Stainless 17-7 PH Type 17-7 PH Precipitation-Hardening Stainless Steel in sheet and strip forms provide valuable property combinations particularly well suited for aerospace applications. This special alloy also provides benefits for other applications requiring high strength and good corrosion resistance, as well as excellent properties for flat springs up to 600°F (316°C). 17-7PH provides high strength and hardness, excellent fatigue properties, good corrosion resistance and minimum distortion on heat treatment. Resistance to Corrosion: Corrosion resistance of Type 17-7PH stainless steel in all heat-treated conditions, like other types of stainless steels - will develop superficial rust in some environments. However, after exposure of one or two years, the amount of rust present is little more than that present at six months. It may be subject to cracking when exposed under stress in environments containing hydrogen sulfide Features • Provides valuable property combinations particularly well suited for aerospace applications • Provides benefits for other applications requiring high strength and good corrosion resistance • High strength and hardness • Excellent fatigue properties Applications • Aerospace applications • Chemical processing equipment • Oil and petroleum refining equipment • Food processing equipment • General metalworking
