What is Stainless Steel Angle Steel?
Stainless steel angle, commonly known as stainless steel angle iron, is a long strip of steel with two sides perpendicular to each other into an angle. There are equilateral stainless steel angles and unequal stainless steel angles. Among them, unequal-side stainless steel angles can be divided into unequal sides, equal thickness, and unequal sides, unequal thickness. The section height of the unequal side stainless steel angle steel is calculated according to the long side width of the unequal side stainless steel angle steel.
Stainless steel angle steel can be composed of various stress-bearing components according to the different needs of the structure, and can also be used as a connection between components. It is widely used in various building structures and engineering structures, such as house beams, bridges, power transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves.
Stainless steel angle steel is a simple cross-section steel made of stainless steel material. It is mainly used for metal components and the frame of the factory building. In use, it requires good weldability, plastic deformation performance, and certain mechanical strength. The raw material billets for the production of stainless steel angles are stainless steel square billets, and the finished stainless steel angles are delivered in a hot-rolled, normalized, or hot-rolled state.
Specification of Stainless Steel Angle
- Equal angle steel: The width of both sides is the same, often used for structural support.
- Unequal angle steel: The width of both sides is different, suitable for special design requirements.
The two side widths of equilateral stainless steel angles are equal. Its specifications are expressed in millimeters of side width×side width×side thickness. For example, “∠25×25×3” means an equilateral stainless steel angle with a side width of 30 mm and a side thickness of 3 mm. It can also be expressed by model number, which is the number of centimeters of the side width, such as ∠3#.
The model number does not indicate the dimensions of different side thicknesses in the same model. Therefore, fill in the side width and side thickness dimensions of the stainless steel angle steel in the contract and other documents, and avoid using the model number alone. The specification of hot-rolled equilateral stainless steel angle steel is 2#-20#.
The dimensions of side length and side thickness express the specification of stainless steel angle steel. Currently, the domestic stainless steel angle steel specifications are 2-20, and the number of centimeters on the side length is used as the number. The stainless steel angle steel of the same number often has 2-7 different side thicknesses.
Imported stainless steel angles indicate both sides’ actual size and thickness and the relevant standards. Generally, those with a side length of 12.5cm or more are large stainless steel angles, those with a side length between 12.5cm and 5cm are medium-sized stainless steel angles, and those with a side length of 5cm or less are small stainless steel angles.
The order of import and export angle steel is generally based on the specifications required in use, and the steel grade is the corresponding stainless steel grade. That is to say, the angle steel has no specific composition and performance series except for the specification number.
Stainless Steel Angle Steel Appearance Quality Requirements
The surface quality of stainless steel angle steel is stipulated in the standard, and it is generally required that there should be no harmful defects in use, such as delamination, scarring, and cracks.
Unequal angle steel—The allowable range of geometric shape deviation of stainless steel angle steel produced by Yancheng Baojun Stainless Steel Co., Ltd. is also specified in the standard, which generally includes items such as curvature, side width, side thickness, top angle, and theoretical weight, and It is stipulated that the stainless steel angle steel shall not be significantly twisted.
The main advantages of stainless steel angle steel
Strong corrosion resistance: Stainless steel angle steel can maintain good performance in corrosive environments such as moisture, acidity, and alkalinity due to the oxide film on its surface.
High strength: Stainless steel angle steel has excellent mechanical strength and can withstand large weight and pressure.
Good plasticity: Stainless steel angle steel is easy to process, cut, and weld, so it is suitable for a variety of construction and industrial scenarios.
High-temperature resistance: Some stainless steel angle steels also have good high-temperature resistance and can maintain stability in high-temperature environments.
Application of Stainless Steel Angle Steel
Construction industry: frame structures and support beams used in buildings.
Industrial equipment: such as chemical equipment, food processing equipment, offshore platform structures, etc.
Home decoration: Stainless steel angle steel is also used in home designs such as stair handrails and decorative frames.
Machinery manufacturing: When manufacturing machinery and equipment, stainless steel angle steel is often used for important components such as brackets and frames.
What is the ASTM Standard for Stainless Steel Angles?
1. ASTM A276
The ASTM A276 standard specifies the production requirements for stainless steel profiles and applies to hot-rolled and cold-drawn stainless steel bars and profiles, including angles. The standard specifies the chemical composition, mechanical properties, dimensional tolerances, and other requirements for different types of stainless steel.
2. ASTM A484
ASTM A484 is a general standard for stainless steel products, including the size, appearance, and surface quality requirements of formed stainless steel angles, as well as the testing and acceptance conditions of stainless steel products during the production process.
3. ASTM A240
ASTM A240 applies to the production of stainless steel plates and strips. Although this is not a standard directly applicable to angles, many times the material of stainless steel angles is derived from plates produced under these standards. Therefore, the requirements of A240 are of reference value for determining the chemical composition and mechanical properties of the material.
4. ASTM A484/A484M
This standard guides the dimensional tolerance and tolerance control of stainless steel angles and other stainless steel products to ensure consistency and reliability in manufacturing and use.
Commonly used stainless steel angle steel types and materials:
- 304 stainless steel angle steel: meets ASTM A276 standard, commonly used in general structures and light industrial applications, and widely used due to its good corrosion resistance.
- 316 stainless steel angle steel: meets ASTM A276 standard, and has stronger corrosion resistance, especially in acidic and marine environments.
Huaxiao Metal provides stainless steel angles that meet ASTM standards and provide customers with high-quality products and professional technical support. Welcome to consult for more information.
How to Choose the Right Stainless Steel Angle Steel?
When choosing stainless steel angle steel, its material, size, and surface treatment should be considered according to the actual application scenario.
Material: Common stainless steel angles are 201, 304, 316, etc. 304 stainless steel angles are the most common due to their superior corrosion resistance and wide application.
Size: The appropriate size should be selected according to the specific load-bearing requirements.
Surface treatment: The surface can be brushed, polished, etc. to increase the aesthetics or corrosion resistance.
