1.4003 materials chrome steel supplier

We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.

This mixture of properties can imply some compromise when compared with pure austenitic and pure ferritic grades. The chromium, molybdenum, and nitrogen in 2205 duplex stainless-steel plate also provide excellent resistance to pitting and crevice corrosion even in very oxidizing and acidic solutions. Corrosion resistance is a crucial component of supplies built to withstand natural disasters. Duplex stainless steel is much less prone to damage by stress corrosion cracking. It also provides good corrosion fatigue power and its microstruction and small carbon magnitude allow duplex steel to stand up against intergranular assault.

Composed of between 21% to 23% chromium, four.5% to 6.5% nickel, 5% to 3.5% molybdenum, 2% manganese, and 1% silicon, with the balance being iron. Also found in Duplex Stainless Steel are hint quantities of carbon, phosphorus, sulfur and nitrogen. Even in chloride and sulphide environments, duplex stainless steels exhibit very excessive resistance to stress corrosion cracking. 2205 is a duplex stainless-steel, with a chemical composition of nearly equal proportions of austenite and ferrite. This mixture allows the alloy to be stronger and harder than commonplace austenitic steels.

SAF 2205 or Duplex 2205 is often used as an alternative to costly 904L chrome steel owing to similar properties but cheaper ingredients. Duplex chrome steel is out there in multiple varieties like bars, billets, pipes, tubes, sheets, plates and even processed to fittings and flanges. More lately, it has been available complying with the higher corrosion resistant composition UNS S32205. The solely distinction in the UNS numbers is that UNS S32205 accommodates a better nitrogen content material which guarantees better corrosion resistance.


Our stainless production range

  • Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, three% molybdenum, 5 to 6% nickel alloyed chrome steel.
  • It additionally demonstrates good fatigue power, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.
  • It is the most extensively used duplex stainless steel grade and is characterized by high yield energy, double that of the standard austenitic chrome steel grades.


Alloy 2205 duplex stainless-steel plate offers pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steels in nearly all corrosive media. It additionally has high corrosion and erosion fatigue properties in addition to decrease thermal growth and better thermal conductivity than austenitic. Grade 2205 stainless-steel exhibits wonderful corrosion resistance, a lot greater than that of grade 316.

2205 material

S31803 was endorsed in year 1996 whereas it underwent variety of adjustments that led to discovery of UNS S32205 which is extra broadly used. Possible alternates for SAF 2205 are 904L Stainless Steel, UR52N+, 6%Mo and 316L.

The Helix in Marina Bay, Singapore and the Harbor Drive Pedestrian Bridge in San Diego, CA both use 2205 as a major structural materials offering high power, sustainable structures with slicing-edge design. Duplex 2205 Stainless Steel (each austenitic and ferritic) is utilized in purposes that require strength and good corrosion resistance.

High corrosion-resistant and high strength UNS S32205 can face up to the brackish or salt water impression of a coastal flood surge. This high quality together with long service life and low upkeep requirements led to the use of 2205 duplex chrome steel in pedestrian bridges.
