随着生活水平的提高,人们对家居品质的追求也越来越高,对厨房用具的选择也不再仅仅局限于实用性,而是开始注重其耐用性、美观性和卫生安全。其中,不锈钢作为一种耐腐蚀、高强度、轻便且易于清洁的金属材料,在现代厨房中得到了广泛应用。
然而,不锈钢并非所有类型都适合用于生产餐具和厨具。不同种类的不锈钢具有不同的性能特点,因此在选择时需要根据具体需求进行甄别。在了解不锈钢种类之前,我们首先要明确什么是“不锈钢”。
什么是“不锈钢”?
“不锈steel”这个术语源自它的一个主要特征,即该金属不会因与空气中的水分反应而生锚,这一过程称为碳化或氧化。当某些金属(如铁)暴露在含有氧气或水蒸气的大气环境中,它们会形成一个薄层保护膜,这个膜可以阻止进一步损害,但通常这只是暂时性的。一旦这个保护膜被破坏,剩下的金属就会继续腐蚀。而相比之下,“无刃”的名称意味着这些物体不会像常规刀片那样迅速损坏。
不同类型的 Stainless Steel
304 Stainless Steel - 这是一种最常用的Stainless Steel类型,其化学成分包括18%至20%铬(Cr)、8%至10.5%镍(Ni)、2%至3%钛(Ti)以及小量其他元素,如碳(C)。这种Steel拥有良好的抗腐蚀性能,并且容易热处理以改变其硬度。此外,由于它含有较低比例的镍,它比含有更高镍比例的一些Steel更加经济。因此,该Steel经常用于食品加工设备、建筑结构以及各种工业设备。
316 Stainless Steel - 这种Steel添加了更多的是氮(N)以增强抗疲劳能力。这使得它成为一种更坚固,更耐久、一般来说成本稍高一些但提供更多优点版本之一。虽然它们之间有一些微妙差异,但两者都是非常流行并广泛使用在许多应用中,其中包括海洋环境中的建筑结构,因为它们能够抵御盐雾侵袭。
410 Stainless Steel - 这是一种低碳型Stainless Steel,其化学成分主要由12-14%铬组成,以及小部分钛元素。这款产品由于其成本效益较好,而且还具有很好的表面光泽,所以经常被用于手工制品和烹饪工具等领域。但值得注意的是,它没有足够多的地面保护层,因此可能需要定期油漆,以保持其防护效果。
403, 409, 410系列 - 这些系列包含了一些特殊设计为耐候性优良型碳素化合金 steel 的产品,比如400系列内涵了三款:403, 409 和410。此类steel 对温度变化表现出极佳稳定性,同时也能抵御极端条件下的变形,从而适合那些要求长期承受严苛环境条件的地方,如车辆底盘部件或者其他承受高速冲击力的地方。
321 and 347 SS types: 在上述任何一种情况下,一些额外添加可进一步改进SS performance;例如增加0-1/2 % niobium (Nb) 或 ti (Ti) 可以减少intergranular corrosion risk。
17-4PH and other precipitation hardening grades: These are high-strength alloys that are hardened by heat treatment after fabrication.
Other grades: There are many other specialized stainless steel grades available for specific applications.
Why Choose Specific Type of Stainless Steel for Kitchen Utensils?
Kitchen utensils need to be durable enough to withstand frequent use while maintaining their hygiene standards throughout the process of food preparation and cooking.The choice of a particular type of stainless steel depends on several factors including cost, durability, resistance to corrosion as well as ease in cleaning.
The most common used type is the #304 or #18/8 stainless steel which has a good balance between strength and affordability but it does not have any nickel content which can cause allergies in some people; The higher-nickel grade known as #18/10 is also widely used but more expensive than the lower nickel grade due to its better properties such as rust resistance with less chance of pitting corrosion from acidic foods like tomatoes or citrus fruits; For example if you live near an ocean area where there's saltwater exposure then you would want to choose a higher-grade material like #316L because it resists pitting caused by chlorides better than the lower grades do.
In conclusion when choosing kitchen utensils made from different types of stainless steels one must consider factors such as durability strength resistance against corrosion ease in cleaning along with personal preferences based on budget needs etc., so they can make informed decisions about what kind best suits them best before making purchase decision at home stores or online retailers selling these items worldwide today!
