Introduction

JIS G 3126 specifies hot-rolled carbon steel plates used in pressure vessels and pressure equipment designed for low-temperature service. These plates are selected for their strength, toughness, and ability to meet specified impact properties under low-temperature operating conditions.

Ladhani Metal Corporation can arrange supply according to customer requirements, subject to grade, dimensions, quantity, and delivery specifications.

Applicable Standard

·        Standard: JIS G 3126:2021

·        Standard title: Carbon Steel Plates for Pressure Vessels for Low Temperature Service

·        Product form: Hot-rolled carbon steel plates

·        Weldable Fine-Grain Steel Plates, where applicable

Scope

JIS G 3126 covers carbon steel plates for pressure vessels and pressure equipment operating at low temperatures. The standard includes requirements for chemical composition, mechanical properties, impact toughness, heat treatment, and dimensional tolerances.

Typical applications include:

·        Low-temperature pressure vessels

·        Liquefied gas storage equipment

·        Industrial tanks and vessels

·        Heat exchangers

·        Petrochemical processing equipment

·        Gas processing and refrigeration equipment

·        Low-temperature pressure-containing structures

Chemical Composition

Chemical composition is controlled to achieve suitable strength, weldability, and toughness at low temperatures. The following values are general reference limits for the JIS G 3126 grade family. Exact requirements vary by grade and thickness and must be confirmed against the applicable standard edition.

Note: The table is a general reference and does not replace the full grade-by-grade requirements of JIS G 3126:2021. Additional requirements for carbon equivalent or weld-crack sensitivity composition may apply, particularly to plates produced by thermo-mechanical controlled processing.

Mechanical Properties

Mechanical properties depend on grade, plate thickness, heat treatment, and test-piece requirements. The following table provides general reference values.

Low-temperature Charpy impact requirements differ by grade and test temperature. The exact elongation, impact energy, and applicable thickness limits must be confirmed before engineering use.
