Product Description

Mill Certificate Duplex 2B 2205 2507 Stainless Steel Coil​ 



HAOSTEEL GROUP CO., LIMITED has different material grades of stainless steel coil, provide very comprehensive stainless steel products for you, you can find the complete specifications, the quality of the products with high performance and high quality, and can be tailored, if you need more product information, including automotive, petrochemical, electronics and pharmaceutical, and stainless steel products manufacturers, such as building suppliers and general engineering company, in order to meet the various needs.


Duplex stainless steel has the characteristics of both austenitic stainless steel and ferritic stainless steel.The yield strength can reach 400Mpa ~ 550MPa, 2 times that of ordinary austenitic stainless steel.Compared with ferritic stainless steel, biphasic stainless steel has high toughness, low brittle transition temperature and improved intercrystalline corrosion resistance and welding performance.At the same time retain the some characteristics of ferritic stainless steel, such as 475 ℃ brittleness, high thermal conductivity, small linear expansion coefficient, superplasticity and magnetism, etc.Compared with austenitic stainless steels, two-phase stainless steels have higher strength, especially higher yield strength, and their properties such as resistance to pore corrosion, stress corrosion and corrosion fatigue are also improved.


Duplex stainless steel 2205 is composed of 21% chromium,2.5% molybdenum and 4.5% ni - n alloy.It has high strength, good impact toughness and good overall and local resistance to stress corrosion.The yield strength of the 2205 duplex stainless steel is twice that of the austenitic stainless steel, a feature that allows the designer to reduce weight when designing the product, giving the alloy a price advantage over the 316,317 L.This alloy is particularly suited to - + 50 ° F / 600 ° F temperature range.
