What is DIN 2391 ST52 Seamless Precision Steel Tube?

DIN 2391 ST52 is a low-alloy carbon steel grade which is specially designed for use in precision seamless tubing applications. It has excellent mechanical strength combined with superior toughness and is suitable for high performance engineering systems.

With higher yield strength and tensile strength than lower strength grades such as ST35 and ST44, ST52 allows engineers to design lighter and stronger hydraulic and structural components.

The material is frequently supplied in different delivery conditions including:

• BK (Cold Finished Hard)
• BKW (Cold Finished Soft)
• BKS (Stress Relieved)
• GBK (Annealed)
• NBK (Normalized)

The ST52 BK cold drawn seamless precision steel tube is one of the most popular for such applications where dimensional precision and surface quality are of special importance.
