1.4418(X4CrNiMo16-5-1,Z6CND16-05-01,AISI S165M,X4CRNIMO16.5.1,X 4 Cr Ni Mo 16-5-1,Z 6 CND 16-05-01) Stainless is a martensitic stainless steel specially designed for those applications requiring high mechanical properties combined with improved corrosion resistance relative to traditional martensitic steels.
1.4418 Stainless is also offered as an enhanced machining variant, 1.4418  stainless, which obtains an enhanced machinability characteristic through controlled addition of sulfur without degrading strength or corrosion resistance. 1.4418 EM Stainless contains differentiated micro constituents for easier machining production.
Corrosion Resistance
This alloy shows good corrosion resistance to mild atmospheres, both in annealed and heat-treated conditions. It resists corrosion in many industrial and domestic environments as well as potable and mine waters.
For optimum corrosion resistance, surfaces must be free of scale, lubricants, foreign particles, and coatings applied for drawing and heading. After fabrication of parts, cleaning and/or passivation should be considered.
Annealing
This alloy is typically annealed at 1112°F - 1200°F (600°C - 650°C), followed by slow cooling in air. Heat uniformly to the selected temperature.
Hardening
Heat to 1740°F - 1920°F (950°C - 1050°C), followed by oil quench. Small sections can be hardening by air cool.
Tempering
QT900 properties are achieved by tempering at 1025°F - 1145°F (550°C - 620°C) for 8 hours followed by oil or air cool. Alternately, material may be treated using two cycles, 4 hours each followed by oil or air cool. This alloy may suffer temper embrittlement if tempered at 785°F - 1022°F (450°C - 550°C), or slow cool at this temperature range.
