403 Stainless steel CHEMICAL COMPOSITION,403 Stainless steel MACHINABILITY

403 Stainless steel are high-alloy steels with good corrosion resistance due to the presence of large amounts of chromium in these steels. Most of the stainless steels contain about 10% of chromium.

403 Stainless steel CHEMICAL COMPOSITION
Carbon 0.15 max
Manganese 1.00 max
Phosphorus 0.040 max
Sulfur 0.030 max
Silicon 0.50 max
Chromium 11.5-13.5
Iron balance

403 Stainless steel MACHINABILITY
200-240 Brinell hardness or cold-drawn condition recommended
Use chip curler cutting tools when turning
Grind slight flat on cutting lip face when drilling
Highly concentrated sulfur oil
Turn: 40-80 sfpm
Mill: 35-70
Broach: 8-15
Ream: 20-60

403 Stainless steel WORKABILITY
May be cold worked
Easily drop or hammer forged
Preheat 2x as long as carbon steel
Preheat to 1400° to 1450°F (760° to 788°C), then rapid heat to 2050° to 2150°F (1121° to 1177°C)
Reheat once temperature drops to 1450° to 1600°F (788° to 871°C)
Bury in dry lime or ash to slow cool
