30CrMo Round Steel Bar Description

30CrMo round steel bar is a high-quality alloy steel material with unique characteristics such as high strength, wear resistance, and corrosion resistance. The "30" represents a carbon content of approximately 0.3% (or 30‰), and Cr and Mo represent the elements of chromium and molybdenum contained in the steel, respectively. 30CrMo round br is suitable for manufacturing high-pressure vessels, high-pressure chemical equipment, forging, oil extraction, and other mechanical equipment.

The 30CrMo alloy steel round bar has the following characteristics:

1. High strength: 30CrMo round steel has excellent tensile strength and impact resistance, capable of withstanding high stress and load.

2. Wear resistance: This steel adopts a professional alloy blending process, which can effectively resist wear and corrosion and extend the service life.

3. Corrosion resistance: 30CrMo round steel has good corrosion resistance and can maintain its stable performance in humid and corrosive environments.
