DIN 2445-1 ST52 Hot Finished Seamless Steel Tube for Hydraulic Systems

DIN 2445-1 ST30 ST35 ST45 ST52 Hot Finished Seamless Tubing

Introduction

DIN 2445-1 is a standard that specifies the requirements for hot finished seamless steel tubes used in fluid dynamics systems. These tubes are essential in various applications due to their strength, durability, and resistance to pressure. This article will cover the material specifications, chemical composition, mechanical properties, and applications of ST30, ST35, ST45, and ST52 seamless steel tubes.

Material Specifications

The seamless tubes covered under DIN 2445-1 are produced from carbon steel and are designed to withstand high pressure and temperature conditions. The standard outlines the dimensions, tolerances, and manufacturing processes to ensure the quality and performance of the tubes.

Chemical Composition

The following table presents the typical chemical composition of the materials used in the production of ST30, ST35, ST45, and ST52 seamless steel tubes.

Grade	Carbon (C)	Manganese (Mn)	Phosphorus (P)	Sulfur (S)	Silicon (Si)
ST30	0.12 - 0.20	0.30 - 0.60	≤ 0.035	≤ 0.035	≤ 0.40
ST35	0.15 - 0.25	0.30 - 0.70	≤ 0.035	≤ 0.035	≤ 0.40
ST45	0.20 - 0.30	0.40 - 0.70	≤ 0.035	≤ 0.035	≤ 0.40
ST52	0.22 - 0.30	1.20 - 1.60	≤ 0.025	≤ 0.025	≤ 0.40

Mechanical Properties

The mechanical properties of the seamless tubes are crucial for their performance in fluid dynamics systems. The following table summarizes the key mechanical properties for ST30, ST35, ST45, and ST52 grades.

Grade	Yield Strength (MPa)	Tensile Strength (MPa)	Elongation (%)	Hardness (HB)
ST30	≥ 235	360 - 510	≥ 24	≤ 160
ST35	≥ 275	410 - 550	≥ 22	≤ 170
ST45	≥ 355	490 - 630	≥ 20	≤ 190
ST52	≥ 450	600 - 800	≥ 18	≤ 210

Applications

The seamless steel tubes specified in DIN 2445-1 are widely used in various industries, including:

Hydraulic Systems: For transporting fluids under high pressure.
Pneumatic Systems: Used in applications requiring compressed air.
Oil and Gas Industry: For pipelines and drilling operations.
Automotive Industry: In the manufacturing of components that require high strength and durability.
Construction: For structural applications where seamless tubes are preferred for their integrity and performance.
