316 stainless steel and 304 stainless steel difference is: different uses, different corrosion resistance, different prices.
1, the use of different:
304 and 316 have reached the food grade, but 304 stainless steel is usually used for our home appliances and home containers, 316 stainless steel is generally due to the production of medical equipment tools. Our home containers up to 304 is enough, so if the merchant says his containers are 316 that is fooling you.

2, corrosion resistance is different:
The two materials of stainless steel corrosion resistance are almost the same, but the 316 in the 304 based on the molybdenum to increase the corrosion resistance, so when encountered with a higher content of chlorine ions 316 corrosion resistance is better.

3, the price is different:
316 stainless steel has added molybdenum and nickel, while the 304 stainless steel is not, and thus 316 stainless steel prices will be a little higher than the price of 304.
Common stainless steel materials are:
1, 201 stainless steel, is one of the 300 series stainless steel, with acid resistance, alkali resistance, and density are relatively high.
2, 202 stainless steel, is a low nickel and high manganese stainless steel material, commonly used in shopping centers, or municipal engineering.
3, 301 stainless steel, is a stable austenitic stainless steel, its rust resistance is better, with more complete austenitic organization.
4, 303 stainless steel, is an easy to cut stainless steel, acid-resistant type of steel, can be used for automatic bed, bolts, and nuts.
5, 304 stainless steel, which has the processing performance is relatively good, and comprehensive performance is relatively proud, is a general-purpose type of stainless steel.
6, 304L stainless steel, is called low carbon stainless steel. With the comprehensive performance is superior.
7, 316 stainless steel, is austenitic stainless steel, internal is containing Mo element, agent of high temperature resistance, corrosion resistance is better, can be used in pipeline, dyeing equipment.
