Product Description
The most common variety in the 300 series is 304. If you want to judge the trend of the entire stainless steel price, you can change it according to the price of 304. The 400 series does not contain nickel, the 200 series contains less nickel, and the 300 series contains the most nickel, so the 300 series is most affected by nickel prices.
300 series can be simply divided into 304, 304L, 309S, 310S, 316, 316L, 321 and so on. The basis for the distinction is that stainless steels with different contents of various metal elements have different characteristics. The ones with L represent low carbon. The difference between 304 and 304L lies in the different content of carbon, which is also called low carbon steel. The same is true for 316 and 316L.
300 Series - Chromium-Nickel Austenitic Stainless Steels
301—Good ductility, used for molded products. Machine speed hardening is also possible. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
302-corrosion resistance is the same as 304, because the carbon content is relatively high and the strength is better.
303—By adding a small amount of sulfur and phosphorus to make it more machining.
304—that is, 18/8 stainless steel. The GB grade is 06Cr19Ni10.
309—has better temperature resistance than 304.
316—After 304, the second most widely used steel grade, mainly used in the food industry and surgical equipment, adding molybdenum to obtain a special structure that is resistant to corrosion. Because of its better resistance to chloride corrosion than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery units. Grade 18/10 stainless steels generally also meet this application level.
Model 321—Similar to 304 except that the risk of corrosion in material welds is reduced due to the addition of titanium.

Production Process
According to the production process, stainless steel bars can be divided into three types: hot rolling, forging and cold drawing. The specification of hot rolled stainless steel round bar is 5.5-250 mm. Among them: 5.5-25mm small stainless steel round bars are mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25mm are mainly used for the manufacture of mechanical parts or as seamless steel pipe billets .
