4130 (30CrMo) Steel: A Reliable Partner for Oilfield Drilling Pipes

In the field of oilfield drilling, the performance of materials is the key to determining the quality and stability of drilling pipes. Today, we introduce 4130 (30CrMo) steel. With its excellent performance, it has become a preferred choice for industries such as oilfield drilling and water well drilling.

I. Product Parameters and Performance

Basic Specifications

The specifications of the steel supplied this time are Φ69.85×Φ60.33×3060. It meets the customer's technical requirements and is delivered in the stress - relieved and annealed state.

Precise Chemical Composition

Elements such as C, Si, and Mn are strictly controlled. For example, the C content ranges from 0.28 - 0.33 and the Cr content ranges from 0.80 - 1.10. This ensures the stable basic performance of the material and its adaptability to complex working conditions.

Outstanding Mechanical Properties

It has a tensile strength of more than 800 MPa, a yield strength of more than 720 MPa, and an elongation of more than 15%. The hardness can reach HRC 25 - 28, and the grain size is more than 8.0 grades. It combines high strength - toughness and processing stability. Eddy current inspection, dimensional inspection, and surface quality inspection all meet the standards.

II. Application Scenarios and Advantages

It is suitable for oilfield drilling and water well drilling. Its high strength - toughness can withstand complex stresses. The precise composition and processing technology ensure dimensional stability, reducing the risk of later - stage use, and helping enterprises improve the user experience and durability.

III. Quality Assurance and Service

Strict quality inspection is carried out before delivery. In case of quality problems, you can provide feedback with the material information, and the supplier will respond quickly, providing full - process support for your procurement and use.

Choose 4130 (30CrMo) steel for oilfield drilling pipes to lay a solid material foundation for oil drilling and unleash the performance potential of products!
