Stainless steel bar is an indispensable part of building materials, here we know about Hefei stainless steel bar.

Stainless steel bars made of stainless steel ingots, hot rolled or forged, can be divided into two categories according to shape and surface treatment. According to the shape, it can be divided into stainless steel round bar, stainless steel square bar and stainless steel hexagonal bar. According to the surface treatment, it can be divided into stainless steel black bar, stainless steel acid white bar, stainless steel bright bar and stainless steel grinding bar.



Stainless steel bars are divided into 2 series, 3 series and 4 series. 2 series such as 201 stainless steel bar: it belongs to Cr Ni Mn austenitic stainless steel with low magnetic property. 202 stainless steel bar: it belongs to Cr Ni Mn austenitic stainless steel with better properties than 201 stainless steel. 3 series such as 301 stainless steel bar: good ductility, used for molding products. It can also be hardened rapidly by machining. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel. 4 series such as 408 - good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni. 409 (British and American), commonly used as automobile exhaust pipe, belongs to ferritic stainless steel (chromium steel).

Stainless steel bars are mainly used in aircraft engine blades, casing, fasteners, combustion chamber, disk, shaft, combustion chamber outer wall, liquid oxygen kerosene engine, projectile body, cylinder, propulsion device, etc. It is widely used in aerospace, aviation, atomic energy, nuclear energy, petroleum, chemical industry, food, environmental protection, marine development, boiler heat exchanger and other fields.
