Stainless Steel Square Bar-2205

According to the production process, stainless steel rods can be divided into three types: hot rolling, forging and cold drawing. The specification of hot rolled stainless steel round bar is 5.5-250 mm. Among them: 5.5-25mm small stainless steel round bars are mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25mm are mainly used for the manufacture of mechanical parts or as seamless steel pipe billets .

2205 is austenitic stainless steel, its properties are very similar to 304, but due to the addition of metal titanium, it has better resistance to grain boundary corrosion and high temperature strength. Due to the addition of metallic titanium, it effectively controls the formation of chromium carbide.

2205 is austenitic stainless steel. This type of steel has the characteristics of both austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and resistance, no room temperature brittleness, and the intergranular corrosion resistance and welding function are significantly improved. At the same time, it also maintains the 475 ℃ brittleness and high thermal conductivity of ferritic stainless steel, and has the characteristics of superplasticity.

Compared with austenitic stainless steel, the strength is high and the resistance to intergranular corrosion and chloride stress corrosion is significantly improved. 2205 stainless steel plate has excellent pitting corrosion resistance and is also a nickel-saving stainless steel.
Combining many of the beneficial properties of both ferritic and austenitic steels, 2205 is the most widely used duplex stainless steel grade. Its high chromium and molybdenum content gives the stainless steel excellent corrosion resistance. The microstructure provides resistance to stress corrosion cracking and ensures high strength.
The grade is generally not suitable for use at temperatures above 300oC or below -50oC because of reduced toughness outside this range.
You are most likely to encounter 2205 stainless steel being used in industrial environments such as petrochemical, chemical, oil, gas and paper plants.
