416 Stainless Steel Data

Chemical Composition
    Chrome: 12.0 - 14.0 Nickel: -- Carbon: .15 max. Manganese: 1.25 max. Silicon: 1.00 max. Molybdenum: .06 max. Sulfur: .15 min.

Welding  is not recommended, as the high sulfur content creates porosity.  All hot work procedures should commence following uniform heating to 2100-2250 F (1149-1232 C). Hot work below 1700 F (927 C) may result in cracking.  This alloy will accept only minor cold working. Severe deformation will result in cracking.  Annealing - 1200-1400 F (650-760 C), air cool. For maximum softness, 1500-1650 F (816-900 C), furnace cool.  Temper to achieve properties desired. Avoid tempering in the range of 750-1050 F (399-566 C) to avoid a decrease in impact strength and corrosion resistance.  To harden : Soak at 1700-1850 F (927-1010 C) oil quench.
