Super duplex plate

Super duplex plate

What is a super duplex plate?

This material comprises iron, chromium, nickel, and molybdenum. This composition boosts corrosion resistance and other metallurgical properties. A super duplex plate enjoys the advantages of ferritic and austenitic grades. For example, grade 2507 has 25% chromium and 7% nickel,with molybdenum up to 4%.It works extensively in heat-based applications, chemical processing, aerospace, and general engineering.

SDSS sheet supplier in India

What are the benefits of using a super duplex plate in construction and engineering?

We are Super duplex plate supplier in India, our SDSS sheet gets employed in construction, fabrication, and engineering works due to strength and durability. It has a pren greater than 40 and a high yield strength. Additionally, it offers good weldability through standard techniques like gas tungsten arc or submerged arc welding. This material resists corrosion, lowering downtime and maintenance. It is machinable and suitable for drilling and grinding with high-speed or traditional tools. A super duplex steel plate works safely and efficiently in marine environments, bridges, and heavy construction.

Our eddy current and ultrasonics testing procedures for SDSS strip are designed to detect even the slightest defects

What is the purpose of using eddy current and ultrasonics testing methods for super duplex plates?

Stringent testing of a SDSS plate is mandatory to ensure quality standards, chemical composition, and mechanical properties.The typical procedures are eddy current and ultrasonic testing to identify surfaceflaws. These non-destructive tests check for internal and external defectslikecracks, laminations, etc.

Which testing is required to ensure the chemical composition of super duplex material?

Determining the composition of a SDSS perforated sheetcertifies its fitment for critical applications in defence and aerospace. The industry-standard test is spectrometry using automated spectrometers. Manufacturers use x-ray fluorescence or a spark metal composition test to ascertain the microstructure.
