Exploring 35CrMo Steel Properties, Applications, and Manufacturing Factories

35CrMo steel is a high-strength alloy steel that is widely utilized in various industrial applications due to its exceptional mechanical properties and versatility. This article delves into the characteristics of 35CrMo steel, its applications in various sectors, and the manufacturing processes carried out by factories specializing in the production of this alloy.

Understanding 35CrMo Steel

The designation 35CrMo refers to a specific alloy composition of carbon (C), chromium (Cr), and molybdenum (Mo). The numbers in the name indicate the approximate carbon content (0.35%) and the fortifying elements. 35CrMo steel is part of the 30CrMo series, generally recognized for its high tensile strength, wear resistance, and toughening characteristics. This alloy typically contains around 0.30-0.40% carbon, 0.90-1.20% chromium, and 0.15-0.25% molybdenum, which contribute to its excellent mechanical properties.

Mechanical Properties

One of the standout features of 35CrMo steel is its excellent strength-to-weight ratio. The hardening processes it undergoes, such as quenching and tempering, enhance its hardness and yield strength. Typical mechanical properties of 35CrMo steel include

- Tensile Strength Can reach up to 1100 MPa after proper heat treatment. - Yield Strength Generally falls within 800-1000 MPa. - Elongation Approximately 12-14%, demonstrating good ductility. - Impact Toughness Offers resistance to fracture under impact, making it suitable for high-stress environments.

These properties make 35CrMo steel suitable for components that require high strength and wear resistance, such as shafts, axles, and structural elements.
