17-4 stainless is an age-hardening martensitic stainless combining high strength with the corrosion resistance of stainless steel. Hardening is achieved by a short-time, simple low-temperature treatment. Unlike conventional martensitic stainless steels, such as type 410, 17-4 is quite weldable. The strength, corrosion resistance and simplified fabrication can make 17-4 stainless a cost-effective replacement for high strength carbon steels as well as other stainless grades.
At the solution treating temperature, 1900°F, the metal is austenitic but undergoes transformation to a low-carbon martensitic structure during cooling to room temperature. This transformation is not complete until the temperature drops to 90°F. Subsequent heating to temperatures of 900-1150°F for one to four hours precipitation strengthens the alloy. This hardening treatment also tempers the martensitic structure, increasing ductility and toughness.

Why 17-4PH ?
• Easy to adjust the strength level, that is through the changes in heat treatment process to adjust martensite phase transformation and aging
treatment of metal forming precipitation hardening phase.
• Corrosion fatigue resistance and water resistance.
• Welding:In the condition of solid solution,ageing or overageing ,the alloy can be welded in ang way, without preheating.
If demanding the welding strength close to the steel strength of ageing hardened, then the alloy must be solid solution and ageing treatment after welding.
This alloy is also suitable for brazing, and the best brazing temperature is the solution temperature.
• Corrosion resistance：Alloy corrosion resistance is superior to any other standard hardenable stainless steel, in the static water easy suffer from erosion corrosion or cracks.In the petroleum chemical industry, food processing and paper industry with good corrosion resistance.
17-4PH Application field：
• Offshore platforms, the helicopter deck, other platforms.
• Food industry.
• Pulp and paper industry.
• Space (turbine blade).
• Mechanical parts.
• Nuclear waste barrels.
