Жоғары температура қолданбаларына арналған 6 ең жақсы баспайтын болаттар

When dealing with elevated temperatures, it is crucial to choose a stainless steel grade that can withstand the thermal stress, maintain its mechanical properties, and resist corrosion. In this article, we will introduce 6 of the жоғары температурада қолдануға арналған ең жақсы баспайтын болаттар.

Best Stainless Steels for High Temperature Applications – 1. 304 Stainless Steel

304 баспайтын болат, Сондай-ақ, белгілі 18/8 болат, кеңінен қолданылады аустенитті баспайтын болат grade. It has good corrosion resistance, high ductility, and excellent welding properties. Although 304 stainless steel has a maximum service temperature of around 800°F (427°C), it is often used in high-temperature applications due to its cost-effectivenesss and ease of processing.

Best Stainless Steels for High Temperature Applications – 2. 316 Stainless Steel

316 баспайтын болат is a more corrosion-resistant version of 304, with the addition of molybdenum. This addition improves its resistance to pitting and crevice corrosion, making it suitable for use in chloride-rich environments. 316 stainless steel can also withstand temperatures up to 1600°F (871°C) in intermittent service.

Best Stainless Steels for High Temperature Applications – 3. 310 Stainless Steel

310 баспайтын болат is a heat-resistant austenitic grade that is commonly used in high-temperature applications. It has a higher chromium and nickel content than 304 and 316, which gives it better oxidation resistance at temperatures up to 2100°F (1149°C). 310 stainless steel is often used in furnaces, heat exchangers, and other high-temperature equipment.

Best Stainless Steels for High Temperature Applications – 4. 321 Stainless Steel

321 баспайтын болат is similar to 304 but with the addition of titanium or columbium to stabilize the austenitic structure. This stabilization prevents the formation of harmful chromium carbides at high temperatures, maintaining the corrosion resistance of the steel. 321 stainless steel is suitable for use in temperatures up to 1600°F (871°C) and is often used in welding applications.

Best Stainless Steels for High Temperature Applications – 5. 347 Stainless Steel

347 баспайтын болат is another heat-resistant austenitic grade with a stabilization treatment similar to 321. It has a high chromium and nickel content, which gives it good oxidation resistance at temperatures up to 2000°F (1093°C). 347 stainless steel is often used in high-temperature applications that require excellent corrosion resistance and weldability.

Best Stainless Steels for High Temperature Applications – 6. 430 Stainless Steel

430 баспайтын болат is a ferritic stainless steel grade that has good corrosion resistance and is cost-effective. It has a lower nickel content compared to austenitic stainless steels, making it more resistant to thermal aging. 430 stainless steel can be used in temperatures up to 1500°F (816°C) but is less suitable for continuous high-temperature exposure due to its lower ductility and toughness.

қорытынды

In conclusion, the selection of the most suitable stainless steel grade for high-temperature applications depends on the specific requirements of the application, such as the maximum operating temperature, corrosion resistance, cost, and processing considerations. The 6 stainless steel grades introduced in this article offer a range of properties that cater to different high-temperature needs, from cost-effective general-purpose alloys to high-performance heat-resistant grades.
