What Is Non Alloy Steel?什么是非合金钢？

Steel is common called carbon steel because of the mixture of carbon atoms with iron atoms. The added elements provide the steel with ductility and strength. During the smelting process, other elements, such as aluminum is added to the steel making it an alloy steel. Non-alloy steel has no elements added to the steel as it is smelted.

钢通常被称为碳钢，因为它是碳原子和铁原子的混合物。添加的元素为钢提供了延展性和强度。在冶炼过程中，其他元素，如铝，被添加到钢中，使其成为合金钢。非合金钢在冶炼过程中没有添加任何元素。

Manufacturing制造业

The manufacturing of steel is done by placing ore in a furnace a smelting the ore. The smelting process removes any impurities in the iron ore. Once the first smelting process is performed, the steel still has too much carbon content to become non-alloy steel. The smelting process is performed again and again until the carbon content in the ore falls below 1.5 percent of the total content.

钢的制造是通过将矿石放入炉中冶炼矿石来完成的。冶炼过程会去除铁矿石中的任何杂质。一旦进行了第一次冶炼过程，钢的碳含量仍然太高，无法成为非合金钢。冶炼过程一次又一次地进行，直到矿石中的碳含量降至总含量的1.5%以下。

Smelting冶炼

The smelting process melts the iron ore. By melting the ore, the extraction of elements and impurities can be accomplished. The manufacturer only wants the iron and a small amount of carbon from the ore to make non-alloy steel.

冶炼过程熔化铁矿石。通过熔化矿石，可以完成元素和杂质的提取。制造商只希望从矿石中提取铁和少量碳来制造非合金钢。在冶炼过程中，钴、铜和铝等元素被添加到矿石中，使钢成为合金钢。During the smelting process, elements get added to the ore such as cobalt, copper and aluminum, which makes the steel an alloy steel. Non-alloy steel has no other elements added to the iron and carbon during the smelting process.

非合金钢在冶炼过程中没有其他元素添加到铁和碳中。

Tempering回火

The non-alloy steel must be tempered at a certain temperature because it does not use other elements to make it flexible and durable. Tempering non-alloy steel at a certain temperature make the steel more sensitive to cracking when being welded.

非合金钢必须在一定温度下回火，因为它不使用其他元素使其灵活耐用。在一定温度下回火非合金钢会使钢在焊接时更容易开裂。

Applications应用

Non-alloy steel can be used for different applications. Steel bars used to strengthen concrete is a non-alloy steel. Wrought iron is another non-alloy steel because it has little to no carbon within the iron ore. The wrought iron is soft and easily workable into different shapes but has very little strength. Non-alloy steel is often used to make decorative metal gates and fences.

非合金钢可用于不同的应用。用于加固混凝土的钢筋是一种非合金钢。锻铁是另一种非合金钢，因为它在铁矿石中几乎不含碳。锻铁很软，很容易加工成不同的形状，但强度很小。非合金钢通常用于制作装饰性金属门和围栏。
