Quality of the obtained zinc coatings (gloss, smoothness, thickness, adherence, etc.) is different and depends on chemical composition; especially on content of carbon (C), phosphorous (P) and silicon (Si).\r\n<\/p>\r\n<p>\r\nContent of carbon and silicon in steel should not exceed 0.5% in total. In case of silicon containing steel, sometimes it happens that the iron &#8211; zinc reaction is very intense and share of the iron-zinc alloy in the coating will be higher than normal. In extreme case, zinc coating can be completely composed of iron &#8211; zinc alloy. The phenomenon (so called Sandelin effect) can be observed with content of silicon 0.03% to 0.14% and above 0.25%. In these cases, zinc coating is usually mat and grey, rough, uneven, brittle &#8211; fragile to deformation and mechanical defects. Properties of zinc coating related to chemical composition of steel are specified by PN-EN ISO 14713-2. Appearance of the hot galvanized zinc coating on different steel is presented in the below table.\r\n<\/p>\r\n\r\n<\/div>\r\n<div class=\"textwrapper ttextwrapper\">\r\n\r\n<table class=\"mstripes shad-2 is100p\">\r\n<thead>\r\n<tr>\r\n<th>Steel groups<\/th>\r\n<th>Silicon content [%]<\/th>\r\n<th colspan=\"2\">Appearance of hot galvanized zinc coating<\/th>\r\n<\/tr>\r\n<\/thead>\r\n<tbody>\r\n<tr>\r\n<td>Low-silicon<\/td>\r\n<td>up to 0,03<\/td>\r\n<td><img loading=\"lazy\" src=\"https:\/\/www.mostostal.siedlce.pl\/wp-content\/uploads\/2017\/06\/1-150x75.jpg\" alt=\"Stale niskokrzemowe\" width=\"150\" height=\"75\" class=\"alignnone size-thumbnail wp-image-558\" \/><\/td>\r\n<td>silver, glossy<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Sandelin<\/td>\r\n<td>from 0,03 to 0,14<\/td>\r\n<td><img loading=\"lazy\" src=\"https:\/\/www.mostostal.siedlce.pl\/wp-content\/uploads\/2017\/06\/2-150x75.jpg\" alt=\"Stale Sandelinowskie\" width=\"150\" height=\"75\" class=\"alignnone size-thumbnail wp-image-557\" \/><\/td>\r\n<td>grey, mat, rough, brittle<\/td><\/tr>\r\n<tr>\r\n<td>Sebisty<\/td>\r\n<td>from 0,14 to 0,25<\/td>\r\n<td><img loading=\"lazy\" src=\"https:\/\/www.mostostal.siedlce.pl\/wp-content\/uploads\/2017\/06\/3-150x75.jpg\" alt=\"Stale Sebiste\" width=\"150\" height=\"75\" class=\"alignnone size-thumbnail wp-image-560\" \/><\/td>\r\n<td>silver and glossy to mat and grey<\/td><\/tr>\r\n<tr>\r\n<td>High alloy<\/td>\r\n<td>above 0,25<\/td>\r\n<td><img loading=\"lazy\" src=\"https:\/\/www.mostostal.siedlce.pl\/wp-content\/uploads\/2017\/06\/4-150x75.jpg\" alt=\"Stale Wysokokrzemowe\" width=\"150\" height=\"75\" class=\"alignnone size-thumbnail wp-image-559\" \/><\/td>\r\n<td>mat, grey, brittle<\/td><\/tr>\r\n<\/tbody>\r\n<\/table> \r\n<\/div>\r\n\r\n","protected":false},"excerpt":{"rendered":"What steel can be galvanized?
