What is Black Steel?
黑钢或黑碳钢是金属合金或铁和碳以及其他一些金属的混合物。通常,即使我们可以将其融化并将其塑造成所需的形状,纯铁也很软。将碳添加到纯铁中可以提高金属的强度,并且大多数碳钢类型含有1-2%的碳。通常,在钢的生产过程中制造了黑钢,高温可以产生氧化的薄层铁层。这种氧化的铁层是在钢的外表面上产生的。
Typically, iron tends to react easily with oxygen in the air. This reaction creates iron oxide, commonly called rust. This rust formation can cause the failure of some parts of iron. Therefore, the surface of iron is often coated to prevent surface rust formation. An important advantage of black steel is its natural anti-corrosion property, which comes from black iron oxide coating. The oxide layer can act as a barrier to keep oxygen from the iron layer that lies below. This thin oxide layer forms at a high temperature, so the iron does not require any coating.
黑钢通常用于气体或水电管道。这是因为黑钢的生产成本低,并且也可以使用简单的常见方法轻松焊接。通常,一些长距离管道系统使用这种钢可以防止生锈。此外,我们可以在更换或加速腐蚀的气候或地面条件下使用黑色钢。但是,我们有时可能需要其他涂料或预防方法。
什么是低碳钢?
Mild steel is a very common type of carbon steel that has a low amount of carbon by weight. The amount of carbon in this steel is around 0.2%. The other major elements present in it are manganese, silicon, sulfur, and phosphorus. Mild steel is mainly useful in the industry. However, we also use this material in the equipment we use in our day-to-day life.
An important property of mild steel is that it is not brittle. Moreover, it does not readily undergo a tempering process and has considerable strength. In addition, it is a good electrical conductor. Therefore, we can use it in welding. Moreover, it has high malleability because of the low carbon content. Due to its ferromagnetic properties, we can easily magnetize mild steel. Furthermore, this material is suitable for structural purposes. However, compared to low-carbon steel, this material has more carbon and is prone to corrosion.
黑钢和密尔的区别是什么d Steel?
Black steel or black carbon steel is a metal alloy or a mixture of iron and carbon along with small quantities of some other metals. Mild steel is a very common type of carbon steel that has a low amount of carbon by weight. The key difference between black steel and mild steel is that black steel has a dark blue and oily surface, whereas mild steel has a silvery grey and non-oily surface.
The below infographic presents the differences between black steel and mild steel in tabular form for side by side comparison.
Summary – Black Steel vs Mild Steel
Steel is an alloy of iron and carbon along with some other chemical elements. The carbon content in this alloy ranges up to 2% by weight. The key difference between black steel and mild steel is that black steel has a dark blue and oily surface, whereas mild steel has a silvery gray and non-oily surface.
