SGV410 Boiler Steel Plate is a Japanese standard steel plate used in the manufacture of boilers and pressure vessels. It is widely used in industries such as petroleum, chemical engineering, power plants, and boiler systems. The steel plate is primarily used to produce reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, boiler drums, LPG cylinders, high-pressure water pipes for hydropower stations, turbine volutes, and other critical equipment and components.

SGV410 Steel Plate Overview

Standard: JIS G3118

SGV410 is designed for boiler and pressure vessel applications. It is mainly used in the petroleum, chemical, power plant, and boiler industries.

for Steel SGV410 (JIS ) and its European equivalent P235GH (1.0345) ( EN )

Delivery Condition of SGV410 medium And low strength pressure vessel plate:

Plates with Thickness ≤ 38mm:
Generally delivered in the hot-rolled state, but can be normalized if required.

Plates with Thickness > 38mm:
Should undergo tempering or hot-forming with pressure to achieve a proper crystal grain size.

Plates with Thickness < 100mm:
To improve thermal properties or enhance weldability, these plates can also undergo hot processing control as needed.

Production Process for SGV410 Steel Plate:

Raw Material Preparation:
Includes the use of scrap steel, pig iron, and molten iron.

Electric Arc Furnace (EAF) Smelting:
Steel is smelted in an electric arc furnace.

Basic Oxygen Furnace (BOF) Treatment:
Steel is processed in a BOF for further refinement.

LF Furnace Steel Refining:
Steel undergoes further refining in the LF furnace.

Vacuum Treatment (VD/VOD):
Steel is treated in a vacuum or VOD furnace to reduce impurities.

Heating and Rolling:
The steel is heated and then rolled into plate form.

Heat Treatment (Normalizing, Tempering):
Steel is normalized or tempered to achieve the required mechanical properties.

Cutting, Inspection, and Warehousing:
After rolling and heat treatment, the steel plates are cut, inspected, and stored.

Shape, Size, Weight, and Tolerances:

The shape, size, weight, and allowable tolerances of SGV410 steel plates are in compliance with JIS G 3193.

The allowable tolerances for plate length and cut edge width are governed by special provisions outside of the standard.

Application Range:

SGV410 steel plates are primarily used in the manufacture of pressure vessels and storage tanks, including:

Spherical storage tanks with a capacity of over 50 cubic meters.

Single-layer welded containers, multi-layer thermal jacket welded containers, and multi-layer wrapped containers.

Low-temperature pressure vessels.

The steel is commonly used in critical components for industries such as:

Petroleum

Chemical

Power generation

Boilers

Typical applications include:

Reactors

Heat exchangers

Separators

Spherical tanks

Oil and gas tanks

Liquefied gas tanks

Boiler drums

LPG cylinders

High-pressure water pipes for hydropower stations

Turbine volutes and other related equipment.
