ASTM A240 S32205 S31803 2205 Duplex Stainless Steel Plate Hot Rolled 20*2000* 6000mm

ASTM A240 Duplex 2205 2507 Stainless Steel Plate 0.6 - 50.0mm SS Plate

Product description

This gives duplex stainless many of the perks of austenitic and ferritic families of steel while also minimizing the weaknesses.

As with other families of stainless, the exact metallurgic composition of the steel varies by grade, though common components include:

• Carbon
• Manganese
• Silicon
• Chromium
• Nickel
• Phosphorous
• Sulphur

Molybdenum, nitrogen, and copper may also be used to further influence characteristics of the final product.

BENEFITS OF DUPLEX STAINLESS STEEL

While duplex stainless steel only comprises a small percentage of the global stainless steel market, it has a range of benefits when compared to traditional austenitic stainless steel and ferritic stainless steel grades.

• Improved Strength

  Many duplex grades are as much as two-times stronger than austenitic and ferritic stainless steel grades.

• High Toughness and Ductility

  Duplex stainless steel is often more formable under pressure than ferritic grades and provides greater toughness. Though they often offer lower values than austenitic steels, the unique structure and characteristics of duplex steel often outweigh any concerns.

• High Corrosion Resistance

  Depending on the grade in question, duplex stainless steels offer comparable (or better) corrosion resistance as common austenitic grades. For alloys with increased nitrogen, molybdenum, and chromium, steels exhibit high resistance to both crevice corrosion and chloride pitting.

• Cost Effectiveness

  Duplex stainless steel offers all of the above benefits while requiring lower levels of molybdenum and nickel. This means that it is a lower-cost option than many traditional austenitic grades of stainless steel.The price of duplex alloys is often less volatile than other steel grades making it easier to estimate costs -- both at an upfront and lifetime level.The higher strength and corrosion resistance also means that many parts made using duplex stainless can be thinner than their austenitic counterparts providing lower costs.

BEST USES FOR DUPLEX STAINLESS STEEL

Due to their excellent corrosion resistance, increased strength, and affordable pricing, duplex stainless steels are popular in a variety of industries and markets, including:

• Offshore and near-shore operations such as oil drilling, desalination, water treatment, and other industrial operations
• Chemical and liquid processing
• Naval parts and components
• Pollution control equipment
• Pulp and paper production
• Construction
• Hot water and brewing tanks
