Five-star hotel stainless steel standards

1. National grade standards for stainless steel materials: Common stainless steels are 201 and 304.

2. The composition of 201 is 17Cr-4.5Ni-6Mn-N, which is a Ni-saving steel type and a substitute steel for 301 steel. It becomes magnetic after cold working. 201 has a high manganese content, and the surface is very bright with dark brightness. The high manganese content makes it easy to rust. Corrosion resistance is poor.

3. 304 is composed of 18Cr-9Ni, which is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc. 304 contains more chromium, has a matte surface and does not rust. Strong corrosion resistance.

Expansion: Five-star refers to a hotel whose comprehensive level reaches five-star. The classification of hotel stars is based on the hotel's architecture, facilities and equipment, functions, management, and service levels. The specific assessment methods are implemented in accordance with the facilities and equipment assessment standards, facility and equipment maintenance assessment standards, cleanliness assessment standards, and guest opinion assessment standards issued by the National Tourism Administration.
