Technical Information for 17-7

Alloy
UNS Number
SAE Number
  17-7
  S17700
  N/A


GENERAL PROPERTIES

The 17-7 alloy is a chromium-nickel-aluminum precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance.

The 17-7 alloy has been available for many years and has found application in aerospace and many spring type applications requiring high strength. The 17-7 alloy may be formed in a soft austenitic condition and hardened to a high strength level by low temperature heat treatments. The low temperature heat treatment required for developing high strength allows minimum distortion compared to conventional quench and temper hardening processes. In addition to material produced by the standard refining procedures, material which has been vacuum arc or electroslag remelted is available for further increase in resistance to fatigue, for those applications subject to cyclic stresses.



RESISTANCE TO CORROSION

Tests have show that the corrosion resistance of the 17-7 alloy is comparable to that of Type 304 stainless steel in most media. In general, the corrosion resistance of 17-7 is superior to that of the hardenable 400 series stainless steels.

WELDING

The 17-7 alloy is weldable by conventional inert gas methods. The precipitation hardening reaction in the alloy is dependent on the presence of aluminum, a reactive element. For this reason, inert gas methods are used to protect against the loss of aluminum.

One of the desirable features of the alloy is the elimination of the need for preheating and postweld annealing procedures needed for conventional hardenable stainless steel materials.



HEAT TREATMENT

One of the conditions in which 17-7 is furnished is the annealed condition, Condition A. In this condition, the material possesses an austenitic structure. As an austenitic material, the 17-7 alloy possesses a relatively low strength. This is the condition in which formability is easiest.

To develop the high precipitation hardened strength of the alloy by heat treatment, starting from Condition A, heat treatments are done to accomplish two necessary steps. The first is a heat treatment which alloys the relatively stable austenite of Condition A to transform to martensite (Austenite Conditioning and Transformation). The second is a precipitation hardening heat treatment to further strengthen the material. The austenite is easier to transform to martensite using a lower temperature heat treatment. For this reason, Condition TH 1050 uses a 1400° F (760° C) heat treatment to produce a martensite transformation around room temperature, and this is followed by a precipitation hardening heat treatment at 1050° F (565° C). If Condition RH 950 is desired, the austenite conditioning heat treatment is conducted at 1750° F (955° C). In this case, the martensite transformation is not complete until the material is held for some time at –100° F (-73° C). When transformation is complete, the material is precipitation hardened at 950° F (510° C) to Condition RH 950.

Because the precipitation hardening reaction can be driven past peak strength by high temperature or excessive time at the aging temperature, higher temperature or longer time precipitation hardening heat treatments produce lower strength levels.

When 17-7 with an austenitic structure is cold worked by substantial deformation, a transformation to martensitic structure results from the deformation. In this condition, Condition C, the material may be precipitation hardened directly by heat treatment at 900° F (482° C) to Condition CH 900.

Technical Information for 410

Alloy
UNS Number
SAE Number
  410
  S41000
  51410


GENERAL PROPERTIES

Type 410 is a hardenable, straight chromium stainless steel which combines superior wear resistance of high carbon alloys with the excellent corrosion resistance of chromium stainless steels. Oil quenching these alloys from temperatures between 1800°F to 1950°F (982 to 1066° C) produces the highest strength and/or wear resistance as well as corrosion resistance.

This alloy is used when strength, hardness, and/or wear resistance must be combined with corrosion resistance.



RESISTANCE TO CORROSION

Type 410 exhibits good corrosion resistance to atmospheric corrosion, potable water, and to mildly corrosive chemical environments because of its ability to form a tightly adherent oxide film which protects their surfaces from further attack. Exposure to chlorides in everyday type activities is generally satisfactory when proper cleaning is performed after exposure to use.

For maximum corrosion resistance to chemical environments, it is essential that the stainless steel surface be free of all heat tint or oxide formed during forging, annealing, or heat treating. Al surfaces must be ground or polished to remove any traces of oxide and surface decarburization. The parts should then immersed in a warm solution of 10-20% nitric acid to remove any residual iron. A thorough water rinse should follow the nitric acid treatment.

HEAT TREATMENT

To anneal this alloy, heat to 1500-1550° F (815-842° C) and hold for one hour per inch of thickness and furnace cool to room temperature. Such annealing should produce a Brinell hardness of 126-192 HB.

A hardening heat treatment is necessary to bring out the maximum hardness and wear resistance. Since these materials absorb heat very slowly, they should be heated gradually and allowed to remain at temperature long enough to ensure uniform temperature in thick sections. For maximum strength, hardness, and corrosion resistance, slowly heat the alloy to 1800° F (982° C) and quench to room temperature in oil. For thin sections, air cooling can be substituted for the oil quench. If retained austenite is known to be present after the austenitizing and quench to room temperature, additional hardening response may be achieved by sub-zero cooling to about –100° F (-73° C). The as-quenched structure of fresh martensite is quite brittle and should be stress-relieved or tempered at approximately 400 to 500° F (204 to 260° C) to restore some ductility. During tempering between approximately 300° F (149° C) and 600° F (316° C), a relaxation of the martensite structure occurs whereby the volumetric stresses associated with the formation of martensite upon quenching are relieved. As a result, the martensite still exhibits its high hardness and wear resistance properties but some ductility is introduced at the loss of a few pints of hardness.
