Cnc Machining 316 Stainless Steel


316 stainless steel is a widely used stainless steel alloy that belongs to the austenitic family of stainless steels. It is composed of iron, chromium, nickel, molybdenum, and small amounts of other elements. The specific composition of 316 stainless steel is as follows:

The Composition Of 304 Stainless Steel


  • Iron (Fe): Balance (approximately 62-69%)
  • Chromium (Cr): 16-18%
  • Nickel (Ni): 10-14%
  • Molybdenum (Mo): 2-3%
  • Carbon (C): Maximum 0.08%
  • Manganese (Mn): Maximum 2%
  • Silicon (Si): Maximum 0.75%
  • Phosphorus (P): Maximum 0.045%
  • Sulfur (S): Maximum 0.03%

CNC machining of 316 stainless steel involves using computer-controlled machines to remove material from a workpiece made of this specific stainless steel alloy. The process follows the principles of CNC (Computer Numerical Control) machining, where the machine’s movements are precisely controlled by computer programs to achieve the desired shape and dimensions. CNC machining techniques like milling, turning, drilling, and threading can be applied to 316 stainless steel. These processes involve removing material from the workpiece to create the desired shape, features, and dimensions. CNC machines can perform these operations accurately and efficiently.

Benefits Of 316 Stainless Steel Machining


CNC machining of 316 stainless steel offers several benefits, including:

  • Precision and repeatability in achieving tight tolerances and complex geometries.
  • Ability to produce high-quality surface finishes on the machined components.
  • Versatility to create various parts and components for industries such as aerospace, automotive, medical, and more.
  • Efficient production with reduced labor costs and increased productivity through automation.

Mechanical Properties Of Stainless Steel Alloy 316


The mechanical properties of stainless steel alloy 316 are as follows:

  • Tensile Strength: The tensile strength of stainless steel 316 is typically around 515 MPa (75,000 psi). This indicates the maximum amount of tensile stress the material can withstand before it fails or fractures.
  • Yield Strength: The yield strength of stainless steel 316 is usually around 205 MPa (30,000 psi). This is the stress at which the material exhibits permanent deformation or begins to yield under tensile loading.
  • Elongation: Stainless steel 316 typically exhibits an elongation of approximately 40%. Elongation is the measure of the material’s ability to stretch or deform without fracturing and is expressed as a percentage of the original length.
  • Modulus of Elasticity: The modulus of elasticity, or Young’s modulus, of stainless steel 316 is about 200 GPa (29.0 x 10^6 psi). This property defines the material’s stiffness or resistance to elastic deformation under applied stress.
  • Hardness: Stainless steel 316 typically has a hardness value of around 95 HRB (Rockwell B Hardness). Hardness measures the material’s resistance to indentation or scratching and can vary depending on the specific heat treatment and processing conditions.
  • Impact Resistance: Stainless steel 316 exhibits good impact resistance, allowing it to absorb energy and resist fracture or failure under impact or sudden loading conditions.
