Diferencias clave
304 vs. TP304
- Estándar: 304 is a national standard (0Cr18Ni9), while TP304 follows the American standard (Tube/Pipe).
- Composición: TP304 has slightly higher chromium content (≥18%), enhancing its corrosion resistance and increasing its price slightly compared to 304.
304 vs. 304l
- Contenido de carbono: 304 contains ≤0.08% carbon, while 304L contains ≤0.03% carbon.
- Uso: 304 is a general-purpose stainless steel suitable for equipment and parts requiring good corrosion resistance and formability. 304l, with lower carbon content, is used in applications requiring welding, minimizing carbide precipitation in the heat-affected zone to prevent intergranular corrosion.
