2205 & 2507 Stainless Steel


duplex alloy 2205

Our stainless production range

Below 1700°F there can be speedy formation of intermetallic phases because of the mixture of temperature and deformation. Whenever hot forming is finished, it ought to be followed by a full resolution anneal at 1900°F minimum and rapid quench to restore section stability, toughness, and corrosion resistance.

The yield power is about twice that of austenitic stainless steels, thus allowing a designer to avoid wasting weight and making the extra price aggressive when compared to 316L or 317L. At low temperatures duplex stainless steels have higher ductility than the ferritic and martensitic grades.

Technique For our stainless

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.

  • It also demonstrates good fatigue power, as well as outstanding resistance to emphasize corrosion cracking, crevice, pitting, erosion, and general corrosion in extreme environments.
  • It is the most broadly used duplex stainless steel grade and is characterised by excessive yield power, double that of the usual austenitic stainless-steel grades.
  • Duplex 2205 is a two-part, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless-steel.

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

It demonstrates good fatigue power, as well as outstanding resistance to stress-corrosion cracking, crevice, pitting, erosion and general corrosion in severe environments. Alloy 2205 duplex stainless steel plate provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steels in virtually all corrosive media. It additionally has excessive corrosion and erosion fatigue properties in addition to lower thermal expansion and better thermal conductivity than austenitic.

This allows a designer to save lots of weight and makes the alloy more price aggressive when in comparison with 316L or 317L. The physical properties of grade 2205 stainless steels are tabulated below. Duplex 2205 Stainless Steel is utilized in functions that require power and good corrosion resistance.

Strengths of duplex stainless steels can in some circumstances be double that for austenitic stainless steels. Alloy 2205 duplex stainless steel plate should be annealed at 1900°F minimal, followed by fast cooling, ideally by water quenching. This remedy applies to each resolution annealing and stress relieving. Stress reduction therapies at any lower temperature carry the risk of precipitation of detrimental intermetallic or nonmetallic phases.

Grade 2205 stainless steels are apt replacements to austenitic grades, especially in premature failure environments and marine environments. When scorching forming is required, the workpiece should be heated uniformly and labored in the vary of 1750 to 2250°F. Alloy 2205 duplex chrome steel plate is kind of delicate at these temperatures and is quickly fashioned. Immediately beneath this vary, the austenite becomes considerably stronger than the ferrite and will trigger cracking, a selected danger to “cold” edges.

The UNS designation for SAF 2205 is S31803/S32205 and the EN steel no. is 1.4462. SAF 2205 or Duplex 2205 is often used as an alternative to costly 904L chrome steel owing to comparable properties but cheaper elements. Duplex stainless steel is out there in a number of types like bars, billets, pipes, tubes, sheets, plates and even processed to fittings and flanges. Duplex 2205 chrome steel is used extensively in purposes that require good corrosion resistance and strength. The S31803 grade stainless steel has undergone numerous modifications leading to UNS S32205, and was endorsed within the year 1996.
