1、 Definition and application scope of stainless steel square steel

Stainless steel square steel is a square steel made of stainless steel material. Stainless steel square steel is widely used in fields such as construction, automobiles, ships, chemicals, and electricity, and is an excellent structural material.

2、 Standard for stainless steel square steel

There are detailed regulations for the standards of stainless steel square steel both domestically and internationally. The following are common standards for stainless steel square steel both domestically and internationally:

1. Domestic standards: The Chinese national standards GB/T 14975-2002 and GB/T 14976-2002 respectively specify the requirements for the outer diameter and wall thickness, surface quality, mechanical properties, etc. of stainless steel square steel.

2. American standard: The American ASTM A276/A276M-17a standard specifies the requirements for chemical composition, mechanical properties, processing technology, surface condition, and other aspects of stainless steel square steel.

3. European standard: The European standard EN 10088-3-2005 specifies various indicators such as chemical composition, mechanical properties, processing technology, and surface condition of stainless steel square steel.

3、 Differences between different standards

Although there are slight differences in the requirements for stainless steel square steel standards formulated by different countries, there are still some significant differences overall. As follows:

1. Chemical composition requirements: European standards have relatively strict requirements for chemical composition, while American standards have relatively loose requirements for chemical composition.

2. Mechanical performance requirements: Different standards have different mechanical performance requirements for stainless steel square steel, mainly reflected in the ultimate tensile strength, yield strength, elongation and other indicators of the material.

3. Processing technology: Different standards also have different requirements for the processing operation of stainless steel square steel. For example, European standards require cold drawing manufacturing, while American standards do not have this requirement.

4、 Conclusion

Through the introduction in this article, we can understand the execution standards and application scope of stainless steel square steel, as well as the differences between different standards. This targeted information can help us choose stainless steel square steel more accurately and scientifically, avoiding material quality issues caused by non-compliance with standards.
