Specifications
TOBO International (Shanghai) Co.,Ltd.Specializing in the production of 1.4539 duplex stainless steel pipe
1. 1. 904L, domestic brand00 cr20ni25mo4s. 5 cu. A,merican standard NO8904, vary with different usages.
C content < = 0.02% or 0.03% ,with high content of chromium and enough nickel conten. The
addition of copper makes it has strong acid resistance, especially highly resistance to
chloride clearance corrosion and stress corrosion cracking. 2. Its pitting resistance also
slightly better with other types of steel,with good machinability and weldability. Application: pressure vessels. 3. This kind of steel developed with the application and development of of all kinds of sulfuric acid corrosion. Steel is gradually popularized on the market at present.
Main features: have high content of chromium and enough nickel content, especially highly resistance to chloride clearance corrosion and stress corrosion cracking.The pitting corrosion resistance is slightly better with other materials.
Application scope: Petroleum/Power/Chemical use/Construction use /Gas/Mechanism/Shipbuilding
