403 stainless steel ( 13Cr- Low Silicon content type )


403 alloy is a corrosion and heat resistant 12% Cr martensitic stainless steel.

This alloy offers a wide range of mechanical properties that are obtainable by appropriate heat treatments.

It is easily hardened by oil, fan or air cooling and may be tempered at temperatures of up to 1350°F (732°C)

to improve fracture toughness. Oil or fan cooling is required in thicker sections.


403 alloy has a composition that falls within the limits designated for 410 stainless.

however, it has a tighter range of chromium content and lower maximum silicon and nickel contents.

This composition was developed to meet the exacting requirements of turbine blade constructions,

which demand a material that combines corrosion resistance with a high elastic limit and high impact strength.

The following table shows a comparison of the nominal composition of 403 alloy with that of 410 material.

Heat treatment of 403 stainless steel

403 stainless steel may be annealed at 1500-1650°F (816-899°C),

followed by a slow cool to 1100°F (593°C), and a final air cool.

403 material may be fully hardened by oil quenching from 1650-1800°F (899-982°C).

Light sections may be hardened by air or fan cooling.

This alloy will harden, to varying degrees, when cooled from temperatures above

1500°F (816°C) unless it is slowly cooled to below the critical temperature or held for

sufficient length of time at a temperature below the critical temperature.

Tempering may be done at a temperature between 400°F (204°C) and 1400°F (760°C),

but it 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 range, strength and hardness decrease while ductility and toughness increase as the

tempering temperature is raised.



403 stainless widely used for turbine blade and high stress fine stainless steel, heat-resistant steel.
