Application Focus

Machine Components

Creating a wear-resistant, high-lubricity surface to prevent dimensional loss and maintain strict tolerance limits over millions of cycles.

The Challenge and Solutions

Machine components rarely operate in a vacuum; they interact with other materials, lubricants, and harsh ambient conditions. Whether it is a lead screw losing its smooth motion or a shaft succumbing to premature bearing failure, these challenges impact output efficiency.

Shital Plasma Nitriding addresses these mechanical challenges by creating a wear-resistant, high-lubricity surface that maintains tolerance limits over millions of cycles.

How We Solve Machine Component Challenges

Problem Faced Mechanism of Plasma Nitriding Solution
Scratch Mark Increases surface hardness and reduces the coefficient of friction, preventing surface damage from particle debris or metal-to-metal contact.
Wear & Tear Forms a hardened diffusion layer that effectively resists abrasive and adhesive wear, protecting the component from dimensional loss during continuous operation.
Corrosion of Components Provides a robust metallurgical barrier that resists oxidation and environmental chemical attacks, critical for machinery operating in humid or non-cleanroom environments.

Material Specifications for Machine Components

Machine components are often constructed from low-to-medium alloy steels. Plasma nitriding allows these cost-effective materials to achieve surface performance comparable to expensive, through-hardened alloys. The specifications below are standard for industrial machine parts requiring high reliability.

Material / Grade Application Area Target Surface Hardness Recommended Case Depth
AISI 4140 / 4340 Shafts, Gears & Axles 600 – 750 HV 0.20 – 0.40 mm
AISI 8620 Case-Hardened Gears 700 – 850 HV 0.25 – 0.50 mm
Cast Iron Cast Iron Body 450 – 800 HV 0.05 – 0.10 mm
Low Alloy Steels - 16MnCr5 / 20MnCr5 Components 600 – 700 HV 0.10 – 0.25 mm
MS / C45 / En8 Components 300 – 450 HV 0.05 – 0.10 mm
En19 / En24 Components 600 – 800 HV 0.10 – 0.30 mm
Mild / Carbon Steel General Machine Brackets 550 – 700 HV 0.25 – 0.50 mm
Stainless Steel 300 & 400 Series / Duplex Corrosion-Resistant Sleeves 900 – 1050 HV 0.10 – 0.20 mm
Note: For general machine components, we focus on a deep, stable diffusion zone. This ensures that even if the component is subject to occasional regrinding or light machining during its service life, the hardened performance layer remains intact.
