BG42 is a high performance stainless steel that is specifically designed for aerospace structural components and high performance bearings. BG42 stainless steel is widely used in tool manufacturing and tool manufacturing because of its excellent hardness and excellent corrosion resistance. Molybdenum in steel enhances the corrosion resistance provided by the high chromium content. In addition, the content of carbon, molybdenum and vanadium provides a total carbide volume of about 19%, which also makes excellent cutting edge retention and long life in the tool blade.

Practical Advantages of BG42 Stainless Steel
Stainless steel known as BG42 offers some of the finest characteristics of steel giving it wide acceptance in industrial and precision engineering applications including use in knitting and the Aerospace industry for the production of knives. This multi-purpose material has the following outstanding features:
The steel is harder and has better edge retention than the other types of steel, as it has a higher carbon content in the range of 1.10–1.20 % and a higher vanadium content in the range of 1.10–1.30%. As a result, it is a suitable substance for precision cutting instruments.
Holds higher geometry sharpness compared to a lot of other stainless steels.
Less frequent sharpening and hence recommended for professional tools and knives.
We get a detailed analysis of the chemical composition of each wheel, including a high chromium content of about 14.5%, as well as molybdenum of about 4%, which is why such wheels are said to be high and resistant to wear or corrosion.
It resists abrasion which very much helps in enhancing equipment life.
Resists MPH even in humid or wet places, or where the surroundings environment may be corrosive; ideal for maintaining the shape or cutting edge of tools that are in contact with moisture or in extreme conditions.
To maximize its performance, BG42 requires proper heat treatment. To ensure the best results, BG42 stainless steel requires precise heat treatment. For businesses in need of bulk purchases, Zeicin guarantees consistent quality and reliable supply of BG42 stainless steel. Here is an outline of the heat treatment process:
| Heat Treatment and Microstructure Specitions | Process | Temperature | Cooling Method |
| Heat Treatment Specifications | Annealing | 885~899℃ | Slow Cooling |
| Quenching | 222~538℃（for pressurized gas） | – | |
| Quench until black about 482℃（for oil） | then cool in still air to 66~51℃ | ||
| 538~593℃（for salt maintained） | then cool in still air to 66~51℃ | ||
| Tempering | 510~566℃ | Rapid Cooling | |
| Austenitizing ( High Heat ) | 1121℃( OR 1066~1080℃ for underhardening) | – | |
| Preheating | 816~843℃ | – | |
| Cryogenic Treatment | -73℃ | Cooling to -73℃，then air cool to ambient temperature |
Maintaining BG42 stainless steel is easy and cost-effective, making it a top choice for industries that require long-lasting materials. If you’re considering wholesale BG42 stainless steel for your business, our maintenance recommendations help maximize product longevity.
The mechanical properties of BG42 stainless steel are remarkable and make it the perfect material for industrial segments hence it may be used in the prop industry. Below are its key properties:
| Property | Value |
| Hardness | Exceptional hardness due to carbon (1.15%) and vanadium (1.2%) content. |
| Tensile Strength | High strength enabling resistance to extreme mechanical stress, thanks to fine grain structure and martensitic nature. |
| Edge Retention | Superior sharpness and long-lasting cutting edge due to fine grain structure and vanadium content. |
| Corrosion Resistance | Chromium and 4% molybdenum provide excellent protection against moisture, salt, and other corrosive environments. |
| Wear Resistance | Ideal for abrasive and high-friction applications, enhanced by molybdenum and vanadium, improving surface wear resistance. |
BG42 stainless steel excels in a variety of demanding applications:
As far as the materials of workpieces are concerned, BG42 Stainless Steel made by Zeicin is among the industries’ best material, where Chinese products are relatively at the same level as the Japanese, Europeans, and American ones. Regardless the question is related to material applied for production, manufacturing tolerance, or cost control, Zeicin guarantees high-quality product. Zeicin also offers BG42 stainless steel at competitive prices, making it an excellent choice for bulk purchase and wholesale options.
BG42 Stainless Steel has also been totally checked by our experts with other materials that have been tested and passed by the aviation industry ranging from American aircraft carrier. By adopting international quality standards with reasonable prices, customers prefer Zeicin, receiving the quality of the best international counterparts.
Traditionally, the carbon and vanadium contents of BG42 are high, its grain size is fine, and it is produced by state of the art powder metallurgy technique that gives the blade excellent edge holding capacity or in other words high wear resistance.
This type of material was invented by Latrobe Steel in California of USA, where the product was made by Powder Metallurgy for aerospace class.
In conditions which can be characterised as severe, the described advantages of BG42 EP rubber ensure its increased tensile strength, wear resistance as well as stability of its functional properties in abrasive and corrosive surroundings.
