Product Description

**4l raw material round pipe seamless stainless steel tube export

Grade **4L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade **4L is non-magnetic, and offers excellent formability, toughness and weldability.

Corrosion Resistance

Grade **4L stainless steels have excellent resistance to warm seawater and chloride attack. The high resistance of grade **4L against stress corrosion cracking is due to the presence of high amounts of nickel in its composition. Moreover, the addition of copper to these grades develops resistance to sulphuric acid and other reducing agents in both aggressive and mild conditions.

Applications

Some of the major applications of grade **4L stainless steels include:

• Wiring in electrostatic precipitators
• Oil refinery components
• Seawater cooling devices
• Gas scrubbing plants
• Pulp and paper processing industries
• Acetic, phosphoric and sulphuric acid processing plants
