Many people do not know what kind of material to choose when buying flanges, you like stainless steel flange has 304, 316 and other materials, carbon steel flange has 20 steel, 45 steel, Q235 and so on, as the manufacturer today to tell you about our common 304 flange and carbon steel flange difference.
304 flange
304 flange and carbon steel flange difference (characteristics, use)
304 flange is a kind of stainless steel flange, that is, 0Cr18Ni9, belongs to the comprehensive performance is good, so the amount of the market is relatively large, carbon steel flange the same market share is relatively high, but they can not replace each other, 304 has the characteristics of corrosion resistance, no rust, and carbon steel flange encounter water or humid air, easy to rust, In order to reduce the service life, so you need to use stainless steel can not use carbon steel, such as many chemical plants pharmaceutical and other fields for stainless steel, transport some sand and stone can use carbon steel, sometimes also have to look at the cost of the budget, the price gap between the two is relatively large.
304 flange and carbon steel flange difference (test, manufacturer)
304 flange and carbon steel flange in the manufacturer’s view of the production process is basically the same, nothing more than forging, plate cutting and rolling, but in order to ensure the quality of the material and product, the detection methods used are not the same, such as the detection of carbon steel flange whether there are pores and cracks, the use of ultrasonic detection on the line, and used in 304 flange is not so sensitive, Rolled carbon steel or stainless steel large diameter flange have weld, stainless steel material needs to be used to detect more accurate, requirements are not strict large carbon steel flange can be used ultrasonic.
summarize
The difference between 304 flange and carbon steel flange is really very obvious, so the customer should plan according to the cost and use situation, but for our manufacturer, which kind of flange can guarantee the quality and quantity of delivery, commonly used specifications of flange and a large number of spot, can effectively reduce the delivery cycle. The important thing is that the after-sales service is timely.
