Common Classification and Application of Stainless Steel Angle Bar

Written by

Stainless steel angle bar is a kind of widely used stainless steel section, which has the characteristics of structural stability, corrosion resistance, strong resistance to deformation and stability of chemical properties. It has an incomparable advantage over other metal materials.

Name definition of stainless steel angle bar

Stainless steel Angle is commonly referred to stainless steel material, the long strip of steel that is rectangular on each side. The length of the bar is divided into equal sides stainless steel angles and stainless steel angles. The two sides are equal to the stainless steel angles.

The stainless steel angle bar is made of stainless steel

Stainless steel angles can be classified according to the material, common for markov size stainless steel, iron, stainless steel, duplex stainless steel, austenite stainless steel and precipitation hardening stainless steel, and so on.

Austenitic stainless steel

The output and quantity of this kind of material occupies the mainstream position of the product, accounting for 70.1 percent of the total stainless steel. It’s a very important category in stainless steel. The austenitic stainless steel can be divided into two types: chromium nickel steel and ferrochrome. The former is an austenitic element with nickel, which is the main body of austenitic steel, which takes into account the cost of production, the latter is a nickel steel which is used as a nickel for manganese and nitrogen instead of expensive nickel. Good corrosion resistance of austenitic steel, good integrated mechanical properties and technical performance, but weak strength and hardness.

Iron is stainless steel

Iron-clad stainless steel contains 31-30%, which is non-nickel and is a nickel steel, which is mainly made of ferrite in the state of use. Iron grain size stainless steel has higher strength and lower cold hardening tendency, resistance to chloride stress corrosion, pit corrosion, crevice corrosion and local corrosion performance is good, but is sensitive to intergranular corrosion, poor toughness at low temperature.

Duplex stainless steel

Traditional thought, on the austenitic matrix is more than 15% of the ferrite, on the other hand, there is more than 15% of the ferrite matrix we can call austenitic austenitic + ferrite duplex stainless steel. Duplex stainless steel has the advantages of austenitic steel and ferritic steel.

These are common materials for making stainless steel angles. In addition, the above materials are also widely used in other forms of form, plates, pipes and so on.

Description of common stainless steel angle bar

Size notation

When we see this statement, “30 by 30 * 3”, which means that the edge width is 30 mm, the side thickness is 3mm, the stainless steel angle bar. This is the number of millimeters in the width of the side width by side.

Figure 2

The model is the width of a centimeter, such as Angle 3 #. Model cannot express the same edge thickness in different circumstance of product information, and therefore the buyer and the seller at the time of custom contract, still need to fill in the width, and thickness of the stainless steel Angle bar size is complete, rather than separate with that model, in order to avoid ambiguity, caused the dispute.

At present, the common domestic stainless steel angle bar specification is 2 to 20, with the centimeter number of the side length is number, the same number of angle bar is about 2 to 7 different sides thick. The import stainless steel Angle indicates the actual size and thickness of each side and the relevant standard. Generally large stainless steel Angle bar length more than 12.5 cm, 12.5 cm, 5 cm as the medium between the stainless steel Angle, less than 5 cm length for small stainless steel angle.

The delivery length of stainless steel angle bar

In addition to the thickness of the stainless steel, the product is also required to order the product according to the length. To meet the needs of different application scenarios. Stainless steel bar length, length of delivery points two times ruler, domestic stainless steel Angle iron scale range according to different size specifications have 3 to 9 m, 4 m, 4-12-19 m, 6 – m four range. The length of Japanese stainless steel angle bar is 6-15m. The section height of stainless steel angle bar is calculated by the long side width of stainless steel angle bar.

Stainless steel angle bar appearance quality requirement

Stainless steel Angle should not be used for harmful defects such as layering, scarring and cracks. Surface quality has specific provisions in the standard, stainless steel Angle geometry deviation allowed range also has stipulated in the standard, generally including bending, thick, apex Angle and width, while theoretical weight, etc, and stainless steel Angle, stainless steel Angle shall not have a significant twist.

Common use of stainless steel angle bar

Stainless steel angle bar is widely used in various building structure and engineering structure, from the civilian beams, and warehouse shelves, equipment frame base, to industrial Bridges, transmission tower, lifting transportation machinery and even military ship, industrial furnace, reaction tower, container frame. Different force components can be composed of different structures, which can also be used as the connecting parts between the components.

Stainless steel angle bar, for example, is comparable to other materials, such as Angle iron. But the cost is higher, not all applicable occasions will be built with the steel Angle of the stainless steel.

Appendix: the material and specifications of stainless steel angle bar

Stainless steel angle bar spot material: 201, 202, 301, 202, 301 (0 cr18ni9), 304 l (00 cr19ni10), 316 (0 cr17ni12mo2), 316 l (00 cr17ni14mo2), 309 s (0 cr23ni13), 310 s (0 cr25ni20), 321 (1 cr18ni9ti), 410 s (1 cr13), 420 j1 (2 cr13), 430 (1 cr17), 317, 347, 403, 405, 403 l.
