Duplex round bar supplier in India

What is a duplex round bar?

This bar comprises austenitic and ferritic grades of stainless steel for superior corrosion resistance. A duplex round bar uses a nitrogen-enhanced composition to show top-notch weldability, yield strength, and machinability. Grade 2205 is the most widely used DSS bar. It comprises chromium and nickel in proportions of 22% and 5%. Buyers can acquire a DSS rod with peeling, annealing, polishing, grinding, etc.

What are the applications of DSS rods?

The preferred usesof a DSS bar are heat-based applications like heat exchangers, boilers, condensers, exhausts, and cooling towers. A DSS round bar also works in power generation, fertilizers, and chemical processing.Resistance to rust, cracking, and pitting are beneficial in flue gas desulfurization, bleaching, and oil field piping.

Types of DSS rod

We are proud to be the benchmark for quality and reliability in duplex steel round bar and ASTM A276 duplex steel bars. To ensure that our customers receive the best materials, we utilize the most up-to-date testing methods

How does testing an astm a276 duplex steel square bar ensure quality?

Industry practice is to subject astm a276 DSS bars to tensile and hardness testing, radiography, spectrometry, and positive material identification (pmi). Manufacturers also check the quality of a DSS rod through tests for pitting resistance and intergranular corrosion (igc).

Our duplex steel bar and DSS square bars are unparalleled in their strength and resistance to wear and corrosion.

How does the composition of duplex steel bars affect their strength and resistance to wear and corrosion?

These bars deliver corrosion resistance and tolerance for wear and tear. The microstructure of a DSS bright bar comprises austenitic and ferrite grades in equal proportions, lending it resistance to chlorides. A DSS square bar can resist stress-propagated cracking, pitting,and crevice erosion.

What is the unique blend of materials used in asme sa276 duplex bars?

These products combine chromium, nickel, and molybdenum with small amounts of silicon, manganese, phosphorus, carbon, and sulphur. A DSS cold drawn bar benefits from these elements: increased strength, toughness, and corrosion resistance at high temperatures. The amounts are usually 22% chromium, 3% molybdenum, and up to 5% nickel.
