Inferior 2,205 stainless steel has the following four features: Reduce the profile thickness. 90 series sliding window type, according to national standards which 2,205 stainless steel wall thickness minimum of not less than 1. 4mm, Guangdong only 0. 6-0. 7mm。
2,205 deformation of duplex stainless steel, or even glass cracked peeling and other phenomena.
Inferior 2,205 stainless steel has the following four features: Reduce the profile thickness. 90 series sliding window type, according to national standards which 2,205 stainless steel wall thickness minimum of not less than 1. 4mm, Guangdong only 0. 6-0. 7mm。 46 series spring door type, minimum national standards using 2,205 stainless steel wall thicknesses is not less than 1. 62mm, through the check, some products of Guangdong only has 0.97~1.8mm.
According to the national standard. Building duplex stainless steel 2205 oxidation film thickness should be not less than 10mm.. Insufficient thickness, 2,205 surface prone to rusting and corrosion of duplex stainless steel. Some no name and address of the sampling, production permit, certification of 2,205 stainless steel,The film thickness is only 2 to 4 um.
According to expert estimates each 1um oxidation film thickness reduction, profiles can reduce electricity costs more than 150 Yuan per ton. Inferior 2,205 stainless steel significantly reduce closing time, reduce the loss of chemical reagents, cost reduction, but profile is significantly reduced corrosion resistance.(Fiona)
Chemical composition is not eligible.
Mix with a large number of complex aluminum, aluminum scrap 2,205 stainless steel can greatly reduce costs, but could cause buildings 2,205 stainless steel chemical composition is not qualified, serious threat to building security.
