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.

St 52.3 350 490-650 18 160

Steel Grade

The steel grades specified in DIN 17121 are designed to meet various structural requirements. Each grade has unique properties that make it suitable for specific applications.

Application

Seamless round tubing under DIN 17121 is widely used in:

  • Construction and structural engineering
  • Machinery and equipment manufacturing
  • Automotive industry
  • Oil and gas pipelines
  • Pressure vessels

Possible Alternative Grades

While the grades specified in DIN 17121 are widely used, there are alternative grades that may be considered based on specific requirements:

  • S235JR: A common structural steel grade with similar properties.
  • S275JR: Offers higher yield strength compared to S235JR.
  • S355JR: Provides even higher strength and is suitable for heavy-duty applications.
