Characteristics of stainless steel threaded fittings 304/201/316
Although all are stainless steel, each material has different advantages. Thanks to that, it creates accessories with different characteristics. Specifically:
201 stainless steel threaded fitting
Stainless steel 201 has lower chromium and nickel content than stainless steel 304 and 316. This makes stainless steel 201 cheaper but also less durable in terms of corrosion resistance.
Advantages: Low cost, easy to process.
Disadvantages: Poor corrosion resistance, susceptibility to rust in humid environments or exposure to chemicals.
Disadvantages: Poor corrosion resistance, susceptibility to rust in humid environments or exposure to chemicals.
- Interior: Railings, handrails, door frames, etc.
- Decoration: Interior and exterior decoration products.
304 threaded stainless steel fitting
Stainless steel 304 has higher chromium and nickel content, enhancing corrosion and heat resistance. This is the most common and widely used stainless steel.
Advantages: Good corrosion resistance, good heat resistance, easy to process, reasonable price.
Disadvantages: May corrode in some highly acidic environments.
Application: Widely used in many fields such as:
- Food industry: Tanks, pipes.
- Construction: Railings, stairs, roofs.
- Healthcare: Medical equipment.
316 stainless steel threaded fittings
Stainless steel 316 has the highest chromium and nickel content of the three types of stainless steel and also has an additional molybdenum content. This gives stainless steel 316 superior corrosion resistance, especially in environments containing salt and chlorine. But because of that, it is much more expensive than the other two types.
Advantages: Excellent corrosion resistance, good heat resistance, and resistance to acids and salts.
Disadvantages: The highest price of the three types of stainless steel.
Application: Used in harsh environments such as:
- Chemical industry: Chemical tanks, pipelines.
- Oil and gas industry: Offshore equipment.
- Medical: High-end medical equipment.
