How to identify the true and false of the 304 stainless steel belt plate

Because it is hard to identify with the naked eye material 304 stainless steel belt, so there will be some unscrupulous businessmen in other material as 304 sold to consumers, resulting in damage to the client not only, also hindered the healthy development of the industry market. 201 because of its cheaper price, yet in many economically backward villages and towns. But as people living standard rise, have further request for safety and resistance to rust, so 304 is the trend of The Times, universal access to future is just a matter of time. 304 stainless steel plate surface is beautiful and the use of diversification possibility, corrosion resistant performance is good, than ordinary steel long durable, 304 stainless steel with good corrosion resistance of high strength, and therefore the possibility of using big plate, high temperature oxidation resistance and high strength, thus able to fight fire room temperature processing, plastic processing, namely easy because need not surface treatment, so simple, simple maintenance, cleaning, finish high welding performance is good. 316 and 304 on the chemical composition of the main difference is that contains 316 Mo, and generally accepted, the 316 has better corrosion resistance, more than 304 under the environment of high temperature corrosion resistance. So under the environment of high temperature, 316 engineers typically select material components. But no absolute, the so-called things under the environment of sulfuric acid, high temperature also don't use 316 again, we know that in order to prevent thread below high temperature circumstance bite dead, need to apply a black solid lubricant. 304 due to the high yield point, stainless steel with high hardness, cold work hardening effect significantly, 304 stainless steel plate bending its characteristics as follows: because of poor thermal conductivity than normal low carbon steel, low elongation, lead to the deformation force; Compared with carbon steel stainless steel plate in bending has strong springback tendency; Stainless steel with relative to the carbon steel because of the low elongation, artifacts when bending corner R than carbon steel, or you may appear crack; Because of 304 stainless steel with high hardness, cold work hardening effect significantly, therefore when choosing bending tool to choose heat treatment hardness should reach more than 60 HRC tool steel, the surface roughness is an order of magnitude higher than carbon steel bending tools.
