Cold Drawing of Stainless-Steel Tubes - ON-231

Preferred Disciplines: Mechanical Engineering, Metallurgical Engineering (Master’s or PhD student)
Company: Samuel, Son & Co., Ltd 
Project Length: 4-6 months
Desired start date: Summer/Fall 2019 
Location: Markham, ON
No. of Positions: 1
Preferences: None

About the Company: 

We are a premier manufacturer of specialty engineered stainless steel and high nickel alloy welded and drawn tube used extensively for automotive fuel handling systems, aerospace, heat exchangers, and other demanding applications.

Project Description:

Cold drawing is applied to both stainless steel and high-nickel alloy tubes to achieve high wall-to-OD ratios unattainable by roll-forming and welding to size. Other benefits of cold drawing include metallurgical homogenization of the weld through cold-working and recrystallization, improving the weld profile for ap plications that require clearance, and the ability to achieve and maintain tight dimensional tolerances. Project focus is to develop mathematical models for determining optimal draw schedules and welded shell-size, tooling design, and process parameters.

Research Objectives:

  • Establish mathematical models to optimize the draw schedules based on material mechanical properties, material flow mechanics, equipment load capabilities, and tooling design. (Calculate force, maximum reduction, etc.)
  • Improved methods for designing/specifying tooling
  • Selection of draw lubricants
  • Metal forming simulation software (review of available options)


Methodology is to be developed in conjunction with the supervisor, but should focus on correlating published material properties with a collection of empirical data obtained during controlled R&D runs on production intent equipment.  

Expertise and Skills Needed:

Strong accumen in stainless steel and high-nickel alloy material properties, formability, tooling design, and manufacturing processes.
