Type 201 stainless steel is an austenitic chromium-nickel-manganese stainless steel, which is developed to save nickel. Type 201 is a low-cost alternative to traditional Cr-Ni stainless steels such as 301 and 304. The nickel is replaced by added manganese and nitrogen. It cannot be hardened by heat treatment, but can reach high tensile strength by cold working. Type 201 is essentially non-magnetic in the annealed condition and becomes magnetic upon cold working. In many applications, the 201 type may replace the 301 type.
304 stainless steel is a kind of universal stainless steel material, rust resistance than 200 series of stainless steel material is stronger. High temperature resistance is also better, can be as high as 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it is concluded in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of less than or equal to 65% of the boiling temperature. It also has good corrosion resistance to alkali solution and most organic and inorganic acids.
ASTM A335 steel pipe may be hot finished or cold drawn and subjected to the following finishing heat treatment. The specification covers "chrome-molybdenum" seamless pipes with excellent corrosion resistance and high temperature tensile strength. Generally, ASTM A335 P11, P22, and P91 pipelines are used for power generation and downstream oil and gas, and P5 and P9 grades are used for refinery applications.
DIN 17175 is suitable for seamless pipes and is used in the construction of boilers, pipelines, pressure vessels and equipment. The maximum temperature can reach 600 ℃. At the same time, under high pressure, the total stress and related fouling conditions can increase or decrease the temperature limit.
