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 :

- Q: What is the difference between ERW and EFW stainless steel pipes?
- ERW (Electric Resistance Welded) and EFW (Electric Fusion Welded) are two different methods used for manufacturing stainless steel pipes. The main difference between the two lies in the welding process. ERW stainless steel pipes are manufactured by rolling a flat sheet of steel into a cylindrical shape and then welding the edges together using a high-frequency electrical current. This process creates a strong, seamless joint between the two edges of the sheet, resulting in a pipe that is highly resistant to corrosion and has a smooth interior surface. ERW pipes are commonly used in applications where strength and durability are required, such as in the oil and gas industry. On the other hand, EFW stainless steel pipes are made by applying a combination of heat and pressure to melt the edges of two pieces of steel and then welding them together. This fusion welding process results in a pipe that has a continuous weld along its entire length, eliminating the need for any additional welding. EFW pipes are known for their excellent corrosion resistance and are often used in applications where high-pressure and high-temperature conditions are present, such as in chemical plants and power generation facilities. In summary, the main difference between ERW and EFW stainless steel pipes lies in the welding process. ERW pipes are made by welding the edges of a flat sheet, while EFW pipes are made by fusing the edges of two pieces of steel. Both methods have their respective advantages and are used in different applications depending on the specific requirements of the project.
- Q: Can stainless steel pipes be insulated with rubber?
- Indeed, rubber insulation can be applied to stainless steel pipes. Employing rubber insulation is a prevalent technique for safeguarding and insulating diverse pipe varieties, encompassing stainless steel pipelines. With rubber insulation, numerous advantages manifest, such as thwarting heat loss or gain, minimizing condensation, and furnishing soundproofing attributes. Moreover, it demonstrates resistance against moisture, chemicals, and UV rays, thereby rendering it suitable for employment in both indoor and outdoor settings. Furthermore, rubber insulation installation and maintenance pose no challenge, thereby rendering it a cost-efficient selection for insulating stainless steel pipes.
- Q: What is the working temperature range for stainless steel pipes?
- The working temperature range for stainless steel pipes depends on the specific grade of stainless steel being used. Generally, stainless steel pipes can withstand a wide range of temperatures, from extremely low temperatures to high temperatures. For austenitic stainless steel grades, which are the most commonly used in pipe applications, the working temperature range is typically from -196°C (-320°F) to 816°C (1500°F). These grades, such as 304 and 316, exhibit excellent heat resistance and can maintain their strength and corrosion resistance even at elevated temperatures. However, it is important to note that the working temperature range can vary depending on the specific alloy composition and the application requirements. Some specialized stainless steel grades, such as duplex or super duplex stainless steels, may have different temperature limits due to their unique characteristics. It is always recommended to consult the manufacturer's specifications and guidelines to determine the specific working temperature range for a particular grade of stainless steel pipe. Additionally, considering factors such as pressure, corrosive environment, and thermal cycling should also be taken into account when determining the appropriate working temperature range for stainless steel pipes.
