Stainless steel material is a kind of corrosion-resistant steel

Many people have misunderstandings about stainless steel material, and even distort the facts. In this regard, KAYSUNS will give a simple explanation on the aspects that are easily misunderstood and not well understood.

There are too many specifications and varieties of stainless steel pipes, is it a sign of industry confusion?

This is wrong. There are many varieties and specifications of stainless steel pipes because different stainless steel varieties are suitable for different downstream products. The variety of stainless steel pipes is numerous and complex, but it is a very professional performance in the stainless steel field.

Is 304/2B stainless steel the best stainless steel?

There is no such thing as the best stainless steel, and the most suitable stainless steel variety should be selected according to downstream needs. For example: 304 stainless steel pipe has better mechanical properties and is generally more suitable for simple mechanical processing, while 310S stainless steel, because of its stronger high temperature resistance and corrosion resistance, is often used in boilers, stainless steel heat exchanger tubing, etc. High temperature corrosive environment.

The right is the best.

Is the main reason why stainless steel can prevent corrosion because it contains electrolytic nickel?

This understanding is not accurate.

Electrolytic nickel does have an anti-corrosion effect. However, in austenitic stainless steel, electrolytic nickel is only used to build austenite crystals to improve the mechanical properties of the stainless steel, not corrosion resistance. Therefore, it is not stainless steel that contains electrolytic nickel.

The 400 series stainless steel does not contain electrolytic nickel, but it also has corrosion resistance. Due to the corrosion resistance of stainless steel, it mainly comes from ferrochrome.

Regular stainless steel with ferrochrome content above 12% can have preliminary anti-corrosion performance.

Are the elements of stainless steel material only iron, nickel, ferrochrome and carbon?

According to different requirements for downstream use of stainless steel, the metal content of stainless steel is in addition to the above four essentials. Some also contain copper (optimized mechanical properties, antibacterial properties), molybdenum (high temperature resistance), cobalt (high temperature resistance) and other elements.

The different content of related elements will also affect the strength of related properties.
