316 stainless steel pipe
Metals used in petroleum, chemical, medical, food and light industry
316 stainless steel pipe is a kind of hollow long round steel, which is widely used in oil, chemical, medical, food, light industry, mechanical instruments and other industrial transmission pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is relatively light, so it is also widely used to manufacture mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, etc.
The maximum carbon content of 316 stainless steel pipe is 0.03, which can be used in applications where annealing is not allowed after welding and maximum corrosion resistance is required.
316 and 317 stainless steels (see below for the properties of 317 stainless steels) are molybdenum containing stainless steels.
The overall performance of this steel is better than 310 and 304 stainless steel. At high temperature, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses.
316 stainless steel plate, also known as 00Cr17Ni14Mo2, corrosion resistance:
The corrosion resistance is better than 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper.
The carbide precipitation resistance of 316 stainless steel is better than that of 304 stainless steel, and the above temperature range can be used.
Varieties: 316 stainless steel tubes, 316 stainless steel bright tubes, 316 stainless steel decorative tubes, 316 stainless steel capillary tubes, 316 stainless steel welded tubes, 304 stainless steel tubes.
The maximum carbon content of 316L stainless steel pipe is 0.03, which can be used in applications where annealing is not allowed after welding and maximum corrosion resistance is required.

As stainless and heat-resistant steel, 304 steel pipe is the most widely used equipment for food, general chemical equipment and atomic energy industry.
304 steel pipe is a kind of universal stainless steel pipe, which is widely used to make equipment and parts requiring good comprehensive performance (corrosion resistance and formability).
304 steel pipe has excellent rust and corrosion resistance and good intergranular corrosion resistance.
304 steel pipe material has strong corrosion resistance in nitric acid below boiling temperature with concentration ≤ 65%. It also has good corrosion resistance to alkali solution and most organic and inorganic acids. A kind of high alloy steel that can resist corrosion in the air or in the chemical corrosion medium. Stainless steel is a kind of steel that has beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as color plating, but gives full play to the inherent surface properties of stainless steel. It is used in many aspects of steel, usually called stainless steel. High alloy steels such as 13 chromium steel and 18-8 chromium-nickel steel are representative of properties.
As stainless and heat-resistant steel, 304 steel pipe is the most widely used equipment for food, general chemical equipment and atomic energy industry.

201 stainless steel pipe
Marking method
201 stainless steel pipe – S20100 (AISI. ASTM)
American Iron and Steel Institute uses three digits to mark various standard grade malleable stainless steel floors. Including:
① Austenitic stainless steel is marked with 200 and 300 series of numbers;
② Ferritic and martensitic stainless steels are represented by 400 series numbers.
For example, some common austenitic stainless steels are marked with 201, 304, 316 and 310, ferritic stainless steels are marked with 430 and 446, martensitic stainless steels are marked with 410, 420 and 440C, and duplex (austenitic-ferritic) stainless steels, precipitation hardening stainless steels, and high alloys with iron content less than 50% are usually patented or trademarked.
Purpose performance
201 stainless steel tube has the characteristics of acid resistance, alkali resistance, high density and no pinhole. It is used to produce various high-quality materials such as case and bottom cover of watch band. 201 stainless steel pipe can be mainly used in decorative pipe, industrial pipe and some shallow stretched products.

Galvanized pipe
Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and has the advantages of uniform coating, strong adhesion and long service life. The cost of electro galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipe.
