Although both 430 stainless steel shot and 304 stainless steel shot are stainless steel, they both contain carbon, manganese, phosphorus, sulfur and other elements, and both have certain corrosion resistance, formability, compatibility and strength and toughness.
But there are also differences in many aspects:
1. Corrosion resistance: 430 stainless steel shot contains 16.00-18.00% chromium and basically contains no nickel metal; 304 stainless steel contains more chromium and nickel metal, so the corrosion resistance of 430 stainless steel is not as good as that of 304 stainless steel.
2. Stability: 430 stainless steel shot is in ferrite form, and 304 stainless steel is in austenitic form, so 304 stainless steel shot is more stable than 430 stainless steel.
3. Toughness: 304 stainless steel shot has strong toughness, which is stronger than 430 stainless steel.
4. Thermal conductivity: The ferrite of 430 stainless steel has better thermal conductivity than the austenite of 304 stainless steel.
5. Mechanical properties: 430 stainless steel has the chemical element titanium added, and the mechanical properties of the welding seam are better than 304 stainless steel.
