Product Description

Product Description

 

Introduction

LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
 

Nitriding 135 Steel is a modification of AISI 4140 designed specifically for nitriding applications. As a chrome-moly alloy steel with the addition of aluminum, Nitriding 135 is well-suited for components requiring high surface hardness, heat resistance, and dimensional stability.

Typically supplied in a pre-hardened condition with a hardness of 26-30 HRC, Nitriding 135 Steel is ready for nitriding without the need for further heat treatment. If higher core strength is required, additional heat treatment can be applied. The alloy retains its case and core properties at temperatures up to 1000°F and shows minimal distortion during heat treatment, making it an excellent choice for applications that demand precision and durability.

Nitriding 135 Steel Applications

• Automotive Components: Used in parts such as gears and shafts that require high surface hardness and dimensional stability after nitriding.
• Aerospace Components: Suitable for aerospace applications where wear resistance and heat resistance are critical.
• Industrial Machinery: Ideal for machinery components that undergo nitriding to enhance surface hardness and performance in high-stress environments.
• Precision Engineering: Applied in components that require minimal distortion during heat treatment, such as molds and dies.

Features of Nitriding 135 Steel:

• Modification of AISI 4140: A specially modified version of AISI 4140, with the addition of aluminum, designed for nitriding applications.
• Chrome-Moly Alloy: Contains chromium and molybdenum, providing a balance of strength, heat resistance, and wear resistance.
• Pre-Hardened: Ready for nitriding in its pre-hardened condition, offering excellent machinability and reducing manufacturing time.
• Heat Resistance and Dimensional Stability: Retains both surface hardness and core strength at elevated temperatures, with minimal distortion during heat treatment.
• Versatile: Suitable for a wide range of applications, from automotive components to aerospace parts and industrial machinery.
