不銹鐵是不銹鋼的一種，其材質(zhì)主要有409、410、430、444等，屬于馬氏體和鐵素體不銹鋼，它們會被吸鐵石吸引。而不銹鋼統(tǒng)一指可以抵抗大氣

或酸等化學介質(zhì)腐蝕的鋼材。但不銹鋼并非不生銹，它只是在不同介質(zhì)中的腐蝕行為不同罷了。常見的不銹鋼材料以金相組織劃分，能夠分為馬氏

體不銹鋼、鐵素體不銹鋼和奧氏體不銹鋼三種類型。不銹鋼不是一直不會生銹的，外部的儲存環(huán)境因素非常重要，在氣候干燥、通風條件好的情況

下不會生銹，如果是連續(xù)的陰雨天氣，或者是空氣中的酸堿度偏高就很容易生銹，潮濕陰暗的環(huán)境中呆的時間久了也很容易生銹。

Unstainless iron is a kind of stainless steel, its material is mainly 409,410,430,444, etc., belongs to martensite and ferritic stainless steel, they will be attracted

by magnet. And stainless steel uniform refers to the steel that can resist the corrosion of chemical media such as atmosphere or acid. But stainless steel is not

without rust, it is just in a different corrosion behavior in different media. Common stainless steel materials are divided into metallographic tissue, which can

be divided into martensite stainless steel, ferrite stainless steel and austenitic stainless steel. Stainless steel is not always rusty, external storage environment

factors are very important, in the dry climate, good ventilation conditions will not rust, if it is continuous rainy weather, or the high acidity in the air is easy to

rust, wet and dark environment for a long time is also easy to rust.
