    DIN 17121 RSt 37-2 Seamless Round Tubing Seamless Circular Steel Tubes For Structural Steel Work

    DIN 17121 RSt 37-2 St 37-3 St 44-2 St 44-3 St 52.3 Seamless Round Tubing

    Introduction

    DIN 17121 is a standard that specifies the requirements for seamless circular steel tubes used in structural steel work. This standard covers various steel grades, including RSt 37-2, St 37-3, St 44-2, St 44-3, and St 52.3, each with distinct properties and applications.

    Material Specification

    The seamless round tubing produced under DIN 17121 is primarily made from carbon steel, which is known for its strength and durability. The tubes are manufactured through processes that ensure high quality and reliability for structural applications.

    Key Features

    • Seamless Construction: Provides uniform strength and eliminates weak points.
    • High Strength: Suitable for load-bearing applications.
    • Versatility: Can be used in various structural applications.
    • Corrosion Resistance: Depending on the grade, some tubes may offer enhanced resistance to corrosion.
