high-temperature resistance, strength, and other characteristics make it unique in many areas, however, stainless steel is not a piece of iron, it is divided into a variety of types, each type has its unique composition and properties.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_81 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div

stainless steel is the most widely used type of stainless steel, its chromium content is generally more than 16%, and nickel content is more than 1%. This stainless steel has good corrosion resistance, heat resistance, and welding performance, and has good plasticity and toughness. Common austenitic stainless steel is 201, 304, 316, and so on.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>201 stainless steel: Containing low nickel and manganese, relatively poor corrosion resistance, but more affordable, mainly used for home and decoration.<\/li>\n\n\n\n<li>304 stainless steel: Containing about 8% nickel, it has good corrosion resistance, high-temperature resistance, and welding performance, and it is the preferred material for food, medical, and other fields.<\/li>\n\n\n\n<li>316 stainless steel: molybdenum is added based on 304 stainless steel, which makes it have better corrosion resistance and heat resistance, and it is especially suitable for marine environments, chemical equipment, and other fields.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Ferritic_Stainless_Steel\"><\/span>Ferritic Stainless Steel<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ferritic stainless steel to ferrite as a matrix, its chromium content is generally greater than 12%, and the nickel content is lower. This stainless steel&#8217;s strength and hardness are high, but the toughness is relatively poor, and corrosion resistance is not as good as austenitic stainless steel. Common ferritic stainless steel 409, 430, and so on.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>409 stainless steel: mainly used in automobile exhaust systems water heaters, etc., has a certain degree of corrosion resistance and high-temperature oxidation resistance.<\/li>\n\n\n\n<li>430 stainless steel: high chromium content, good corrosion resistance, and magnetic, commonly used in kitchen equipment, and decorative materials.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Martensitic_Stainless_Steel\"><\/span>Martensitic Stainless Steel<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In martensitic stainless steel to martensite as a matrix, chromium content is generally more than 12%, and nickel content is lower. This kind of stainless steel&#8217;s strength and hardness are high, but poor toughness, and poor welding performance. Martensitic stainless steel is mainly used in areas requiring high hardness and resistance, such as cutting tools and bearings.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>410 stainless steel: it is the most common martensitic stainless steel, suitable for the manufacture of cutting tools, springs, and so on.<\/li>\n\n\n\n<li>440C stainless steel: has high hardness and wear resistance, commonly used in demanding surgical blades, bearings, etc\u2026<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Is_Stainless_Steel_304_Safe\"><\/span>Is Stainless Steel 304\u00a0Safe?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">304 stainless steel, also known as 18\/8 stainless steel, contains about 18% chromium and 8% nickel, which provides better corrosion resistance, wear resistance, high-temperature resistance, and beautiful appearance. Among the many types of stainless steel, 304 stainless steel is one of the most widely used because of its stable performance and moderate price.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Low_Metal_Element_Precipitation\"><\/span>Low Metal Element Precipitation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">304 stainless steel releases minimal amounts of chromium and nickel during cooking, far below international food safety standards, making it safe for food contact.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Safe_Chromium_Content\"><\/span>Safe Chromium Content<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Chromium in 304 stainless steel exists mainly as trivalent chromium, which is non-toxic and beneficial to the body. Toxic hexavalent chromium is not present under normal use.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Nickel_Safety\"><\/span>Nickel Safety<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Nickel in 304 stainless steel is in a metallic form that does not cause allergic reactions. Nickel compounds, which may cause allergies, are absent.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Antibacterial_Properties\"><\/span>Antibacterial Properties<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">304 stainless steel has natural antibacterial properties, as its metal components can damage bacterial cell walls, inhibiting growth and making it ideal for kitchen use.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Ensure_the_Safety_of_304_Stainless_Steel\"><\/span>How to Ensure the Safety of 304 Stainless Steel<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Correct_Purchase_of_Stainless_Steel_Products\"><\/span>Correct Purchase of Stainless Steel Products<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When consumers buy stainless steel products, they should choose formal channels and well-known brands to ensure that the products comply with national food safety standards.
