The extent of resistance against corrosion is derived with the hardening and polishing of SS 403 Plates. The SS 403 Plates can withstand the reactions of oxidation up to 760OC. The SS 403 Plates might gain better mechanical qualities if they are forged and tempered under cooler temperatures.
The following table shows the physical properties ofgrade 403 stainless steel.
Properties | Metric | Imperial |
Density | 7.80 g/cm3 | 0.282 lb/in3 |
Properties | Metric | Imperial |
Thermal expansion co-efficient (@0-100°C/32-212°F) | 9.90 μm/m°C | 5.50 μin/in°F |
Thermal conductivity (@500°C/932°F) | 21.5 W/mK | 149 BTU in/hr.ft2.°F |
Stainless steels are high-alloy steels with good corrosion resistancedue to the presence of large amounts of chromium in these steels. The combination of martensitic and ferritic steelsforms a fourth group of stainless steels known as precipitation-hardenedsteels.
