Find more useful tips for buying stainless steel coils in this article.
It's easy to get confused when choosing stainless steel coils. There are over 60 grades of stainless steel and many products to choose from.
At Xinnorda Stainless, we'll help you choose the stainless steel coil that's best for your project. In other words, you'll find some guidance and solutions before you decide to buy stainless steel coils.
First, let's take a look at some basic factors. You should take them into account in order to choose the product that meets all your expectations. If you need more advice, please contact our professional team. We will help you find the right product.
The following are the key factors to consider when purchasing stainless steel coils based on your needs.
Stainless Steel Coil
For stainless steel products, the installation environment is a key factor. When selecting stainless steel, we primarily consider atmospheric conditions, concentration levels of specific chemicals and acids.
If the installation environment is less corrosive, a general purpose grade of austenitic stainless steel is appropriate. For highly acidic environments, you will need to select a stainless steel grade such as 316.
Ambient temperature is also an important factor. In a furnace environment (900-1175C), high temperatures accelerate the corrosion of stainless steel.
In addition, it puts additional stress on the stainless steel product. Therefore, if the temperature is consistently high, a stainless steel with good heat resistance is required.
Very low temperatures are another factor. Austenitic stainless steels are effective at very low temperatures. They maintain higher tensile strength at low temperatures than at ambient temperatures. Despite a slight decrease in toughness, these steels work well at temperatures down to -161°C.

Austenitic grades have a low magnetic response. Those with higher nickel content are not magnetic under any conditions, such as 316 or 310 grades. Ferritic and martensitic stainless steel grades (400 series) have high permeability.
Steel strength is an important factor to consider before you choose a grade, but it is a complex one. Your stainless steel requirements depend on the application and installation environment.
In some cases, high-strength stainless steels, such as austenitic and duplex stainless steels, are appropriate. But in some cases, they also have obvious disadvantages and do not meet your requirements.
For example, high-strength austenitic steel produced through process hardening is not suitable for welding. It softens the steel.
Stainless steel products are available in a variety of forms, such as stainless steel plate, stainless steel bar and stainless steel pipe. Not all grades are available in all product forms and sizes. Austenitic stainless steel is versatile.
Stainless Steel Pipes
You can find products in a variety of forms and sizes for different applications. Ferritic steels are usually found in sheet form. Martensitic steels usually come in the form of solid bars.
When installing stainless steel products, there may be special requirements. Therefore, you may need to change the grade of the steel.
For example, you may need a non-magnetic steel, a product suitable for welding or a product with a high degree of formability. Or maybe you just want a good looking product.
Cost is always a factor when choosing a stainless steel coil to buy. You need to balance it with all other considerations. Sometimes the best technical steel is too expensive.
But remember to evaluate cost on a life cycle basis. Don't just look at the initial price and then ignore the life cycle. Stainless steel products last a long time, so the high cost of quality steel is justified.
