ASME UNS S31008 Stainless Steel Plate Thickness 3.0 - 16.0mm in Coill Application for Boiler
310S stainless steel plate is similar to 310 stainless steel plate. The difference is that the carbon content is lower, which can reduce carbide precipitation and improve weldability. Compared with the usual austenitic steel (such as SS 304), the nickel and chromium content of the SS 310S steel plate has soared, and it has similar corrosion resistance, higher oxidation resistance, and higher room temperature effectiveness. 310S steel plate is easy to manufacture.

Hot rolled 310s stainless steel plate has a relatively high carbon content of 0.25%, while 310S stainless steel has a low carbon content of 0.08%, and the other chemical components are identical.
Therefore, the strength and hardness of 310 stainless steel are higher and the corrosion resistance is worse. The corrosion resistance of 310S stainless steel is better and the strength is slightly lower. 310S stainless steel plate is relatively difficult to smelt due to its low carbon content, so the price is relatively high.
1. The chemical composition is 310 stainless steel. The carbon content is 0.15% and the 310S requirement is 0.08%. In addition, he also requires the MO component to be less than or equal to 0.75%.
2. Surface hardness in terms of strength. 310 stainless steel is greater than 310S stainless steel.
3. The corrosion resistance of 310S is greater than 310 because 310S adds MO.
4. The high-temperature resistance of 310S stainless steel under the same processing conditions is better than 310 stainless steel.
By definition, steel ingots or billets are difficult to deform at normal temperatures and are difficult to process. Generally, they are heated to 1100 to 1250°C for rolling. This rolling process is called hot rolling. Most steels are rolled by hot rolling. However, because the surface of the steel is prone to iron oxide scale at high temperatures, the surface of the hot-rolled steel is rough and the size fluctuates greatly.
Therefore, steel with a smooth surface, accurate size, and good mechanical properties are required, and hot-rolled semi-finished products or finished products are used as raw materials and then cold. Rolling method production.
