1) Stainless steels are ‘stainless’because their chromium content gives them remarkable resistance to corrosion. Ferritic grades, containing only chromium and possibly other elements (Mo, Ti, Nb, etc.), are no exception.
不锈钢的“不锈”，是由于所含的铬使其具有了显著的耐蚀性。铁素体不锈钢也不例外，有的钢种仅含铬，有的钢种还含有其他元素（如Mo、Ti、Nb 等）。
2)Well-known standard ferritic grades 409, 410 and 430 are readily available all over the world. Very successfully used in important applications, such as washing-machine drums and exhaust systems, they actually have much broader application potential, in numerous fields.
大家熟知的标准铁素体不锈钢409、410 和430 在全世界都可买到。它们在洗衣机滚桶、排汽系统等许多重要应用领域中的使用都非常成功。实际上，铁素体不锈钢在无数领域中都有更加广泛的应用潜力。
3) We accordingly design our products with the necessary manufacturing considerations in mind and occasionally select a coated grade and even a fingerprint-protected coated grade, if need be, to ensure long service life. We may, on occasion, use a higher-alloyed ferritic grade. The important thing is to benefit from the economic advantages of using ferritics.
我们按照必须的制造要求来设计我们的产品，有时会选择有涂层的铁素体不锈钢，甚至在需要时选择有防指纹涂层的不锈钢，以确保较长的使用寿命。我们有时也会采用高合金的铁素体不锈钢。重要的是，能够从铁素体不锈钢的使用中获得经济效益。
4) In factories where 304 is predominantly used, changing to ferritic grades means adjusting the manufacturing process and dies. This is costly. Our experience, however, shows that total production costs can be lowered with ferritics.
对那些主要采用304 的厂家来说，转而采用铁素体不锈钢意味着必须对制造工艺和冲模进行调整。这需要一定投资。但从我们的经验来看，采用铁素体不锈钢能够降低整个生产成本。
