The name comes from the chemical makeup which is approximately 17% and 4% nickel. In order to keep away from discount in mechanical properties, it should not be used over its precipitation hardening temperature. Prolonged publicity to °C ought to be prevented if ambient temperature toughness is crucial.

After hardening heat remedy, machining is troublesome however possible. Then the component must be precipitation hardened to realize the required mechanical properties. Cold forming corresponding to rolling, bending and hydroforming may be performed on 17-4PH but only within the absolutely annealed situation. After chilly working, stress corrosion resistance is improved by re-ageing at the precipitation hardening temperature. Due to the high power of precipitation hardening stainless steels, most functions are in aerospace and different high-know-how industries.

Mechanical Properties

We kept ex inventory of Stainless Steel 17-4PH export shiny and black bar rod. Size can be found from 5mm Dia to 250mm Dia in Imported and Indian make. 630 is a 17-four PH martensitic precipitation hardening stainless-steel with a singular mixture of high strength and good corrosive resistance.


  • The warmth and corrosion resistance of grade 630 are just like that of grade 304 steels.
  • These steel achieve high power and hardness following warmth .
  • The heat and corrosion resistance of grade 630 sheet are similar to that of grade 304 steels.
  • Grade 630 stainless steels sheet are martensitic stainless steels that are precipitation hardened to attain wonderful mechanical properties.

Corrosion resistance is low in the answer treated (annealed) situation and it shouldn’t be used before heat treatment. Yield strengths for precipitation-hardening stainless steels are 515 to 1415 MPa. Cold working before ageing can be utilized to facilitate even higher strengths. 17-4PH Condition has machining traits much like stainless grades 302, 304 and 410.

Arc and resistance welding processes used on commonplace grades of chrome steel are relevant to 17-4PH chrome steel. The low hardness enables , as much as 100mm, to be welded without requiring pre heating. High power is maintained to roughly 600 degrees Fahrenheit (316 levels Celsius). We offer superior quality17-4 Precipitation Hardening, which can be acknowledged as Type 630.

Austenitic precipitation hardening steels retain their austenitic structure after annealing and hardening by ageing. At the annealing temperature of 1095 to 1120°C the precipitation hardening part is soluble. Hardness remains lower than that for martensitic or semi-austenitic precipitation hardening steels. The key to the properties of precipitation hardening stainless steels lies in warmth therapy. The advantage of precipitation hardening steels is that they can be provided in a “solution treated” condition, which is quickly machinable.

The properties talked about under pertain to commonly out there grade 630 bar merchandise in ASTM A564. The specifications will not be just like other types corresponding to forgings and plates. Hardening — Grade 630 stainless steels are age-hardened at low temperatures to attain the required mechanical properties. During the method, superficial discoloration happens followed by shrinkage at zero.10% for situation H1150, and 0.05% for situation H900.

We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
