The is the standard specification for hot-rolled and cold-finished age-hardening stainless steel bars and shapes . It is a critical reference for materials requiring high strength and corrosion resistance, most notably the 17-4 PH (Grade 630) alloy. Core Specification Scope

Mechanical property requirements (tensile strength, yield strength, elongation, and hardness) Heat treatment conditions and temperatures

Provides maximum ductility and impact toughness, though it lowers the overall tensile and yield strength. Mechanical Properties Comparison (Grade 630 / 17-4 PH) astm a564 pdf

| Standard | Title | Relationship to A564 | |---|---|---| | | General Requirements for Stainless Steel Bars, Billets, and Forgings | Sets general dimensional, tolerance, and finish requirements | | A705/A705M | Age‑Hardening Stainless Steel Forgings | Companion specification for forged products | | A314 | Stainless Steel Billets and Bars for Forging | Governs billets intended for reforging | | A370 | Mechanical Testing of Steel Products | Defines tension and hardness test procedures | | A751 | Chemical Analysis of Steel Products | Defines chemical composition verification methods |

The standard includes numerous alloys, but the most prominent are precipitation-hardening (PH) stainless steels. The is the standard specification for hot-rolled and

Approximately 17% Chromium and 4% Nickel, with copper addition. Common Designation: UNS S17400, AMS 5643, Grade 630.

A physical book is cumbersome, but a allows you to instantly find keywords like "Condition H900" or "Tensile Strength." Mechanical Properties Comparison (Grade 630 / 17-4 PH)

The standard regulates standard shapes produced through hot rolling, extruding, or forging: Squares Hexagons Angles, tees, and channels Billets or bars intended for reforging Chemical Composition Requirements
