing Steel**
Carburized bearing steels include 08, 10, 25, 15Mn, G20CrMo, G20CrNiMo, G20CrNi2Mo, G20Cr2Ni4, G10CrNi3Mo, and G20Cr2Mn2Mo. These steels are ideal for applications requiring impact resistance and durability. Low-carbon steel balls are often used for cost-effective bearings, while alloy carburized steels are preferred for high-load applications like automotive and industrial rolling mill bearings.
3. **Stainless Bearing Steel**
Stainless bearing steels such as 9Cr18, 9Cr18Mo, 0Cr18Ni9, 1Cr18Ni9, 1Cr18Ni9Ti, 1Cr17Ni2, 1Cr13, 2Cr13, 3Cr13, and 4Cr13 are suitable for use in corrosive environments. They are typically used for bearing cages that require corrosion resistance and long service life.
**Special Tumbling Data**
1. **High-Temperature Bearing Steel**
High-temperature bearing steels like Cr4Mo4V (M50), W9Cr4V2Mo, Cr15Mo4V, W18Cr4V, and W6Mo5Cr4V2 are designed for high-temperature and high-speed applications. These materials are used in critical components of gas turbines and aero engines where thermal stability is essential.
2. **Medium Carbon Bearing Steel**
Medium carbon bearing steels such as GCr10, 40CrA, 65Mn, 50CrNiA, and 55SiMoV are used for rolling elements subjected to impact loads. For example, 55SiMoV is commonly used in the rolling elements of turbo drill bearings due to its excellent fatigue strength.
3. **Non-Magnetic Bearing Materials**
Non-magnetic bearing materials include G52, G60, 25Cr18Ni10W, Ocr40Ni55A13, QBe2.0, and NiCu28-2.5-1.5. These are used in specialized environments:
- **G52**: Used for non-magnetic high-temperature and high-pressure water bearing rollers.
- **G60**: Suitable for non-magnetic bearings in high-temperature, vacuum, and oxidizing environments.
- **25Cr18Ni10W**: Ideal for non-magnetic tumbler bearings.
- **Ocr40Ni55A13**: Used for non-magnetic tumbler bearings in harsh conditions.
- **QBe2.0**: Designed for non-magnetic low-temperature corrosion-resistant tumbler bearings.
- **NiCu28-2.5-1.5**: A non-magnetic, corrosion-resistant steel ball material.

Aluminum sliding doors are a practical and beautiful type of door, which usually consists of two parts: the door frame and the door flap. The door frame is fixed to the wall, while the door door can slide freely inside the door frame. According to different design needs, the sliding door can be single, double or multi-fan structure. Among them, the double sliding door is more common, which allows the two sides of the door to slide towards the middle or both sides at the same time to achieve a greater opening width. In addition to the selection of high-quality aluminum profiles, the glass material should also be selected with good light transmission and high-quality glass. It can be used in the living room, bedroom, bathroom, kitchen and other areas of the family residence. It can also be used in office environments and commercial places. In short, the sliding door occupies an important position in the field of modern architectural decoration with many advantages such as space saving, material diversity and flexible design.
