Why is austenitic stainless steel commonly used in engineering design?
It should be considered comprehensively in terms of strength and weldability
Austenitic structures generally have moderate strength and high malleability
I. This statement is incorrect. It can be said that austenitic stainless steel is commonly used in the selection of materials for chemical processing equipment. II. Apart from its relatively good corrosion resistance, austenitic stainless steel has few other advantages. III. However, it is commonly used for non-load-bearing exteriors in decoration projects.
As a supplementary point, austenitic stainless steels exhibit excellent mechanical properties at low temperatures, and are commonly used as materials for low-temperature pipelines and valves.
1. Austenitic stainless steel is used in harsh environments due to its strong corrosion resistance. 2. It is employed in high-temperature or low-temperature environments owing to its good high-temperature strength and relatively excellent low-temperature impact resistance. 3. From the perspective of its structural composition, austenitic stainless steel maintains an austenitic structure at all conditions, as the name implies; there is no structural transformation, resulting in relatively stable properties.
