Stainless steel pipes have been popular in recent years. Stainless steel pipes have good properties like corrosion resistance and good toughness. Therefore, stainless steel pipes have been widely applied in many fields. However, most of people only know the good performance of stainless steel pipes but don’t know why they have so many good properties. The stainless steel pipe composition has a strong relationship with the properties of the pipes.
The major components of stainless steel are: iron, chromium, carbon, nickel, molybdenum and small quantities of other metals. Here I would like to introduce some of stainless steel pipe compositions to you.
1. One of the most important stainless steel pipe compositions – Chromium
Chromium is the element that makes stainless steel stainless. It is essential in forming the passive film. Other elements can influence the effectiveness of chromium in forming or maintaining the film. However, no other element by itself can create the properties of stainless steel. The Chromium will provide mild atmospheric protection for stainless steel pipes and with the increasing of chromium content, stainless steel pipes can be denser and harder.
2. Stainless steel pipe composition for corrosion resistance – Nickel
Nickel will stabilize the austenitic structure (the grain or crystal structure) of the stainless steel pipes and enhance the mechanical properties and fabrication characteristics at the same time. The tendency of the metal to crack can be decreased if the content of nickel is enhanced. Nickel also promotes repassivation in case the film is damaged.
3. The new stainless steel pipe compositions – Titanium and Miobium
Titanium and Miobium are two compositions which are used to reduce the sensitization of stainless steel pipes. If the stainless steel pipes are sensitized, there will be intercrystalline corrosion. Titanium and Niobium interact with carbon to form carbides, leaving the chromium in solution. As a result, a passive film can form.
In addition to these stainless steel pipe compositions, there are many other components of stainless steel pipes. For example, Copper and Aluminum, along with Titanium, can be added to the stainless steel pipe to precipitate its hardening. Carbon can increase the strength of the stainless steel pipes.
We will be in need of various kinds of stainless steel pipes for different applications. If there is a need, Shangshang is willing to provide all kinds of high-quality stainless steel pipes and stainless steel pipe fittings for customers from all over the world. Competitive price and good after-sales service can be ensured.
