A4 is equivalent to American standard 316L stainless steel and equivalent to my country's 0Cr17Ni12Mo2 stainless steel. 0Cr17Ni12Mo2 austenitic stainless steel is suitable for use in seawater and other media. It is mainly used as a pitting corrosion resistant material. It is used in photography, food industry, coastal area facilities, ropes, CD rods, bolts, nuts and other parts that require pitting corrosion resistance. superior.
A4 means: A stands for austenitic stainless steel; 4 stands for 316 stainless steel; if there are horizontal bars and numbers after A4, it represents the tensile strength data.
For example: A4-70, 70 means that the tensile strength of the standard part shall not be less than 700 N/mm2.
Generally speaking, A4-70 can be made of the following materials:
00Cr17Ni14Mo2
00Cr17Ni12Mo2
00Cr17Ni13Mo2N
00Cr17Ni14Mo3
The corrosion resistance of these materials is basically equivalent to that of 316.
