Important Tips about Purchasing Stainless Steel Angle Bars

The stainless steel angle bar has been popular in construction industry for decades. Many people may not know it very well as it’s only ordinary plain building material without any shining or gorgeous appearance which can catch attentions. But beyond doubt, stainless steel angle bar is very important, actually, it helps to build our fancy modern life.  

This article with give you a exhaustive introduction of stainless steel angle bars. These information and tips will also help you to pick out and purchase qualified stainless steel angle bars

1.The Categories and Specifications of Stainless Steel Angle Bar

The stainless steel angle bar is a kind of strip steel whose two arms are perpendicular to each other and form a right angle, and is generally made of low-carbon square steel billets. There are two main types of stainless steel angle bar: equilateral stainless steel angle bar and scalene stainless steel angle bar. The two sides of an equilateral stainless steel angle bar have the same width. Scalene stainless steel angle bars are mainly created to widen the applied range of stainless steel angle bars, and can be further divided by its thickness. In practical application, the specific selection of width and thickness depend on the application scenarios.

From the perspective of original materials, austenitic stainless steel angle bar is the most used one. The properties of martensitic stainless steel angle bar and PH stainless steel angle bar are relatively special. The former has high strength and hardness, whose properties can be adjusted by means of heat treatment. The strength of the latter can be enhanced by precipitating the internal carbide.

The specification of stainless steel angle bar is expressed as “width· width· thickness” , such as "∠25·25·3" , whose units is millimeters. It can also be expressed as model, such as “∠3#” , whose unit is the centimeters of width. It’s worth noting that the model cannot reflect the thickness of stainless steel angle bar, you still need to fill it clearly in the contract and other documents.

2.Application Scenarios

Stainless steel angle bars are mainly used to make frame structure buildings. They are widely used in urban landscape, advertising and decoration project, industrial production, etc. They participates in many large construction works, such as power transmission towers, frames on the side of the main girders of steel structure Bridges, the columns and arms of tower cranes and the beams and machines of factories. Actually, stainless steel angle bars is also inseparable to our daily, you can see them almost everywhere. They are usually made into billboards, air conditioning bracket, and interiors decorations in the mall.

Although stainless steel angle bars are not eye-catching things, they are still very important for the glamorous modern society and provides many conveniences for our life.

                             

3.Effective standards to Evaluate Quality of Stainless Steel Angle Bars

——From the perspective of physical properties：

The stainless steel angle bar is one of rolled steels for general structure. The main test indicators of elements are carbon, manganese, phosphorus and sulphur, whose specific standard content is according to the different model specification. The weldability, plastic deformation property and mechanical strength are also important detection index, which can be judged by the data of the tensile test and bending test, whose main indicators include yield point, tensile strength, elongation and bending eligibility.

——From the perspective of forms and appearance

Stainless steel angle bars should not have obvious layering, scarring, cracks or other defect affecting further uses. Surface quality and geometric deviation of stainless steel angle bar should be detected in advance. The specific permissible range should refer to the corresponding normative documents. The reference values generally include bending degree, width, thickness, theoretical weight and so on. It is also important that the stainless steel angle bar should not have obvious torsion.

The quality and characteristics of stainless steel angle bars play a key role in the production process and may even affect the degree of safety. You need to pay special attention to the qualification of supplier when purchasing as these things is difficult to judge only by the naked eye. It is also necessary to check the product quality testing reports and choose the company which roots in the industry for many years and has rich production experience and good reputation.
