304 stainless steel plate has beautiful surface and diversified use possibilities, good corrosion resistance, and is more durable than ordinary steel. 304 stainless steel plate has good corrosion resistance and high strength. Fire-resistant normal temperature processing, that is, easy plastic processing, because no surface treatment is required, so it is simple, easy to maintain and clean, high finish and good welding performance.
The main difference between 316 and 304 in chemical composition 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. Therefore, in high temperature environments, engineers generally choose parts made of 316 materials. But the so-called thing is not absolute, in the concentrated sulfuric acid environment, do not use 316 no matter how high the temperature is, we know that in order to prevent the thread from being seized under high temperature, a dark solid lubricant needs to be applied.
Due to the high yield point and high hardness of 304 stainless steel itself, the cold work hardening effect is significant, and the characteristics of 304 stainless steel plate are as follows when bending: because the thermal conductivity is worse than that of ordinary low carbon steel, the elongation is low, resulting in a large deformation force; Compared with carbon steel, stainless steel sheet has a strong rebound tendency when bending; due to the low elongation of stainless steel sheet compared with carbon steel, the bending angle R of the workpiece during bending should be larger than that of carbon steel, otherwise cracks may appear; Due to the high hardness of 304 stainless steel plate, the cold work hardening effect is significant, so when selecting the bending tool, it is necessary to choose a tool steel with a heat treatment hardness of 60HRC or more, and its surface roughness is an order of magnitude higher than that of carbon steel bending tools.
