17-4 Stainless Steel
SAE Type 630 stainless steel is a type of martensitic precipitation-hardening stainless steel that is more often called 17-4 PH or just 17-4. It is also known as UNS S17400. It has between 15–17.5% chromium, 3–5% nickel, and 3–5%, copper. It gets its name from the fact that it is made up of about 17% Chromium and 4% Nickel. It also contains 4% Copper and 0.3% Niobium. 17-4 PH is also known as stainless steel grade 630.
17-4 stainless is martensitic stainless steel that gets stronger with age and is also resistant to corrosion. A short, simple, and low-temperature treatment are all it takes to make something harder. 17-4 is much easier to weld than most martensitic stainless steels, like type 410. Because it is strong, doesn’t rust, and is easy to work with, 17-4 stainless can be a cheaper alternative to high-strength carbon steels and other stainless grades.
When the metal is heated to 1900°F for solution treatment, its structure is austenitic, but when it cools to room temperature, its structure changes to a low-carbon martensitic structure. This change won’t be done until the temperature goes down to 90°F. The alloy gets stronger when it is heated to temperatures between 900 and 1150°F for one to four hours. This process of hardening also tempers the martensitic structure, making it more flexible and tough.

15-5 PH Stainless Steel – AMS 5659:
15-5 PH stainless steel is a type of stainless steel that is known for its high strength, hardness, and corrosion resistance. It contains approximately 15% chromium and 5% nickel, and can be further strengthened through a single low-temperature heat treatment. Compared to 17-4 PH stainless steel, 15-5 PH has better transverse toughness and ductility, as well as better mechanical properties in larger cross-sections and better forgeability. It is also readily weldable and can be machined in a variety of thermal conditions. Lakshya Steel is a leading distributor and supplier of 15-5 PH stainless steel in a variety of forms, including round bar, flat bar, square bar, plate, sheet, block, and billet.
