  17-4PH Stainless Steel

 

17-4 Precipitation Hardening also known as Type 630 is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance. High strength is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius).

 

General Properties

Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines high strength, hardness (up to 572°F / 300°C), and corrosion resistance.

Mechanical properties can be optimized with heat treatment. Very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved.

The grade should not be used at temperatures above 572°F (300°C) or at very low temperatures. It has adequate resistance to atmospheric corrosion or in diluted acids or salts where its corrosion resistance is equivalent to Alloy 304 or 430

 

ApplicationsStandards
  • Offshore (foils, helicopter deck platforms, etc.)
  • Food industry
  • Pulp and paper industry
  • Aerospace (turbine blades, etc.)
  • Mechanical components
  • Nuclear waste casks
  • ASTM A693 grade 630 (AMS 5604B) UNS S17400
  • EURONORM 1.4542 X5CrNiCuNb 16-4
  • AFNOR Z5 CNU 17-4PH
  • DIN 1.4542

Corrosion Resistance

Alloy 17-4 PH withstands corrosive attacks better than any of the standard hardenable stainless steels and is comparable to Alloy 304 in most media.

If there are potential risks of stress corrosion cracking, the higher aging temperatures then must be selected over 1022°F (550°C), preferably 1094°F (590°C). 1022°F (550°C) is the optimum tempering temperature in chloride media.

1094°F (590°C) is the optimum tempering temperature in H2S media.

The alloy is subject to crevice or pitting attack if exposed to stagnant seawater for any length of time.

It is corrosion resistant in some chemical, petroleum, paper, dairy and food processing industries

 (equivalent to 304L grade).

 

 

 

GENERAL PROPERTIES

 

Allegheny Ludlum's AL 17-4™ Precipitation Hardening

 

Alloy (S17400), Type 630, is a chromium-nickel-copper

 

precipitation hardening stainless steel used for applications

 

requiring high strength and a moderate level of

 

corrosion resistance. High strength is maintained to approximately

 

600°F (316°C).

 

The S17400 alloy is martensitic in structure in the annealed

 

condition and is further strengthened by a low

 

temperature treatment which precipitates a copper containing

 

phase in the alloy. In comparison to many alloys

 

in the precipitation hardening family, the S17400 alloy

 

requires a simple heat treatment; a one step process

 

conducted at a temperature in the range 900°F (482°C)

 

to 1150°F (621°C) depending on the combination of

 

strength and toughness desired. A wide range of properties

 

can be produced by this one step heat treatment.

 

Heat treatment in the 900°F (482°C) range produces

 

highest strength, although slightly less than that of alloys

 

like S17700 or S15700. The latter precipitation hardening

 

alloys generally require more steps to complete

 

heat treatment.

 

FORMS AND CONDITIONS

 

The Allegheny Ludlum AL 17-4 Precipitation Hardening

 

Alloy is furnished as plate. Long products are produced

 

by Allvac, an Allegheny Technologies Company. In all

 

forms, the material is furnished in the annealed condition

 

CORROSION AND

OXIDATION RESISTANCE

Tests have shown that the corrosion resistance of

AL 17-4 Precipitation Hardening Alloy is comparable to

that of Type 304 stainless steel in most media. In general,

the corrosion resistance of AL 17-4 alloy is superior

to that of the hardenable 400 series stainless steels.

 

As with other precipitation hardening alloys, AL 17-4 Precipitation

Hardening Alloy is more susceptible to stress

corrosion cracking at peak strength. Consequently, in

applications in which chloride stress corrosion cracking

is a possibility, the material should be precipitation hardened

to produce the lowest hardness compatible with

the intended end use. This is done by heat treating at

the highest temperature which will produce suitable

minimum properties.

 

Material in the annealed condition should not generally

be put into service. In this condition, the material has

an untempered martensite structure and is less ductile

than aged material. The untempered martensite may

be subject to unpredictable brittle fractures. In corrosive

environments, the untempered martensite is more

sensitive to embrittling phenomena such as hydrogen

embrittlement than material which has had one of the

precipitation hardening heat treatments. Similarly,

untempered martensite is more sensitive to chloride

stress corrosion cracking than material in which the

martensite has been tempered.

 

The oxidation resistance of the AL 17-4 alloy is superior

to that of 12 percent chromium alloys like Type 410, but

slightly inferior to that of Type 430. Precipitation hardening

will produce surface oxidation

 

 

HEAT TREATMENT

The AL 17-4 Precipitation Hardening Alloy is furnished

in the annealed condition. This is also called the solution

heat treated condition, or Condition A. Annealing is

conducted by heat treating at approximately 1900°F

(1040°C) to 1950°F (1065°C) and cooling to room temperature.

In this condition, the material possesses a

martensitic structure. As a martensitic structure, the

AL 17-4 alloy possesses a relatively high strength and

hardness in the annealed condition. The strength and

hardness of the material is generally somewhat lower

in the H 1150 overaged condition.

 

To develop further increase in strength, the annealed

material is precipitation hardened by heat treatments at

900°F (482°C). Heat treatments above 1075°F (579°C)

generally result in material softer than material in the

annealed condition. The heat treatments are usually

specified as follows:

 

The precipitation hardening reaction can be driven past

peak strength by heat treating at an excessively high

temperature or by excessive time at the precipitation

hardening temperature. The table on page 3 shows the

effect of higher temperature heat treatment. A less dramatic

downward shift in strength results from excessively

long precipitation hardening times.

 

The heat treatments used for the AL 17-4 Precipitation

Hardening Alloy are summarized below.

General Information

 

Principal Design Features

One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.


Applications

Commonly used in both aircraft and gas turbines, nuclear reactor, paper mill, oil field, and chemical process components.


Machinability

Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.


Forming

This alloy is capable of being only mildly formed. If forming is required, do so in the overaged condition for best results.


Welding

Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.


Heat Treatment

CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.


Forging

Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.


Hot Working

17-4 PH can be easily hot worked using most of the common processes. It is suggested that material be solution treated at 1900 F(1038 C) then formed during cooling while the material is still austenitic. Post-work solution treatment is required prior to final hardening.


Cold Working

Despite its high initial yield strength, 17-4 can be cold worked successfully by most common methods.


Annealing

1900 F (1038 C), hold for 1/2 hour, rapid cool.


Hardening

This alloy has good ductility and may be readily formed by all conventional methods. Because the alloy is stronger than regular steel it requires more powerful equipment to accomplish forming. Heavy-duty lubricants should be used during cold forming.
