Product Details

Product Description:

In order to maintain stable passivation in oxidizing acid, stainless steel should have a chromium content of about 18%. When the chromium content is 18%, in order to obtain austenite structure at normal temperature, 8%-9% nickel should be added to the steel. And the raw material of this kind of seamless stainless steel tubes,1.4307  is like this.

Features:

  • Excellent corrosion resistance enables structural components to permanently maintain engineering integrity.

  • Combining mechanical strength and high extensibility, it is easy to manufacture parts to meet the needs of architects and structural designers.

  • High chromium content prevents further corrosion of the stainless steel.

  • Contains commonly used alloying elements to meet the requirements for a variety of applications.

Applications

Mainly used as fluid transport,hydraulic and mechanical systems, boiler and heat exchanger pipe, machined board,etc.
