Nickel is white-silver, usually in compound form because in its compound form it is inert with oxygen gas while in its pure form it acts on oxygen. Nickel hard, shiny and smooth, malleable and inlaid, melting at high temperatures of 1455oC, so it is applied quite a lot in life.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif; font-size: 130%;\"><img class=\"aligncenter wp-image-4459 size-large\" src=\"https:\/\/inoxdaiduong.com\/wp-content\/uploads\/2019\/11\/hinh-anh-niken-830x541.jpg\" alt=\"Ni - Nickel\" width=\"830\" height=\"541\" srcset=\"https:\/\/inoxdaiduong.com\/wp-content\/uploads\/2019\/11\/hinh-anh-niken-830x541.jpg 830w, https:\/\/inoxdaiduong.com\/wp-content\/uploads\/2019\/11\/hinh-anh-niken-220x143.jpg 220w, https:\/\/inoxdaiduong.com\/wp-content\/uploads\/2019\/11\/hinh-anh-niken-570x372.jpg 570w, https:\/\/inoxdaiduong.com\/wp-content\/uploads\/2019\/11\/hinh-anh-niken-768x501.jpg 768w, https:\/\/inoxdaiduong.com\/wp-content\/uploads\/2019\/11\/hinh-anh-niken-476x310.jpg 476w, https:\/\/inoxdaiduong.com\/wp-content\/uploads\/2019\/11\/hinh-anh-niken.jpg 1080w\" sizes=\"(max-width: 830px) 100vw, 830px\" \/><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: 'times new roman', times, serif; font-size: 130%;\">In terms of chemical properties, nickel resistant to corrosion should be applied more on anti-rust products.<\/span><\/p>\n<h3><span id=\"Are_they_really_toxic\"><span style=\"font-family: 'times new roman', times, serif; font-size: 130%;\"><b>Are they really toxic?<\/b><\/span><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: 'times new roman', times, serif; font-size: 130%;\">For health, nickel is both advantage and disadvantage . As we know, in some foods we eat every day, small amounts of nickel play a necessary role in our bodies. They participate in the metabolism, especially protein, contributing to the creation of important lipids, hormones. Nickel can be found in small amounts in nuts, beans, chocolate &#8230;<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: 'times new roman', times, serif; font-size: 130%;\">However, if tolerated or exposed to an excessive amount of nickel, it leads to nickel poisoning.

The mechanical and physical properties of steel are more stable and durable over the time thanks to the presence of nickel. In addition, it is also a factor that enhances the oxidation resistance of steel thanks to its inertness to oxygen. Therefore, stainless steel is not easily corroded by its surroundings.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: 'times new roman', times, serif; font-size: 130%;\">In stainless steel, depending on the grade of steel, the percentage of nickel may vary. The higher the percentage of nickel, the more its durability is proportional. It can be said that the great properties that stainless steel brings to our lives today cannot be without the great contribution of nickel. Nickel plays a very important role in the stainless steel manufacturing industry.<\/span><\/p>\n<p style=\"text-align: right;\"><span style=\"font-family: 'times new roman', times, serif; font-size: 130%;\"><strong>Source: Inox Dai Duong<br \/>\nVietnamese: <a href=\"https:\/\/inoxdaiduong.com\/niken-la-gi\/\">https:\/\/inoxdaiduong.com\/niken-la-gi\/<\/a><br \/>\n<\/strong><\/span><\/p>\n<div style=\"display: none;\"\n    class=\"kk-star-ratings kksr-valign-bottom kksr-align-center kksr-disabled\"\n    data-id=\"4556\"\n    data-slug=\"\">\n    <div class=\"kksr-stars\">\n    <div class=\"kksr-stars-inactive\">\n            <div class=\"kksr-star\" data-star=\"1\">\n            <div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"2\">\n            <div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"3\">\n            <div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"4\">\n            <div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"5\">\n            <div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n    <\/div>\n    <div class=\"kksr-stars-active\" style=\"width: 0px;\">\n            <div class=\"kksr-star\">\n            <div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\">\n            <div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\">\n            <div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\">\n            <div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\">\n            <div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n    <\/div>\n<\/div>\n    <div class=\"kksr-legend\">\n            <span class=\"kksr-muted\"><\/span>\n    <\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>As we all know nickel is one of the components of stainless steel, but how does it play a role in this wonderful material?
