The manufacturing of stainless steel parts is evolving, and with the help of technology, we’ve come a long way to get desired CNC machined parts in no time. Are you fascinated by what stainless steel can achieve in the manufacturing sector? Find out about the manufacturing process of parts. 

Process of getting desired custom stainless steel parts 

Stainless steel has to go through various steps for the desired product. When making the stainless steel parts the manufacturer has to keep the grade in mind. They need to choose the steel grade according to the industry. Here are the three most common grades: 

  • Stainless Steel Grade 302
  • Stainless Steel Grade 303
  • Stainless Steel Grade 430F

Once you have decided on the steel grade and gathered the raw materials, the rest of the manufacturing process can begin. Here are the steps: 

  • Melting the raw materials
  • Removal of excess carbon
  • Tuning
  • Forming the metal
  • Heat treatment
  • Descaling
  • Cutting and shaping
  • Finishing 

 

#1. Melting the raw materials 

In a furnace, typically an electric one, stainless steel components heat to their melting point, a process that usually takes 8 to 12 hours. Once the metal melts, the production process forms common shapes such as slabs, blooms, billets, and rods.

#2. Removal of excess carbon

People place the molten material in the VOD or AOD system to remove any excess carbon present in stainless steel. Depending on how much carbon you want to remove will affect the quality of the final product. It can impact the tensile strength and hardness of the machined part. It can result in a standard or low-carbon variant of the alloy. 

#3. Tuning 

The next step is to fine-tune the quality of the final product. For this, the manufacturers need to stir, helping to distribute and remove the specific components from the mixture. It ensures that the stainless steel is of uniform quality. And will meet the specifications set by the manufacturer. 

#4. Forming the metal 

The semi-finished steel shapes now undergo a series of forming operations. For example, stainless steel is hot-rolled, and the blooms and bars mentioned in point 1 get converted to bar and wire. The slabs get formed into plates, strips or sheets. It is easier to turn semi-finished shapes into bars as they are the most versatile stainless steel form. It is all-around because it comes in all grades and sizes. You have plenty of options to choose from for different applications. 

#5. Heat treatment 

The heat treatment is the following procedure. It get heated during annealing. Then it’s cooled down in a controlled environment. The reason for this heat treatment is it relieves the pent-up stress that is present in the stainless steel. It softens the material to make it suitable for a variety of applications. The operator has to be careful while carrying out the annealing process about the control conditions as even minute changes in the pressure, temperature, duration or cooling rate result in a faulty product. 

#6. Descaling 

On the surface, many scales form. It occurs as a result of the heat treatment process. People can use descaling to remove these scales. One of the popular methods is pickling to carry out the descaling process. 

#7. Cutting and shaping

People cut and shape it to manufacture the ideal product for the application. The specific operations used to cut the stainless steel will vary depending on the size and the shape of the bloom and the final product. The manufacturer may cut the steel mechanically using large metal shears if they produce thick metal plates. If you want to cut thin metal sheets you can use CNC punch or laser cutting machines. MDA’s manufacturing team manufactures custom metal cutouts from metal sheet plates by using up-to-date machining processes. 

#8. Finishing 

The manufacturer might apply different surface finishes according to the requirements of the final product. We apply finishing to enhance the product’s appearance, smooth the part, and ensure it’s easier to clean, which is crucial in most industries.

Factors To Look at When Selecting Steel Grade For CNC Machining 

Steel comes in various grades and types, each with its own set of properties and characteristics. It can be a reason for manufacturers to decide which is ideal for manufacturing needs. Here are some pointers that will help to make a choice.

  • Tensile strength 

The tensile strength of a steel grade should get considered when selecting one. When a material gets subjected to tension, it simply refers to the quality of resistance it exhibits. It shouldn’t be possible to determine whether the steel grade is suitable for the job in a short time before it sustains some form of damage. The tensile strength is measured using an extensometer, which measures how much peak force the sample can withstand before breaking.

 

  • Machinability properties 

The machinability of various steel grades gets determined by how easily they get modified. When machining steel products, steel manufacturing plants typically use a variety of processes. These can be simple techniques like cutting or more complex techniques like drilling and shearing. The time it takes a particular tool to make cuts or incisions on a steel sample is the most common way to measure this property.

 

  • Operating environment

Before selecting the appropriate grade, it is critical to consider the steel product’s operating environment. High temperatures, pH levels, and frequency of impact are just a few factors. Furnaces, for example, may affect the utility and functionality of the steel material around them over time.

 

  • Corrosion resistance 

Corrosion resistance is an ideal quality needed for all steel parts for various industrial applications. Moreover, different grades have variations in their level of resistance. High-corrosion resistance is necessary for parts used in the marine industry (saltwater). CNC stainless steel is the most resistant among the metal grades.
