What is the 201 J1 stainless steel tube

• 200 series stainless steel was born during World
  War II. The 201 stainless steel tube is also one
  of the product types.
• It has acid and alkali resistance. Moreover, its
  density is very high.
• Meanwhile, after people polished it, it has no
  bubbles or pinholes. It is also a raw material
  for decorative tubes, industrial tubes and some
  shallow stretched products.
• Due to the different compositions of 201
  stainless steel used in different fields, it has
  five types J1, J2, J3, J4, and J5.

The production process of 201 J1

• Use high-quality 304, 316L stainless steel raw
  material pipes to be empty, headed, and annealed.
  Then, people will cold-roll it many times. The
  cold-rolling of the pipe is carried out on a
  multi-roll mill. After cold rolling, the yield
  coefficient of the stainless steel tube is
  relatively large, and it is not easy to expand or
  bend.
• Therefore, to reach the sanitary standard of 201
  J1 stainless steel tube. People also need to
  demagnetize, pickle, and straighten stainless
  steel pipes.
• Meanwhile, when pickling passivating, people can
  remove oil stains, rust spots, welding spots,
  oxide layers, free iron, and other dirt on the
  surface of the workpiece.
• Then, people will polish 201 J1 stainless steel.
• After people finish the above steps, they will
  carry out a quality

Advantages of 201 J1 stainless steel tube

• First of all, due to its high hardness, it is
  very suitable for heavy-duty applications.
• Moreover, it has good corrosion resistance.
  Therefore, the maintenance it requires is
  minimal. Meanwhile, its service life is also very
  long.
• Compared with the 304 stainless steel pipe, it
  has oxidation resistance. Therefore, people can
  use it in high-temperature conditions with
  continuous temperature of 1200 degrees.

Disadvantage of 201 J1 stainless steel tube

• Because of the high chromium content and low
  nickel content cannot reach a balance, people
  will reduce its cadmium content to 15-16.
• Therefore, its corrosion resistance is not as
  good as other similar stainless steel tubes.
• Moreover, Manganese and copper reduce their
  passivate ability. Therefore, under acidic
  conditions, crevice corrosion often occurs.
• Even so, its application is still very extensive.

Application of 201 J1 stainless steel tube
In the transportation of various liquids and
fluids, people make good use of its pipeline
advantages. Moreover, it has strong corrosion
resistance. Therefore, the 201 J1 stainless
steel tube is widely used in oil refineries,
chemical processing, and food transportation.

Things you need to pay attention
The anti-rust treatment of stainless steel should
be Sa2.5 in GB/T8923. Moreover, the depth of its
surface anchor pattern is 40µm to 100µm. The
residual rust and dust on the surface of the 304
stainless steel pipe should be clean
