duplex ss grades

Duplex chrome steel grades have a range of corrosion resistance, similar to the range for austenitic stainless steels, i.e from Type 304 or 316 (e.g. LDX 2101©) to 6% molybdenum (e.g. SAF 2507©) stainless steels. The chromium, tungsten, nitrogen and molybdenum content in duplex and super duplex create the resistance to crevice corrosion and chloride pitting that makes these supplies so well-liked.

We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.

Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High strength
High toughness and impact resistance
Temperature resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean

What is duplex stainless steel pipe?

Duplex stainless steels are called “duplex” because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel. The result is a microstructure of roughly 50% austenite and 50% ferrite. Duplex stainless steels have a two-phase microstructure of austenite and ferrite grains.

Austral Wright Metals supplies a complete vary of stainless steels, copper alloys, nickel alloys and different high efficiency metals for difficult service situations. Our engineers and metallurgists will be pleased to offer further information and purposes advice. Ferralium® 255 – SD50 is a stainless steel which is equipped within the sizzling worked and annealed condition.

These steels also have resistance to chloride stress corrosion which is significantly larger than austenitic grades, with out sacrificing on sturdiness or ductility. Ferritic stainless steels possess a ferrite microstructure like carbon steel, which is a physique-centered cubic crystal structure, and include between 10.5% and 27% chromium with little or no or no nickel. This microstructure is present at all temperatures as a result of chromium addition, so they are not hardenable by warmth treatment.

  • Duplex stainless steels are based mostly around a composition of twenty-two% chromium, whereas super duplex stainless steels are primarily based around a composition of 25% chromium.
  • Types 304 and 316 stainless steels are normal supplies of construction involved with water.
  • Applications embody a variety of situations including plumbing, potable water and wastewater treatment, desalination, and brine treatment.
  • Stainless steels have a long history of software in touch with water due to their wonderful corrosion resistance.

Cold Rolled,Hot Rolled Stainless steel Plate and sheets

They cannot be strengthened by cold work to the identical diploma as austenitic stainless steels. The addition of nitrogen also improves resistance to pitting corrosion and will increase mechanical energy. Thus, there are quite a few grades of stainless-steel with various chromium and molybdenum contents to suit the setting the alloy must endure.

Alloy 2205 is a 22% Cr duplex stainless steel, supplied in the resolution annealed condition. As a duplex stainless steel, it combines the fascinating facet of properties of each austenitic and ferritic grades. The high chromium, molybdenum and nitrogen contents results in a Pitting Resistance Equivalent variety of 33-34. Sanmac® 2205 is a 22% Cr duplex stainless-steel with improved machinability as normal.

Due to the decrease alloying content material, duplex stainless steels could be lower in value, particularly in occasions of excessive alloy surcharges. Additionally, it may usually be potential to scale back the section thickness of duplex stainless steel, due to its elevated yield energy compared to austenitic stainless-steel. The combination can result in important price and weight financial savings compared to a solution in austenitic stainless steels. Duplex and tremendous duplex belong to a family of stainless steels which are characterised by a mix of easy fabrication, high power and wonderful corrosion resistance.
