Heat Treatment for Cast Products at Eagle Alloy

Posted by Nic Tarzwell on 2023 Jun 1

Eagle Alloy provides a wide range of metalcasting services. In addition to casting hundreds of alloy grades that can be formed into virtually any castable shape, our foundry is fully equipped to heat treat the majority of parts we manufacture. In this blog, we’ll be opening the doors to our heat treatment facilities. You’ll get to know what kind of heat treat equipment we utilize to deliver superior products that consistently meet performance expectations.

Casting a part into its required shape does not fully prepare it for a life of service – only heat treatment can ensure a part performs exactly how it should. With the exception of a handful of nickel-based specialty alloys, Eagle Alloy heat treats just about every part that is cast in our facilities. From annealing and normalizing to stress relieving and quenching, we have the furnaces, quench tanks, data and expertise to take a product from inception to delivery.

Introduction to Heat Treatment for Cast Parts

Posted by Nic Tarzwell on 2023 May 16

Metal manufacturers utilize a number of tools to control the mechanical and physical properties of raw materials. An alloy’s chemistry is only one part of the equation: obtaining the final properties can only be achieved through heat treatment. In this introduction, we'll cover the following topics:

  • Why heat treatment is important for metalcasting
  • Heat treatment for carbon steel vs heat treatment for stainless steel
  • The importance of using ASTM standards
  • Key heat treatment processes used by foundries and machine shops

Heat treatment is a broad term describing a range of thermal processes used to control an alloy’s properties. These processes ensure a finished product carries the mechanical and physical properties demanded by its application. Encompassing both heating and cooling, heat treatment incorporates a few distinct and equally important phases:

  1. Ramp-up: heating the metal;
  2. Soak: maintaining the metal at a desired temperature for a specified amount of time;
  3. Cooling: cooling to a specified temperature at a controlled rate and in a controlled environment.
