In the B2B sector, the 1.4112 8Cr17 AUS8 SUS440B Stainless Steel is necessary to manufacture components used in high-performing situations requiring long-lasting performance. A customized heat treatment procedure is necessary to maximize the potential of these steels.
Heat treatment entails heating and cooling steel under regulated conditions to produce qualities like greater hardness, higher wear resistance, and improved corrosion resistance.
Austenitizing |
Quenching |
Tempering |
| The steel is heated in this manner to a temperature of roughly 1000–1100°C. At this point, the steel changes into austenite, a high-temperature stage that facilitates the uniform dissolution of carbon and other alloying components. This guarantees a more robust product with reliable performance for cutting tool manufacturing companies. | The steel is quickly cooled, usually in water or oil, after austenitizing. This rapid cooling process changes the austenite into the tougher and more brittle martensite. Quenching is essential for businesses that need high hardness, such as toolmakers or knife manufacturers. As a result, the product may endure more severe wear and retain its sharpness for longer. | The steel is reheated to a lower temperature and held there for a while to apply tempering, which lessens the brittleness that is introduced during quenching. By taking this process, the steel can retain its hardness while regaining part of its toughness. When a balance between toughness and hardness is required, like in industrial machinery or automobile parts, tempering makes sure that the finished product is resilient enough to withstand wear and tear while preventing cracking or breaking under stress.

8Cr17 stainless steel has established itself as a dependable option when it comes to choosing the appropriate material for challenging industrial applications. Knowing the mechanical characteristics of 8Cr17 stainless steel will assist you in making wise decisions for your projects if your company is searching for high-quality materials.
The 8Cr17 stainless steel composition is 0.17% carbon, 12–14% chromium, and trace quantities of silicon, nickel, and manganese. Excellent corrosion resistance is a result of its high chromium content, which is crucial in settings subjected to humidity, chemicals, and severe weather.
The remarkable strength of 8Cr17 stainless steel is one of its most notable qualities. It provides strong performance for applications that are demanding with a tensile strength between 500 and 900 MPa. For parts that are subjected to high amounts of mechanical stress, this makes it a great option.
The hardness of 8Cr17 stainless steel might be a crucial factor for companies operating in the industrial sector. After heat treatment, the steel usually reaches a hardness of 55–58 HRC, guaranteeing resistance to wear and tear in components such as cutting tools, surgical instruments, and automobile parts.
Compared to other high-carbon steels, 8Cr17 is less likely to break under stress due to its moderate ductility, despite its reputation for hardness. It is crucial to remember that, when it comes to impact resistance at low temperatures, it is not as effective as austenitic stainless steels.
The moderate toughness of 8Cr17 guarantees that tools can withstand cracks and fractures while in use, which is crucial in industries like cutting tools and precision components.
The corrosion resistance, hardness, and edge retention balance make SUS440 stainless steel a highly valued material. Its unique qualities, however, distinguish it from more conventional tool steels such as D2, M2, and 1095, particularly in a variety of industrial applications.
In the marine industry, all tools and instruments are required to be resistant to saltwater. The SUS440 stainless steel properties make it ideal for the production of tools used in marine applications. This stainless steel is used for the production of propeller shafts and bearings.
It can also be used for diving and fishing equipment. One might ask why not use the 1095 stainless steel for this application; however, the 1095 requires frequent maintenance to avoid degradation, which is why the 8Cr17 is preferred.
Components like precision instruments and aircraft fasteners are usually manufactured from 8Cr17 stainless steel because of their corrosion resistance, ensuring reliability and durability. In aerospace applications, components are usually exposed to chemicals and high humidity, so most manufacturers prefer the 8Cr17 stainless steel for such applications rather than the M2 steel.
