JIS G3466 STKR400 Structural Steel Pipe: Carbon Steel Square and Rectangular Tubes for General Structure

Introduction

JIS G3466 STKR400 is a standard specification for carbon steel square and rectangular tubes used in general structural applications. These tubes are known for their excellent mechanical properties and versatility, making them suitable for various construction and engineering projects.

Material

The material used in the production of STKR400 tubes is carbon steel, which provides a good balance of strength, ductility, and weldability. This makes it an ideal choice for structural applications where durability and performance are critical.

Specification

The specification outlines the requirements for the manufacturing and testing of the steel tubes, ensuring they meet the necessary standards for structural integrity and performance.

Key Features

High Strength: STKR400 offers excellent tensile strength, making it suitable for load-bearing applications.
Versatility: Available in various sizes and shapes, it can be used in a wide range of applications.
Weldability: The carbon steel composition allows for easy welding, facilitating construction processes.
Corrosion Resistance: While not inherently corrosion-resistant, appropriate coatings can enhance its durability in various environments.

Chemical Composition

Element	Composition (%)
Carbon (C)	0.20 - 0.25
Manganese (Mn)	0.30 - 0.60
Phosphorus (P)	≤ 0.035
Sulfur (S)	≤ 0.025
Silicon (Si)	≤ 0.40
Iron (Fe)	Balance

Mechanical Properties

Property	Value
Yield Strength (MPa)	≥ 245
Tensile Strength (MPa)	400 - 510
Elongation (%)	≥ 20
Hardness (HB)	≤ 150

Steel Grade

The STKR400 grade is specifically designed for structural applications, providing a reliable option for engineers and architects in their designs.

Application

STKR400 tubes are widely used in various applications, including:

Construction of buildings and bridges
Manufacturing of furniture and fixtures
Automotive and transportation components
General engineering and fabrication projects

Possible Alternative Grades

While STKR400 is a popular choice, there are alternative grades that may be considered based on specific requirements:

STKR50: A lower strength grade suitable for lighter applications.
STKR60: Offers higher strength for more demanding structural needs.
S235JR: A European equivalent that provides similar mechanical properties.
