Our Grades

Reduce friction by sustaining the gadget extension as brief as attainable. For duplex stainless-steel, the corrosion resistance high quality in all stainless steel plates and sheets is considerably larger. The sheets and plates of duplex steel are of magnetic power and can clearly be distinguished from the opposite chrome steel courses due to this function.

Specification Sheet Overview

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

Stress relieving just isn’t required or really helpful; however, if it must be carried out, the material ought to receive a full solution anneal at 1900°F minimum, adopted by fast cooling or water quenching. Alloy 2205 duplex stainless-steel plate combines excessive power and high corrosion resistance to provide high corrosion fatigue power.

  • SA 240 Duplex 2205 Plate is a type of stainless-steel that is graded as duplex.
  • Duplex stainless steels like 2205 typically maintain good weldability of their thickest elements, and they are much extra resistant than ordinary austenitic steels to stress corrosion cracking.
  • Duplex is a grade that’s derived by the addition of ferrite and austenitic metallic phases in equal quantities.
  • Duplex 2205 Plate suppliers supply the material in different types and shapes.
  • So the alloy is stronger and more durable than the usual austenitic steel varieties.
  • The Duplex 2205 Plate is three% molybdenum, 22% chromium, 5-6% nickel alloyed stainless-steel plate, with high-stress resistance traits, excessive power, and glorious resistance to impression.

Applications in which processing equipment is topic to each an aggresively corrosive enviroment and to cycle loading can profit from the properties of 2205 duplex chrome steel plate. Because of its excessive Stainless steel manufacturer chromium (22%), molybdenum (three%), and nitrogen (0.18%) contents, the corrosion resistance properties of 2205 duplex chrome steel plate are superior to that of 316L or 317L in most environments.

When hot forming is required, the workpiece must be heated uniformly and worked within the vary of 1750 to 2250°F. Alloy 2205 duplex stainless-steel plate is sort of delicate at these temperatures and is readily fashioned. Immediately beneath this vary, the austenite becomes considerably stronger than the ferrite and will cause cracking, a particular danger to “cold” edges. Below 1700°F there can be rapid formation of intermetallic phases because of the mixture of temperature and deformation. Whenever sizzling forming is completed, it must be adopted by a full resolution anneal at 1900°F minimum and fast quench to revive part balance, toughness, and corrosion resistance.

2205 Stainless steel sheet

SA 240 Type 2205 Duplex Stainless Steel Plate is used in marine functions the place chloride ion focus is higher. SA 240 TP 2205 Stainless Steel Plate is utilized in effluent scrubbing techniques and in biofuel crops. 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 more durable than commonplace austenitic steels. Duplex stainless steels like 2205 also preserve good weldability in their thickest sections, and they are much extra resistant to stress corrosion cracking than normal austenitic steels.
