X30Cr13 stainless steel is widely used in the aerospace industry

　　X30Cr13 stainless steel has ultra-mirror machinability, which means it can achieve a very smooth surface, meeting the requirements of high-precision machining. In the annealed state, it also exhibits good machinability. Here is a more detailed description of the characteristics of X30Cr13 stainless steel:

　　X30Cr13 chemical composition:

　　Carbon C: 0.26~ 0.35

　　Silicon Si: ≤ 1.00

　　Mn: ≤ 1.50

　　Sulfur S: ≤ 0.030

　　Phosphorus P: ≤ 0.040

　　Chromium Cr: 12.00~ 14.00

　　X30Cr13 mechanical properties:

　　Tensile strength (MPa): quenching and tempering, ≥ 800~ 1000

　　Conditional yield strength of 0.2 (MPa): quenched and tempered, ≥ 600

　　Elongation δ 5: quenching and tempering, ≥ 10

　　Ultra-mirror processing performance: X30Cr13 stainless steel can achieve a very smooth, mirror-like surface after surface treatment. This makes it ideal for applications that require high-precision processing and appearance requirements, such as optical instruments, touchscreen technology, electronics, etc.

　　Good machinability in annealed state: When X30Cr13 stainless steel is in annealed state, it has good plasticity and machinability. This makes it easy to perform various machining operations, such as cutting, punching, bending, etc.
