If you’re intrigued by this question, then you’ve come to the right place. Today, we’ll delve deep into the mysterious world of 303 stainless steel, unveiling the 303 स्टेनलेस स्टीलची रचना आणि गुणधर्म.

303 स्टेनलेस स्टीलची रचना

303 स्टेनलेस स्टीलची रासायनिक रचना खालीलप्रमाणे आहे:

1. Carbon (C): Max 0.15%
2. Silicon (Si): Max 1.00%
3. Manganese (Mn): Max 2.00%
4. Phosphorus (P): Max 0.20%
5. Sulfur (S): Min 0.15%, Max 0.35%
6. Chromium (Cr): Min 17.00%, Max 19.00%
7. Nickel (Ni): Min 8.00%, Max 10.00%

In addition to these elements, 303 stainless steel may also contain trace amounts of copper (Cu), nitrogen (N), iron (Fe), and other elements. Adding sulfur to the composition gives 303 stainless steel excellent machinability, but it also reduces its corrosion resistance in some environments.
