Material Description

17-4PH (Type 630) is a chromium-copper precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. It combines high strength, hardness (up to 572°F / 300°C), and corrosion resistance equivalent to Alloy 304 or 430 in most media.

Applications

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

Alternative Grade Comparison

Alternative Grade	Reason for Choosing 17-4PH
431	431 has higher toughness but 17-4PH offers better strength
416	416 is free-machining but 17-4PH provides superior strength
316	316 has higher corrosion resistance but much lower strength
2205	2205 has better corrosion resistance with lower strength

Heat Treatment

Solution treatment (Condition A): Heated at 1040°C for 0.5 h, then air-cooled to 30°C. Small sections can be oil quenched.

H1100	593	4	35	970-1120
H1150	621	4	33	930-1080

Processing Characteristics

Welding: Can be welded using all conventional methods without pre-heating. Care should be taken to prevent weldment stresses.

Machining: Can be machined in solution-treated condition with machining rates similar to grade 304 steels.

Product Applications

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