Product Description

Type 630 Stainless Steel Rod (17-4PH Stainless Steel Bar)

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. This grade 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).

Applications & Standards

Applications

Offshore equipment (foils, helicopter deck platforms)
Food processing industry
Pulp and paper manufacturing
Aerospace components (turbine blades)
Mechanical components
Nuclear waste casks

Alternative Grade Comparison

Alternative Grade	Reasons for Choosing 17-4PH (630)
431	431 has higher toughness than 17-4PH. Better availability in some sizes.
416	Free-machining martensitic stainless steel - better for repetition machining. Lower cost.
316	Higher corrosion resistance of 316 to resist more severe environments, but with much lower strength than 17-4PH.
2205	Much better corrosion resistance than 17-4PH, with a lower strength (but not as low as 316).

Processing Characteristics

Welding: Grade 630 stainless steels can be welded using all conventional methods without pre-heating. Care should be taken in designing and welding high strength steels to prevent weldment stresses.

Machining: Grade 630 stainless steels can be machined in their solution-treated condition. They have machining rates similar to grade 304 steels.
