Monel K500 Features:

These amplified properties, strength and hardness, are obtained by adding aluminum and titanium to the nickel-copper base and by a thermal processing used to effect precipitation, typically called age hardening or aging.When in the age-hardened condition, Monel K-500 has a greater tendency toward stress-corrosion cracking in some environments than Monel 400.


Alloy K-500 has approximately three times the yield strength and double the tensile strength when compared with alloy 400.Plus, it can be further strengthened by cold working prior to precipitation hardening. The strength of this nickel steel alloy is maintained to 1200° F but stays ductile and tough down to temperatures of 400° F. Its melting range is 2400-2460° F.

Hot Forming

Proper temperature during deformation is themost  important  factor  in  achievement  of  hot  malleability.Maximum  recommended  heating  temperature  for  hot-working  MONEL alloy  K-500  is  2100°F.  Metal  should  becharged  into  a  hot  furnace  and  withdrawn  when  uniformlyheated. Prolonged soaking at this temperature is harmful. If a delay occurs, such that the material should be subjected toprolonged soaking, the temperature should be reduced to orheld  at  1900°F  until  shortly  before  ready  to  work,  thenbrought  to  2100°F.


When  the  piece  is  uniformly  heated,  itshould  be  withdrawn.  In  the  event  of  long  delay,  the  workshould be removed from the furnace and water-quenched.The hot-working temperature range is 1600° to 2100°F. Heavy  work  is  best  done  between  1900°  and  2100°F; working  below  1600°F  is  not  recommended.  To  producefiner grain in forgings, the final reheat temperature should be2000°F and at least 30% reduction of area should be taken inthe last forging  operation.


When hot working has been completed, or when it is necessary for MONEL alloy K-500 to cool before furtherhot  working,  it should not be allowed to cool in air butshould be quenched from a temperature of 1450°F or higher.If  the piece is allowed to cool slowly it will self-heat-treat(age-harden) to some extent,  and stress will be set up  that may lead to thermal splitting or tearing during subsequentre heating. 


In addition, quenched material has better response to age hardening, since more of  the age-hardening constituent is retained in solution.The surface of the material will be oxidized to a lesser degree and will be easier to pickle if it is quenched in watercontaining about 2% by volume of alcohol.


Cold Forming

In the annealed condition, alloy K-500 canbe cold-worked by standard procedures. Although the alloyrequires  considerable  power  to  form,  it  has  excellentductility. Its increase in hardness with increasing cold work,in  comparison  with  other  materials.
