Stainless Steel Materials for Food - Containers
304 stainless steel is one of the most commonly used materials for food - containers. It contains approximately 18% chromium and 8 - 10.5% nickel. The chromium content forms a passive chromium - oxide film on the surface, which provides excellent corrosion resistance. It can resist the corrosion of many substances such as ordinary food acids (like citric acid in fruits and acetic acid in vinegar to a certain extent), and is suitable for a wide range of food - storage and cooking applications. For example, it's often used in high - quality stainless - steel pots and pans, as well as food - grade storage containers.
304 不锈钢
是食品容器中最常用的材料之一。它含有约 18% 的铬和 8 - 10.5% 的镍。铬含量在其表面形成一层钝化的氧化铬膜，这使其具有出色的耐腐蚀性。它能够抵抗许多物质的腐蚀，例如普通食品酸（如水果中的柠檬酸和一定程度上的醋中的醋酸），并且适用于各种各样的食品储存和烹饪应用。例如，它经常用于高品质的不锈钢锅具以及食品级储存容器。
316 stainless steel is an upgrade of 304 stainless steel. In addition to chromium and nickel, it contains about 2 - 3% molybdenum. The molybdenum element enhances its resistance to corrosion, especially in more corrosive environments such as those containing chlorides. It's highly suitable for applications where the container may come into contact with seawater - like substances (for example, some seafood - related food processing) or harsh chemicals. In the food industry, it's often used for high - end food - storage and processing equipment, like some precision - made seafood storage tanks
316 不锈钢
是 304 不锈钢的升级版。除了铬和镍之外，它还含有约 2 - 3% 的钼。钼元素增强了它的耐腐蚀性，特别是在含有氯化物等腐蚀性更强的环境中。它非常适合用于容器可能会接触到类似海水物质（例如，一些与海鲜有关的食品加工）或刺激性化学品的应用场景。在食品工业中，它经常用于高端食品储存和加工设备，如一些精密制造的海鲜储存罐。
430 stainless steel has a relatively high chromium content (around 16 - 18%) and a low carbon content. It's magnetic, which is different from austenitic stainless steel. Its corrosion resistance is not as good as 304 stainless steel, especially in more corrosive media. However, it's often used for applications where cost - effectiveness is a priority and the corrosive environment is not extremely severe. For example, it's used in some simple food - storage boxes or less - demanding food - handling utensils where the contact with corrosive substances is limited.
430 不锈钢
铬含量相对较高（约 16 - 18%），碳含量较低。它有磁性，这一点与奥氏体不锈钢不同。它的耐腐蚀性不如 304 不锈钢，特别是在腐蚀性较强的介质中。然而，它经常用于优先考虑成本效益且腐蚀环境不是极其恶劣的应用场景。例如，它用于一些简单的食品储存盒或要求不高的食品处理器具，这些器具与腐蚀性物质的接触有限。
410 Stainless Steel
410 stainless steel is a martensitic stainless steel with a relatively high carbon content. It has good hardness and strength, which makes it suitable for applications that require some mechanical strength, such as some kitchen knives. But its corrosion resistance is relatively weak compared to austenitic stainless steel. When used as a food - container, it needs to be carefully considered in terms of the types of food it will hold and the usage environment to avoid rapid corrosion. For example, it's not recommended for long - term storage of acidic foods.
410 不锈钢
是一种马氏体不锈钢，碳含量相对较高。它具有良好的硬度和强度，这使得它适合用于需要一定机械强度的应用场景，如一些厨房刀具。但是与奥氏体不锈钢相比，它的耐腐蚀性相对较弱。当它用作食品容器时，需要仔细考虑它所要盛放的食物类型和使用环境，以避免快速腐蚀。例如，不建议用它来长期储存酸性食物。
