In this article, we will discuss in detail what DIN2391 St37.4 NBK is, its benefits, and how it can help boost efficiency.

What is DIN2391 St37.4 NBK?

DIN2391 St37.4 NBK is a type of precision seamless steel tube that is widely used in various industries for its excellent mechanical properties and metallographic structure. Let’s take a closer look at what DIN2391 St37.4 NBK means and its specific characteristics.

Definition of DIN2391 St37.4 NBK

DIN2391 St37.4 NBK is a specific type of precision seamless steel tube. DIN2391 is the standard for seamless precision steel tubes, while St37.4 is the steel grade. NBK stands for “normalizing annealing, bright annealing, and non-destructive testing.”

NBK Process

The NBK process is a heat treatment process used to enhance the mechanical properties of steel tubes. During the NBK process, the seamless steel tube is normalized under a controlled atmosphere.

Then, it is annealed using a bright heat treatment process, where ammonia-decomposed nitrogen and hydrogen are injected for protection heating, heat preservation, and cooling.

This process maintains the original rolling accuracy and smoothness of the steel tube and results in an excellent mechanical structure and properties.

Surface Treatment

In addition to the NBK process, DIN2391 St37.4 NBK undergoes a surface treatment process called phosphating. This process involves the application of a phosphate coating to the inner and outer walls of the steel tube.

The phosphate coating creates a uniform and dense crystal structure that provides excellent corrosion resistance, making it ideal for use in harsh environments.

DIN2391 St37.4 NBK is a precision seamless steel tube that undergoes a unique heat treatment process and surface treatment process, resulting in excellent mechanical properties, corrosion resistance, and anti-rust properties.
