Grade 630 (17-4PH) . Grade 630 martensitic precipitation hardening stainless steel has a combination of high hardness and strength after suitable heat treatment. It also has similar corrosion and heat resistance to Grade 304. The terms "Type 630" and "17-4PH" refer to the same grade.
25 kwi 2024 · 17-4 stainless steel, also known as SAE Type 630, is a precipitation-hardening martensitic stainless steel. It is known for its high strength, good corrosion resistance, and easy heat treatment.
17-4 stainless steel. SAE Type 630 stainless steel (more commonly known as 17-4 PH, or simply 17-4; also known as UNS S17400) is a grade of martensitic precipitation hardened stainless steel. It contains approximately 15–17.5% chromium and 3–5% nickel, as well as 3–5% copper. [1]
17-4PH is a widely-used martensitic precipitation-hardening stainless steel with a high concentration of chromium and nickel. It has many favorable properties, including excellent strength, good corrosion resistance, and excellent mechanical properties up to 600 °F (316 °C).
All data and graphs on front page reflect values of H900 heat treated 17-4 PH SS. Markforged represent typical tested values values, while MIM H900 and Wrought H900 represent typical reference values from MPIF Standard 35.
30 wrz 2024 · 17-4 PH stainless steel exhibits excellent corrosion resistance, comparable to that of 304-grade stainless steel. It can tolerate corrosive environments in industries such as aerospace food processing and chemical.
17-4 Stainless is a martensitic chromium-nickel-copper stainless steel in the solution treated (annealed) condition. It can be further hardened to various strength levels by a single precipitation hardening heat treatment that minimizes scaling and distortion.
