Holic Oil Pipeline Co., LTD.
Stainless Steel Welded Pipe Basics:
The stainless steel pipe is a high carbon steel pipe made of stainless steel materials. Its chromium content is relatively high comparing with other carbon steel pipes, mild steel pipes so it is often called High alloy steel pipes by insiders of steel industry. So what exactly is stainless steel and how to choose quality stainless steel pipes? As senior and trusted steel manufacturer, we will give you the answers.
What is Stainless Steel Pipe?
Stainless steel refers to the alloy steel which can resist the corrosion of weak corrosive medium such as air, steam, water and chemical corrosive medium such as acid, alkali and salt. The corrosion resistance of stainless steel depends on the alloy elements contained in the steel. The basic alloy elements of stainless steel include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc.
Stainless steel belongs to alloy steel, a kind of high alloy steel, which contains a lot of chromium, enough nickel and a certain amount of titanium. The role of chromium is to make the steel corrosion resistant, and the role of nickel is to reduce the austenitizing temperature of stainless steel. The total content of alloy elements can reach 10-28%, so it is a high alloy steel.
Advantages of stainless steel pipes
- Luster and Polishing surface
Our stainless steel is polished to ensure quality.
- Corrosion resistance
When the content of chromium atom in steel is not less than 12.5%, electrochemical corrosion can be prevented. Most stainless steel products are required to have good corrosion resistance, such as tableware, kitchen utensils, water heaters, water dispensers, etc. Some foreign buyers also test the corrosion resistance of the products.
- Excellent Solderability
Most of the finished products of stainless steel must have good weldability. Therefore, our stainless steel supplier can provide you with stainless steel with good weldability.
- Heat resistance
Stainless steel still has good physical and mechanical properties at high temperature.
Usage of stainless steel pipe
Although stainless steel pipes are higher cost to sources, according to its outstanding characteristics such as strength, anti rust, corrosion-resistance, stainless steel pipes have been applied in many industries and domains below
- Medical industry,
- Food and catering sector,
- Automotive and transportation industry,
- Construction and architecture domain,
- Energy and heavy industries.
