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. |
- Q: How much more expensive is 304 stainless steel than 201?
- 201 in the stainless steel industry, represents a kind of material, 201 stainless steel is generally refers to 201 stainless steel and acid resistant steel floorboard. 201 stainless steel refers to the atmosphere, steam, water and other weak medium corrosion of steel, while acid resistant steel refers to acid, alkali, salt and other chemical corrosive medium corrosion of steel.
- Q: What is the average lead time for manufacturing stainless steel pipes?
- The average lead time for manufacturing stainless steel pipes can vary depending on several factors such as the complexity of the design, quantity required, and the manufacturer's production capacity. However, on average, it can range from a few weeks to a couple of months.
- Q: What does "stainless steel pipe 201304" mean?
- 304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry.
- Q: What is the welding of stainless steel?
- Many welding methods, commonly used argon arc welding, less thermal stress, less molten metal elements, forming beautiful; the remaining manual arc welding, higher requirements can be used when laser welding
- Q: Can stainless steel pipes be engraved?
- Indeed, it is possible to engrave stainless steel pipes. Engraving entails etching or carving designs, patterns, or text onto the surface of an object. Stainless steel is a versatile material that allows for engraving through different methods, including laser engraving, rotary engraving, or hand engraving. Laser engraving, in particular, is highly favored for stainless steel pipes due to its ability to create precise and enduring markings. These engravings can enhance the pipes' aesthetic appeal and also serve practical purposes, such as identification or branding. However, it is crucial to acknowledge that the depth and quality of the engraving may vary depending on the type and grade of stainless steel utilized.
- Q: Can stainless steel pipes be used for food storage tanks?
- Yes, stainless steel pipes can be used for food storage tanks. Stainless steel is a preferred material for food storage and processing equipment due to its excellent corrosion resistance, durability, and hygiene properties. It is non-reactive, does not leach any harmful substances into the food, and can withstand high temperatures and rigorous cleaning processes. Additionally, stainless steel pipes can be easily cleaned and sanitized, ensuring the maintenance of proper food safety standards. Therefore, stainless steel pipes are commonly used in the construction of food storage tanks to ensure the safety and quality of stored food products.
- Q: Under what circumstances can the stainless steel pipe be welded by argon arc, and under what conditions can the arc welding be used?
- From the economic point of view and flexibility, arc welding is good, from the efficiency aspect, of course, argon arc welding is higher, the effect is better, and also more mechanized. If it is small batch, it will choose arc welding.
- Q: What is the difference between Sch 40 and Sch 80 stainless steel pipes?
- The difference between Sch 40 and Sch 80 stainless steel pipes lies in their wall thicknesses. Sch 40 refers to a pipe with a wall thickness of "Schedule 40," while Sch 80 refers to a pipe with a wall thickness of "Schedule 80." The schedule number represents the approximate wall thickness of the pipe, with higher numbers indicating thicker walls. In the case of stainless steel pipes, Sch 80 has a thicker wall compared to Sch 40. The difference in wall thickness translates to differences in pressure rating and strength. Sch 80 stainless steel pipes are designed to handle higher pressure and are generally used in applications where the pipe needs to withstand higher levels of stress or extreme conditions. On the other hand, Sch 40 stainless steel pipes are commonly used in less demanding applications where lower pressure ratings are acceptable. Additionally, the thicker wall of Sch 80 pipes results in a smaller internal diameter compared to Sch 40 pipes. This reduction in internal diameter can impact the flow rate of fluids or gases through the pipe, so it is important to consider this factor when selecting the appropriate pipe for a specific application. In summary, the main difference between Sch 40 and Sch 80 stainless steel pipes is their wall thickness, with Sch 80 pipes being thicker and capable of handling higher pressure and stress levels.
- Q: How do stainless steel pipes compare to fiberglass pipes?
- Stainless steel pipes are known for their durability, strength, and resistance to corrosion, making them ideal for high-pressure and high-temperature applications. On the other hand, fiberglass pipes possess excellent corrosion resistance, lower thermal conductivity, and are lighter in weight. However, stainless steel pipes generally have a longer lifespan and require less maintenance compared to fiberglass pipes. Ultimately, the choice between stainless steel and fiberglass pipes depends on the specific requirements and conditions of the project at hand.
- Q: Stainless steel tube, also known as why tube?
- It can be divided into round tube and special-shaped tube according to the cross sectional shapeThe special-shaped tube has a rectangular tube, a rhombus tube, an elliptical tube, six square tubes, eight square tubes, various cross section asymmetric pipes, etc.
