Corrosion resistance continues to be an outstanding advantage of stainless steel flanges. However, it is also an important point.
Although carbon steel flanges have high strength and excellent plasticity and shearability, they have poor corrosion resistance, and usually show large-scale corrosion after one month of use. Extensive perforation appeared after six months. Constitute medium disclosure. Assuming the selection of stainless steel flanges: First, the quotation is more expensive. The stainless steel (ICr18Ni9Ti) flat flange is about 3-5 times that of the carbon steel flange; the second is that the welding skills are relatively high in demand, such as poor swing, it is easy to form a joint crack: the third is the currently used stainless steel The presence of titanium carbide in the steel will reduce the plasticity, resistance and stamping performance of the material. Poor use can easily cause flange cracking. Is there a flange that boils down to the excellent properties of stainless steel and carbon steel flanges.
1. The forged stainless steel flange has precise shape and size and small processing volume.
2. The advantage of casting is that it can make a relatively complex shape and the cost is relatively low.
3. Forged centrifugal stainless steel flanges are much thinner than ordinary sand forging, and the quality has improved a lot, and it is not easy to cause problems such as loose layout, pores, and trachoma.
