Description Product DescriptionStainless steel pipe is a kind
of hollow long round steel, which is mainly used in industrial
transportation pipelines and mechanical structural components such
as petroleum, chemical industry, medical treatment, food, light
industry, mechanical instrument and so on. In addition, when the
bending and torsional strength are the same, the weight is lighter,
so it is also widely used in the manufacture of mechanical parts
and engineering structures. It is also commonly used as furniture
and kitchenware. It has the following
characteristics: 1. Weldability
Different product uses have different requirements for welding
performance. A class of tableware generally does not require
welding performance, and even includes some pot enterprises.
However, most products require good welding performance of raw
materials, such as second-class tableware, thermos cups, steel
pipes, water heaters, water dispensers, etc.2. Corrosion
resistance Most stainless steel products require good
corrosion resistance, such as Class I and II tableware, kitchen
utensils, water heaters, water dispensers, etc. Some foreign
merchants also do corrosion resistance tests on the products: use
NACL aqueous solution to heat it to boiling, and pour it after a
period of time. Remove the solution, wash and dry, and weigh the
weight loss to determine the degree of corrosion (Note: When the
product is polished, the Fe content in the abrasive cloth or
sandpaper will cause rust spots on the surface during the test)3.
Polishing performance In today's society, stainless
steel products are generally polished during production, and only a
few products such as water heaters and water dispenser liner do not
need polishing. Therefore, this requires that the polishing
performance of the raw material is very good. The main factors that
affect the polishing performance are as follows:(1)Surface defects
of raw materials. Such as scratches, pitting, pickling, etc.(2)The
problem of raw materials. If the hardness is too low, it will not
be easy to polish when polishing (the BQ property is not good), and
if the hardness is too low, the orange peel phenomenon is easy to
appear on the surface during deep drawing, thus affecting the BQ
property. BQ properties with high hardness are relatively
good.(3)For the deep-drawn product, small black spots and RIDGING
will appear on the surface of the area with a large amount of
deformation, thus affecting the BQ performance.4. Heat
resistance Heat resistance means that stainless steel
can still maintain its excellent physical and mechanical properties
at high temperatures.Influence of carbon: Carbon is an element that
strongly forms and stabilizes austenite and expands the austenite
region in austenitic stainless steels. The ability of carbon to
form austenite is about 30 times that of nickel, and carbon is an
interstitial element that can significantly increase the strength
of austenitic stainless steel through solid solution strengthening.
Carbon can also improve the stress corrosion resistance of
austenitic stainless steel in highly concentrated chloride (such as
42% MgCl2 boiling solution).Product ParametersProduct nameStainless
