310s hot rolled stainless steel plate

310s hot rolled stainless steel plate

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.

Corrosion Resistance of 310S Hot Rolled Stainless Steel Plate:
  • Provides excellent corrosion resistance
  • High chromium content for good water resistance
  • Excellent resistance at room temperature, and also good resistance to oxidation and carburizing atmospheres
Heat Resistance of 310S Stainless Steel Plate:
  • It has good oxidation resistance when used intermittently in the air, and the temperature is as high as 1040°C and 1150°C when used continuously.
  • Good resistance to thermal fatigue and cyclic heating.
  • It is widely used in places where sulfur dioxide gas is encountered at high temperatures.
  • If subsequent water resistance is required, continuous use within the range of 425-860°C is not recommended because carbide precipitation
Simple description about 310 and 310s Stainless Steel Plate

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.

      The differences are summarized as follows:

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 310S stainless steel of the same processing conditions is better than 310 stainless steel.

Some more differences between hot rolled and cold rolled 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 temperature, 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.

Hot Rolled Stainless Plate

Rolling at normal temperature is generally understood to be cold rolling. From a metallographic point of view, the limits of cold rolling and hot rolling should be distinguished by recrystallization temperature. That is, the rolling lower than the recrystallization temperature is cold rolling, and the rolling higher than the recrystallization temperature is hot rolling. The steel has a recrystallization temperature of 450 to 600 °C.

Cold Rolled Stainless Sheet

310 stainless steel plate

Hot rolling, as the name suggests, has a high temperature of the rolled piece, so the deformation resistance is small and a large amount of deformation can be achieved. Taking the rolling of the steel sheet as an example, the thickness of the continuous casting blank is generally about 230 mm, and after rough rolling and finish rolling, the final thickness is 1 to 20 mm.

At the same time, due to the small width-to-thickness ratio of the steel plate, the dimensional accuracy requirement is relatively low, and the shape problem is not easy to occur, and the convexity is mainly controlled. For the requirements of the organization, it is generally achieved by controlled rolling and controlled cooling, that is, controlling the rolling temperature, finish rolling temperature, and crimping temperature of the finishing rolling to control the microstructure and mechanical properties of the strip.

Cold rolling, generally there is no heating process before rolling. However, due to the small thickness of the strip, the shape of the plate is prone to occur. Moreover, after cold rolling, it is a finished product, and therefore, in order to control the dimensional accuracy and surface quality of the strip, many complicated processes are employed. The cold rolling production line is long, the equipment is numerous, and the process is complicated.

As the user’s requirements for dimensional accuracy, shape, and surface quality of the strip are improved, the control model, L1 and L2 systems, and the shape control means of the cold rolling mill are relatively hot. Moreover, the temperature of the rolls and strip is one of the more important control indicators.

The cold rolled product and the hot rolled product sheet are different from the previous process and the next process. The hot rolled stainless steel product is the raw material of the cold rolled product, and the hot rolled steel coil is machined by the pickling process. Rolling mills, rolling, are cold-formed, mainly to roll thick-form hot-rolled sheets into thin-gauge cold-rolled sheets, usually 0.3-0.7mm by hot-rolling on-board rolling of 3.0mm. Cold rolled coil, the main principle is to use the extrusion principle to force deformation.
