Duplex Stainless Steel Sheet

Also known as duplex stainless steel it has twice the strength of 316 stainless steel.

Duplex stainless steel sheet.

Duplex grades duplex stainless steels are extremely corrosion resistant work hardenable alloys. This gives duplex stainless many of the perks of austenitic and ferritic families of steel while also minimizing the weaknesses. The duplex micro. Duplex stainless steel sheet is very much resistant to chloride iron corrosion and therefore localized and uniform corrosions.

Duplex stainless steels are extremely corrosion resistant work hardenable alloys. Most applications of duplex stainless steels require relatively simple forming such as the rolling of cylindrical sections press forming and vessel and tank head forming by pressing or rolling. Their microstructures consist of a mixture of austenite and ferrite phases. While exact ratios vary by grade most duplex steels have a structure that is roughly 50 percent austenite and 50 percent ferrite.

Duplex stainless steels get their name from their two phase microstructure. Duplex stainless plate sheet 2101 duplex is a lean alloyed duplex stainless grade that has approximately equal parts austenite and ferrite. 2205 stainless steel resists cracking even when faced with a combination of tensile stress corrosive chemicals and heat. Duplex stainless steel plate brown mcfarlane holds a comprehensive stock of duplex stainless steel plate in material grades s31803 s32205 and 1 4462 manufactured by western european steel makers and third party certified to en 10204 3 2.

Use it for high pressure applications in caustic environments. Duplex stainless steel plate contains relatively high levels of chromium between 18 and 28 and low to moderate amounts of nickel between 1 5 and 8. Duplex stainless plate sheet specialty steel co. It is the most widely used duplex stainless steel grade and is characterized by high yield strength double that of the standard austenitic stainless steel grades.

Duplex 2205 is a two phase ferritic austenitic 22 chromium 3 molybdenum 5 to 6 nickel alloyed stainless steel. As a result duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. All plates in stock are also certified in accordance with norsok mds d45. The material is also known as astm a240 duplex sheet because it is covered by the astm a240 standard.

Ferritic austenitic stainless steel also referred to as duplex stain less steels combine many of the beneficial properties of ferritic and austenitic steels.
