1.304 stainless steel plate has a beautiful surface and diverse usage possibilities, good corrosion resistance, and is longer and more durable than ordinary steel. 304 stainless steel plate has good corrosion resistance and high strength, so the possibility of using thin plates is high. It is resistant to high temperature oxidation and high strength, and therefore can withstand fire and room temperature processing, which is easy to plastic processing. Because there is no need for surface treatment, it is simple, easy to maintain, clean, and has high smoothness and good welding performance.
2.The main difference in chemical composition between 316 and 304 is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance and is more resistant to corrosion than 304 in high-temperature environments. So in high-temperature environments, engineers generally choose 316 material components. But everything is absolute. In a concentrated sulfuric acid environment, no matter how high the temperature is, do not use 316. We know that in order to prevent thread bite under high temperatures, a black solid lubricant needs to be applied.
3.Due to the high yield point and hardness of 304 stainless steel itself, the cold work hardening effect is significant. When bending 304 stainless steel plates, their characteristics are as follows: due to poor thermal conductivity and low elongation compared to ordinary low-carbon steel, the required deformation force is large; Stainless steel sheet has a strong rebound tendency compared to carbon steel during bending; Stainless steel plates have a lower elongation compared to carbon steel, and the bending angle R of the workpiece during bending is greater than that of carbon steel, otherwise there is a possibility of cracking; Due to the high hardness of 304 stainless steel plate, the cold work hardening effect is significant. Therefore, when selecting bending tools, Tool steel with heat treatment hardness of more than 60HRC should be selected. Its surface roughness is one order of magnitude higher than that of carbon steel bending tools
