304 and 316 are extended in 304 and 316 respectively, and the respective grades are as follows:
304 is 06Cr19Ni10, 304L is 00Cr19Ni10;
316 is 0Cr17Ni12Mo2, and 316L is 00Cr17Ni14Mo2.
304 stainless steel is a versatile stainless steel material. It has a wide range of functions. Food equipment, general chemical equipment, atomic energy industrial equipment, etc., have excellent corrosion resistance and molding properties.
316 stainless steel is a kind of hollow long round wire, which is widely used in industrial transportation pipelines such as petroleum, chemical, medical, food, light industry, mechanical instrumentation and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also used to produce a variety of conventional weapons, barrels, shells and so on.
