Why are so Many Stainless Steel Pipes Used in Coastal Areas?

As a Black Seamless Steel Pipe Supplier, share with you. Why are stainless steel pipes so popular in coastal areas? We all know that seawater is salty, unlike freshwater in rivers and rivers, which contains a lot of chlorine, which can react with metals and accelerate metals of corrosion.

Why are stainless steel pipes so popular in coastal areas? We all know that seawater is salty, unlike freshwater in rivers and rivers, which contains a lot of chlorine, which can react with metals and accelerate metals Of corrosion. But for 316 stainless steel pipe, 316 stainless steel pipe has very good corrosion resistance, 316 stainless steel can be used for a long time in the marine environment, so people near the ocean or working at sea will use 316 stainless steel pipe to use.

The stainless steel pipe contains molybdenum (Mo) element, which makes the stainless steel pipe itself has very strong corrosion resistance. Although seawater and normal atmosphere have many other corrosive chemicals in addition to chlorides, these 316 stainless steel pipes that are particularly resistant to corrosion is not a problem.

People often think that magnets attract stainless steel to verify its merits and authenticity. It does not attract non-magnetic materials. It is considered good and genuine. If the attractor is magnetic, it is considered fake. In fact, this is an extremely one-sided, impractical method of identifying errors.

There are many types of stainless steel, which can be divided into several categories according to organizational structure at room temperature:

1. Austenitic type: such as 304, 321, 316, 310, etc.;

2. Martensite or ferrite type: such as 430, 420, 410, etc.;

The austenite type is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic.

The most commonly used stainless steel for decorative tube sheets is austenitic 304 material. Generally speaking, it is non-magnetic or weak-magnetic, but the magnetic composition may fluctuate due to smelting or the processing state may be different. However, this cannot be considered as Counterfeit or unqualified, what is the reason?

As mentioned above, austenite is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic. Due to segregation of components during smelting or improper heat treatment, it will cause a small amount of martensite or ferrite in austenitic 304 stainless steel. Body organization. In this way, 304 stainless steel will have a weak magnetic.
