Stainless Steel Angle Bar Classification and Applications

The stainless steel angle bar is a widely used type of stainless steel with features such as stable structure, corrosion resistance, strong resistance to deformation, and stable chemical performance. Compared to other metal profiles, it has unparalleled advantages. In this article, let’s take a close look at stainless steel angle bar classification and applications.

Definition of Stainless Steel Angle Bar

A stainless steel angel bar generally refers to a long strip of stainless steel with two right angles. It is divided into equal-side stainless steel angel bars and unequal-side stainless steel angel bars according to the length of the edges. The one with equal edges is an equal-side stainless steel angel bar.

Stainless Steel Angle Bar Classification

Stainless steel angle bars can be classified according to their materials, including martensitic stainless steel, ferritic stainless steel, duplex stainless steel, austenitic stainless steel, precipitation-hardened stainless steel, and so on.

Stainless Steel Angle Bar Classification – Austenitic Stainless Steel

Austenitic stainless steel is a very important category of stainless steel, accounting for 70.1% of the total volume. It can be divided into two major categories: chromium-nickel steel and iron-chromium-manganese steel, with the former using nickel as the austenitizing element and the latter using manganese and nitrogen as cost-effective alternatives to nickel. Austenitic stainless steel has good corrosion resistance, comprehensive mechanical properties, and processability, but its strength and hardness are relatively weak.

Stainless Steel Angle Bar Classification – Ferritic Stainless Steel

Ferritic stainless steel contains 11%-30% chromium and is almost nickel-free, making it a cost-effective alternative to nickel-containing stainless steel. It has high strength and low tendency for cold-working hardening and is resistant to chloride stress corrosion, pitting, crevice corrosion, and other forms of local corrosion. However, it is sensitive to intergranular corrosion and has poor low-temperature toughness.

Stainless Steel Angle Bar Classification – Dual-phase Stainless Steel

Dual-phase stainless steel is traditionally considered to have more than 15% ferrite in an austenitic matrix, and vice versa, if there is more than 15% austenite in a ferrite matrix, it can be referred to as austenite-ferrite dual-phase stainless steel. Dual-phase stainless steel combines the advantages of austenitic steel and ferritic steel.

Stainless Steel Angle Bar Classification – Martensitic Stainless Steel

Martensitic stainless steel is a type of steel that can be adjusted in performance through heat treatment, with high strength and hardness. Precipitation-hardening stainless steel is a type of steel that achieves strength improvement through heat treatment, causing precipitation of carbides in the steel.

Stainless Steel Angle Bar Applications

Stainless steel angle bars are widely used in various building and engineering structures, ranging from residential beams, warehouse racks, equipment, and machine frame bases, to industrial bridges, transmission towers, lifting and transportation machinery, even military ships, industrial furnaces, reactors, and container frames. They can be composed of various stress components according to the different needs of the structure, and can also be used as connecting components between components.

Compared with angle bars made of other materials (such as angle iron), stainless steel angle bars have unparalleled material performance. However, due to the high cost, they are not always used in construction for all applicable situations.
