A variant of 17-4 PH designed with better transverse toughness and ductility. 2. Austenitic Alloys

Age‑hardening (also called precipitation‑hardening) is a heat‑treatment process that produces exceptionally high strength in stainless steels without sacrificing corrosion resistance. The process involves a solution‑annealing step followed by a controlled aging treatment that precipitates fine intermetallic particles, dramatically increasing strength and hardness. This family of materials offers a unique combination of:

Type 630 is the most commonly ordered grade under this specification. It is a martensitic precipitation‑hardening stainless steel containing approximately 17% chromium and 4% nickel, plus copper and niobium/tantalum as precipitation‑hardening elements. astm a564 pdf

A modification of 17-4 PH designed to provide greater toughness and better transverse properties.

Due to the versatility unlocked by its varied heat treatments, ASTM A564 material is selected for high-stress components operating in mildly corrosive environments: A variant of 17-4 PH designed with better

Due to their superior properties, ASTM A564 steels are used in demanding environments:

These can be produced via hot rolling, extruding, or forging. Why "Age-Hardening"? The process involves a solution‑annealing step followed by

Unlike standard 304 or 316 stainless (which work-harden), A564 materials are precipitation-hardening (PH). They start soft for machining, then undergo a low-temperature heat treatment to achieve tensile strengths exceeding 150 ksi (1035 MPa).

Rounds, squares, hexagons, bar shapes, angles, tees, and channels produced via hot rolling, extruding, or forging. Mechanical Properties:

Comparable to standard 304 stainless steel in most atmospheric environments.
