JIS G3462 STBA12 Alloy Steel Tube For Boiler And Heat Exchanger Tubes 0

JIS G3462 STBA12, STBA13, STBA20, STBA22, STBA23 Alloy Steel Tube for Boiler and Heat Exchanger

Material Specification

JIS G3462 is a Japanese industrial standard that specifies alloy steel tubes used for boilers and heat exchangers. These tubes are designed to withstand high temperatures and pressures, making them ideal for use in power plants, chemical plants, and other industrial applications. The grades STBA12, STBA13, STBA20, STBA22, and STBA23 are among the most commonly used in this standard.

Key Features

High Temperature Resistance: These alloy steel tubes are designed to perform efficiently under high-temperature conditions.
Corrosion Resistance: The alloy composition provides excellent resistance to corrosion, extending the lifespan of the tubes.
Mechanical Strength: The tubes offer superior mechanical properties, ensuring durability and reliability in demanding environments.
Versatility: Suitable for a wide range of applications, including boilers and heat exchangers in various industries.

Chemical Composition

The chemical composition of these alloy steel grades is crucial for their performance. Below is a table detailing the typical chemical composition for each grade:

Element	STBA12	STBA13	STBA20	STBA22	STBA23
Carbon (C)	0.15 max	0.15 max	0.15 max	0.15 max	0.15 max
Silicon (Si)	0.50 max	0.50 max	0.50 max	0.50 max	0.50 max
Manganese (Mn)	0.30-0.60	0.30-0.60	0.30-0.60	0.30-0.60	0.30-0.60
Phosphorus (P)	0.035 max	0.035 max	0.035 max	0.035 max	0.035 max
Sulfur (S)	0.035 max	0.035 max	0.035 max	0.035 max	0.035 max
Chromium (Cr)	0.50-1.00	0.50-1.00	0.50-1.00	0.50-1.00	0.50-1.00
Molybdenum (Mo)	0.45-0.65	0.45-0.65	0.45-0.65	0.45-0.65	0.45-0.65

Mechanical Properties

The mechanical properties of these tubes are critical for their performance in high-pressure and high-temperature environments. The table below outlines the typical mechanical properties:

Property	STBA12	STBA13	STBA20	STBA22	STBA23
Tensile Strength (MPa)	≥ 415	≥ 415	≥ 415	≥ 415	≥ 415
Yield Strength (MPa)	≥ 205	≥ 205	≥ 205	≥ 205	≥ 205
Elongation (%)	≥ 30	≥ 30	≥ 30	≥ 30	≥ 30

Steel Grade

The steel grades STBA12, STBA13, STBA20, STBA22, and STBA23 are part of the JIS G3462 standard, each offering specific properties tailored for different applications. These grades are selected based on the specific requirements of the application, such as temperature, pressure, and environmental conditions.

Application

These alloy steel tubes are primarily used in:

Boilers: For generating steam and hot water in power plants and industrial facilities.
Heat Exchangers: For transferring heat between fluids in chemical plants, refineries, and other industrial processes.
Petrochemical Industry: For processing and transporting chemicals and fuels.
Power Generation: In turbines and other equipment where high-temperature resistance is crucial.

Possible Alternative Grades

While JIS G3462 grades are widely used, there are alternative grades that may be considered based on specific requirements:

ASTM A213: A similar standard for seamless ferritic and austenitic alloy steel boiler, superheater, and heat-exchanger tubes.
EN 10216-2: A European standard for seamless steel tubes for pressure purposes, with a focus on high-temperature applications.
DIN 17175: A German standard for seamless tubes of heat-resistant steels.
