Definition of stainless steel(Adopted form Wikipedia)
In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable",
is defined as a steelalloy with a minimum of 10.5% to 11% chromium content by mass.
Stainless steel does not readily corrode, rust or stain with water as ordinary steel does,
but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity,
or poor circulation environments. It is also called corrosion-resistant steel or CRES
when the alloy type and grade are not detailed, particularly in the aviation industry.
There are different grades and surface finishes of stainless steel to suit the environment
the alloy must endure. Stainless steel is used where both the properties of steel
and resistance to corrosion are required.
Surface Finish :
Surface finish | Characteristics and application |
No.2B | The surface brightness and flatness of no2B is better than no2D. then through a special surface treatment to improve its mechanical properties, No2B could nearly satisfy comprehensive uses. |
No.3 | Polished with abrasive belt of git#100-#200, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc. |
No.4 | Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous coarse stria, but thinner than No3, are used as bathtub buildings inner and external ornaments electrical appliances kitchen utensils and food processing equipment etc. |
HL | Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streaks, mainly used as buildings ornaments elevators, door of building, frontal plate etc. |
BA | Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus, ornament etc. |
8K | The product have excellent brightness and prefer reflexivity can to be the mirror. |

It's important to consult the relevant standards and regulations for each specific application to ensure compliance with industry requirements and to ensure the safe and efficient use of stainless steel pipes.
- Q: What is the maximum temperature limit for stainless steel pipes?
- The specific grade of stainless steel used determines the maximum temperature limit for stainless steel pipes. In general, stainless steel pipes can tolerate high temperatures ranging from 1200°F (650°C) to 1600°F (870°C). However, it is important to consider the specific alloy composition, as certain grades of stainless steel possess greater temperature resistance than others. Moreover, the maximum temperature limit can be influenced by factors such as the duration of exposure to high temperatures and the presence of corrosive substances. Therefore, consulting the manufacturer's specifications or seeking professional guidance is crucial to accurately determine the maximum temperature limit for a specific application of stainless steel pipes.
- Q: Why is stainless steel magnetic?
- 304 stainless steel after cold processing, the structure of the structure will also change to martensite, and the greater the deformation degree of cold work, the more martensitic transformation, the greater the magnetic properties of steel. Like a lot of steel strips, the product is made up of 103 tubes, without obvious magnetic induction, producing 9.5 tubes. Due to the large deformation of the Ling bend, the magnetic sense is obvious, and the square tube produced by the utility model has larger deformation than the round tube, especially the folding part, the deformation is more intense, and the magnetism is more obvious. In order to completely eliminate the magnetic properties of the 304 steel caused by the above reasons, the stable austenite structure can be recovered by the solution treatment at high temperature so as to eliminate the magnetism. In particular, magnetic because it causes 304 stainless steel, and other materials such as stainless steel, carbon steel, magnetic 430 is not the same level, that is to say the magnetic steel 304 always showed a weak magnetic.
- Q: Are stainless steel pipes suitable for vacuum systems?
- Yes, stainless steel pipes are suitable for vacuum systems. Stainless steel has excellent corrosion resistance and high strength, making it ideal for handling the low pressure and potential moisture present in vacuum systems.
