Tempering Stainless 403 plate may be done at a temperature between 400°F (204°C) and 1400°F (760°C), but Stainless 403 plate is advisable to avoid the 800°F (427°C) to 1100°F (593°C) range due to a decrease in impact properties and corrosion resistance. Outside of this Stainless 403 plate range, strength and hardness decrease while ductility and toughness increase as the tempering temperature is raised.
