17-4 PH Stainless Steel (SAE type 630 stainless steel), is the martensitic precipitation-hardened stainless steel casting grade. Typical usage of 17-4 stainless steel castings is where high strength and a modest level of corrosion resistance is required.
Stainless steel 17-4 PH (UNS J92180), Type 630, is a chromium-nickel-copper precipitation-hardening martensitic stainless steel with an addition of niobium. 17-4 PH combines high strength and hardness with good corrosion resistance. 17-4 is a common named used by two or more producers, not a trademark.And it's not official material grade name too.

Grade 17-4 stainless steel can be cold worked using common techniques in spite of its high initial yield strength. Annealing. Grade 17-4 stainless steel is annealed at 1038°C (1900°F) for 0.5 h followed by cooling rapidly. Hardening. Grade 17-4 stainless steel has high ductility, and can be formed using all conventional techniques.
17-4 Precipitation Hardening also known as Type 630 is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance. High strength is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius). General Properties
Alloy 17-4PH (UNS S17400), Type 630, is a chromium-nickel-copper precipitation-hardening martensitic stainless steel with an addition of niobium. 17-4PH combines high strength and hardness with good corrosion resistance. 17-4 is a common named used by two or more producers, not a trademark. And it's not official material grade name too.
Type 17-4 PH stainless steel contains between 15-17.5% of chromium in its composition. In this regard, a seagoing vessel's pump and valve parts are made of type 17-4 PH stainless steel. Most of the parts of that ship that you went on that annual cruise are made from type 17-4 PH stainless steel.
AL 17-4 Precipitation Hardening Alloy is comparable to that of Type 304 stainless steel in most media. In gen-eral, the corrosion resistance of AL 17-4 alloy is supe-rior to that of the hardenable 400 series stainless steels. As with other precipitation hardening alloys, AL 17-4 Pre-cipitation Hardening Alloy is more susceptible to stress
17-4PH Precipitation Hardening Stainless Steel. An American aerospace grade stainless steel that contains 4% copper and may be hardened by a single low temperature precipitation hardening heat treatment, producing excellent mechanical properties at a high strength level.
17-4 PH Stainless Steel is the most widely used stainless steel casting alloy of all the precipitation-hardening stainless steels. It contains approximately 15-17.5% chromium and 3-5% nickel, as well as 3-5% copper.
SS316 and 17-4 PH are common used two types of stainless steel grades for investment casting. 316 is typical austenite stainless steel casting grade, while 17-4 PH stainless steel is precipitation hardening material grade, which are all defined in American standards.When you compare Stainless Steel 17-4 ph vs 316 for casting, it is obvious that 17-4 PH has the higher hardening content.
Material 17-4: Stainless Steel Castings, ... A stainless steel casting must have low carbon content to perform well in corrosive environments. Thus, higher carbon content will improve the performance of heat-resistant grades in high temperature situations and improve their strength.
Cast stainless steel is made by pouring liquid metal into a molding container with a specific shape. Wrought stainless steel starts out at a steel mill, where continuous casters make stainless into ingots, blooms, billets, or slabs. These raw manufacturing materials must then be shaped by further work.
