Common materials for 12.9 threaded rod include stainless steel 12.9 threaded rod, tool steel, chromium-cobalt-molybdenum alloy steel, polyimide and polyamide.
Characteristics of different materials for strongest threaded rod
Stainless steel threaded rod: Stainless steel lead screws are widely used in chemical, aviation, metallurgy and other industries due to their excellent corrosion resistance, high strength and rigidity.
Tool steel threaded rod: Such as SKD11, it has extremely high hardness and wear resistance, and is suitable for transmission applications requiring extremely high precision and high load.
Chromium-cobalt-molybdenum alloy steel threaded rod: Such as SCM420H, it has high strength, high hardness and good wear resistance, and is suitable for transmission applications with high precision and high load.
Polyimide threaded rod: It has excellent high temperature resistance and chemical corrosion resistance, and is suitable for aerospace, aviation and other fields.
Polyamide threaded rod: It has high viscous damping performance and shock absorption performance, and is suitable for metallurgy, petroleum and other fields.
Applicable scenarios of class 12.9 threaded rod of different materials
Stainless steel threaded rod 12.9: Suitable for highly corrosive environments such as chemical and marine.
Tool steel threaded rod 12.9: Suitable for transmission applications requiring extremely high precision and high loads.
Chromium-cobalt-molybdenum alloy steel: Suitable for high-precision and high-load machine tools and CNC machine tools.

Processing technology and surface treatment of different materials for b12 threaded rod
Stainless Steel 12.9 grade bolts: Usually undergoes appropriate heat treatment, such as quenching and tempering, to increase its hardness and strength.
Tool steel: After heat treatment, the hardness can reach above HRC 60.
Chromium-cobalt-molybdenum alloy steel: After heat treatment, the hardness can reach HRC 58-62.
Polyimide: Usually does not require heat treatment, but its manufacturing process requires strict control of temperature and pressure.
Polyamide: Usually does not require special heat treatment, but the humidity and temperature during processing do need to be controlled.
By selecting appropriate materials and reasonable processing technology, the performance and service life of high-precision screws can be significantly improved.
