    Zecor Stainless Steel offers several grades suitable for applications in sulphuric acid plants, where corrosion resistance and durability are paramount. The specific grade selection depends on factors such as temperature, concentration of sulphuric acid, and the presence of other corrosive elements. Here are some commonly used Zecor Stainless Steel grades for sulphuric acid plant applications:

    1. Zecor 316 Stainless Steel: This grade is renowned for its excellent corrosion resistance in a wide range of corrosive environments, including sulphuric acid environments. Zecor 316 contains molybdenum, which enhances its resistance to pitting and crevice corrosion in acidic conditions.

    2. Zecor 904L Stainless Steel: Known for its high resistance to sulphuric acid corrosion, Zecor 904L is a non-stabilized austenitic stainless steel with low carbon content. Its high nickel and chromium content, along with additions of copper and molybdenum, make it exceptionally resistant to both uniform and localized corrosion in sulphuric acid environments.

    3. Zecor 2205 Duplex Stainless Steel: This duplex stainless steel grade offers a combination of high strength and excellent corrosion resistance, making it suitable for sulphuric acid plant applications where both mechanical performance and resistance to corrosion are required. Zecor 2205 contains a balanced mix of chromium, molybdenum, and nitrogen, providing enhanced resistance to stress corrosion cracking and pitting corrosion in acidic environments.

    4. Zecor AL-6XN Stainless Steel: Engineered for extreme corrosion resistance, Zecor AL-6XN is a super-austenitic stainless steel grade with high levels of chromium, nickel, molybdenum, and nitrogen. It offers superior resistance to chloride-induced pitting, crevice corrosion, and stress corrosion cracking, making it suitable for aggressive sulphuric acid plant conditions.

    5. Zecor C-276 Stainless Steel: This nickel-molybdenum-chromium alloy offers exceptional resistance to a wide range of corrosive media, including sulphuric acid environments containing oxidizing and reducing agents. Zecor C-276 provides excellent resistance to both uniform and localized corrosion, making it a reliable choice for sulphuric acid plant equipment exposed to highly corrosive conditions.

    Before selecting a specific Zecor Stainless Steel grade for a sulphuric acid plant application, it’s essential to consult with materials engineers and corrosion experts to ensure compatibility with the operating conditions and regulatory requirements of the plant. Additionally, proper material selection, fabrication, and maintenance practices are crucial for maximizing the performance and longevity of stainless steel equipment in sulphuric acid service.


    It has excellent corrosion resistance in high-temperature concentrated sulfuric acid and has the characteristics of resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking.

    It overcomes the shortcomings of brittle silicon-rich phase and poor hot workability of high-silicon stainless steel and has good plastic deformation performance.
