If you are looking for high-quality precision ground 316 stainless steel rods, Gnee offers a wide range of rods designed for applications requiring tight tolerances, superior corrosion resistance, and excellent mechanical properties. Our rods are used across industries including aerospace, medical, marine, chemical processing, and precision engineering.
What Is Precision Ground 316 Stainless Steel Rod?
Precision ground 316 stainless steel rod is a high-performance austenitic stainless steel bar that has been machined and ground to tight dimensional tolerances (commonly ±0.01 mm). The process produces a smooth surface finish, making it ideal for applications requiring exact fits, high surface quality, and minimal post-processing.

How to calculate SS316 rod weight?
Where:
D = rod diameter in meters
ρ = stainless steel density (~8000 kg/m³)
Example: 20 mm diameter rod: Weight=3.1416×(0.022/4)×8000≈2.51kg/m
Can 316 rods be used in high-speed fluid environments?
Yes, precision ground 316 rods are often used as shafts, pins, or guide rods in pumps and flow systems. The smooth finish ensures minimal friction and stable performance under turbulent flow.
Is 316 rod suitable for high-temperature applications?
Yes. 316 stainless steel can withstand continuous use up to 870°C, and short-term peaks up to 925°C.
