2. Material Introduction

17-4PH / ASTM S17400

Steel 17-4 PH is a martensitic precipitation-hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties at temperatures up to 600°F(316°C), good toughness in both base metal and welds, and short-time, low-temperature heat treatments that minimize warpage and scaling.

2.1 The characteristics of 17-4PH:

(1) Formability

(2) Easy to adjust the level of intensity

(3) Good attenuation property

(4) Resistance to corrosion fatigue

(5) Strong anti-drop performance

2.2 The applications of 17-4PH:

(1) Offshore (foils, helicopter deck platforms, etc.)

(2) Food industry

(3) Pulp and paper industry

(4) Aerospace (turbine blades, etc.)

(5) Nuclear waste cask
