Stainless steel pipe Marking method of international precision stainless steel

AIS uses three digits to indicate various standard grades of malleable stainless steel. Among them:

Austenitic stainless steel of stainless steel pipe plant is marked with numbers of 200 and 300 series,

Ferritic and martensitic stainless steels are represented by 400 series numbers. For example, some of the more common austenitic stainless steels

It's 201 three hundred and four , 316 and 310,

In the stainless steel pipe plant, the ferrite stainless steel is marked with 430 and 446, and the martensitic stainless steel is marked with 410, 420 and 440C

Two phases (austenite ferrite),

Stainless steel, precipitation hardening stainless steel and high alloy with iron content less than 50% are usually named by patent or trademark.

Precision stainless steel pipe is safe and reliable, hygienic and environmental protection, economical and applicable. The thin wall of the pipe and the development of new reliable, simple and convenient connection method make it have more and more advantages which can not be replaced by other pipe materials. The application in engineering will be more and more, the use will be more and more popular, and the prospect is promising.

With the implementation of China's reform and opening up policy, the national economy has achieved rapid growth, urban housing, public buildings and tourism facilities are being built in large quantities, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality. Galvanized steel pipe, as a common pipe material, is easy to corrode. Under the influence of relevant national policies, galvanized steel pipe will gradually withdraw from the historical stage. Plastic pipe, composite pipe and copper pipe have become the common pipe materials of pipeline system. However, in many cases, the stainless steel pipe has more advantages, especially the thin-walled stainless steel pipe with wall thickness of 0.6-1.2mm has the characteristics of safety, reliability, environmental protection, economy and applicability in high-quality drinking water system, hot water system and water supply system which puts safety and sanitation in the first place. It has been proved by engineering practice at home and abroad that it is one of the best, new, energy-saving and environmental protection pipes for water supply system. It is also a kind of competitive water supply pipe material, which will play an incomparable role in improving water quality and people's living standard.
