However, nickel is an expensive metal, which increases the production cost of SS316 stainless steel.<\/p>\n\n\n\n<p>This is why SS316 Shower Hardware is usually more expensive than SS304 products.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-can-a-magnet-test-stainless-steel-material\">Can a Magnet Test Stainless Steel Material?<\/h2>\n\n\n\n<p>Many people believe stainless steel can be identified using a magnet. In fact, this method is not accurate.<\/p>\n\n\n\n<p>During the manufacturing and processing of Shower Door Hardware products, stainless steel may develop slight magnetic properties after cutting, bending, polishing, or welding.<\/p>\n\n\n\n<p>Therefore:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>SS304 can show magnetism<\/li>\n\n\n\n<li>SS316 can also show slight magnetism<\/li>\n<\/ul>\n\n\n\n<p>Using a magnet alone cannot accurately determine the material grade.<\/p>\n\n\n\n<p>How to Verify SS304 or SS316 Material?<\/p>\n\n\n\n<p>The most reliable method is spectrum testing.<\/p>\n\n\n\n<p>Customers can send a product sample to a professional testing institution for stainless steel material analysis.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Standard Material Testing<\/h3>\n\n\n\n<p>A normal spectrum test usually costs around:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>USD 20 per test<\/li>\n<\/ul>\n\n\n\n<p>This report is already sufficient for most business and commercial projects.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Professional Certification<\/h3>\n\n\n\n<p>Some engineering projects may require more formal certification documents.<\/p>\n\n\n\n<p>Professional certification reports may cost:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Around USD 200 or more<\/li>\n<\/ul>\n\n\n\n<p>The testing results are basically the same.
