Description of the equipment material

:Oh, I don’t think I’ve considered that question before. Strictly speaking, SS304L or something like that is required. The designs produced by design institutes are extremely strict. But when we place orders ourselves, it’s 304, 316, 2205 and so on.

For the national standard material 304, it should be written as S30408; refer to the material grade column in GB/T150.2 for details

When describing the material of a device, 304 stainless steel is usually labeled as “304” or “SS304”. "SS” stands for Stainless Steel. However, the designation “SS30403” is not common; usually, “03” is not added after “304”. Under international standards, the standard designation for 304 stainless steel was established by the American Society for Testing and Materials (ASTM). According to ASTM standards, 304 stainless steel is commonly referred to as AISI 304 or SAE 304; under the European standard EN 10088, this material is designated as 1.4301. If you need to view the specific regulations, you may need to refer to the following documents: 1. ASTM A240/A240M: This standard specifies the requirements for stainless steel plates, sheets, and strips used in pressure vessels and general applications. 2. EN 10088-1: This is a European standard that applies to stainless steels; it covers the composition and mechanical properties of such steels. More detailed descriptions and regulations may also be found in industry standards or documents specific to a particular field. Generally, the material and model of a device or its components should be specified in accordance with the specifications provided by the manufacturer or the project’s engineering standards. If you see a label such as “SS30403” in a specific document, it might be a special product code or internal identifier; you will need to consult that document or ask the person who created it to understand its exact meaning. In standard engineering practice, it is sufficient to use “SS304” to identify this material. .
