304不锈钢板 1.0*1240冷轧2B精密剪切分条分卷加工彩色装饰板
什么是不锈钢，最为通俗的来说，就是要求含铬（Cr）量大于11%的铁基合金。不锈钢的抗生锈性源于合金中铬的存在，铬形成钝化膜，保护底层材料免受腐蚀。以常见的304材料为例，其对应的国标旧牌号为0Cr18Ni9，这里铬的含量就是18%。下面红线是大气中的腐蚀速率，大约在铬大于10%之后，腐蚀速率才是可以接受的。What is stainless steel, the most popular speaking, is required to contain chromium (Cr) more than 11% of the iron-based alloy. The rust resistance of stainless steel stems from the presence of chromium in the alloy, and the chromium forms a passivation film to protect the underlying material from corrosion. Take the common 304 material as an example, the corresponding national standard old brand number is 0Cr18Ni9, where the content of chromium is 18%. The red line below is the rate of corrosion in the atmosphere, which is acceptable after chromium is greater than 10%.不锈钢不是不会生锈的钢铁，而是不容易生锈的钢铁，它的标准就是里面有没有一定量的铬金属。一般来说，铬含量在10.5%以上的钢铁就属于不锈钢了。Stainless steel is not the steel that will not rust, but is not easy to rust steel, its standard is whether there is a certain amount of chromium metal inside. Generally speaking, the chromium content in more than 10.5% of the steel belongs to stainless steel.304不锈钢是得到较为广泛应用的不锈钢、耐热钢。用于食品生产设备、昔通化工设备热交换器冷凝器、核能等。304 stainless steel is a more widely used stainless steel, heat-resistant steel. Used in food production equipment, Xitong chemical equipment heat exchanger condenser, nuclear energy, etc.选择不锈钢产品和选择铁锅是一样的，应该尽可能认准正规品牌和大公司，避免一些不法商贩选择劣质产品以次充好。对于消费者来说，尤其不要贪小便宜购买低价产品。The choice of stainless steel products and the choice of iron pot is the same, should be as far as possible to look for the regular brands and large companies, to avoid some illegal vendors choose inferior products shoddy. For consumers, especially do not greed small cheap to buy cheap products.在这一方面，我还是比较推荐佛山市万庆物资有限公司销售的不锈钢。他们公司从2014年成立，经过十年的经营，发展成为了集板材、管材、型材等销售为一体的大型不锈钢销售厂商，多项产品被广泛用于医药、食品和酒厂等行业，质量有保证。In this respect, I still recommend Foshan Wanqing Materials Co., Ltd. sales of stainless steel. Their company was established in 2014, and after ten years of operation, it has developed into a large stainless steel sales manufacturer integrating plate, pipe and profile sales. A number of products are widely used in medicine, food and winery industries, and the quality is guaranteed.http://www.wanqingwz.com/data/attachment/portal/202307/31/155427mim4c76ii3hz6htz.jpg
