Product Description

ASTM A564 Type 630 H1150 Stainless Steel Bar Rod

17-4PH Stainless Steel Overview

17-4 Precipitation Hardening (Type 630) is a chromium-copper precipitation hardening stainless steel designed for applications requiring high strength and moderate corrosion resistance. This alloy maintains high strength up to approximately 600°F (316°C).

Key Characteristics

Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with copper and niobium additions. It combines high strength, hardness (up to 572°F / 300°C), and excellent corrosion resistance. Mechanical properties can be optimized through heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).

Property	Value
Density (kg/m³)	7750
Mean Coefficient of Thermal Expansion 0-100°C (µm/m/°C)	10.8
Thermal Conductivity at 100°C (W/m·K)	18.4
Specific Heat 0-100°C (J/kg·K)	460
Electrical Resistivity (nΩ·m)	800

Heat Treatment

Grade 630 stainless steels are solution treated at 1040°C for 0.5 hours followed by air cooling. Age hardening at low temperatures achieves required mechanical properties with minimal distortion.

Machining & Welding

This alloy can be machined in solution-treated condition with rates similar to grade 304 stainless steel. It can be welded using all conventional methods without pre-heating requirements.

Typical Applications

Engine components
High strength boat propeller shafts
Plastic molding dies
Valves and gears
