What Is Non Alloy Steel?什麽是非合金鋼？

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.

鋼通常被稱為碳鋼，因為它是碳原子和鐵原子的混合物。添加的元素為鋼提供了延展性和強度。在冶煉過程中，其他元素，如鋁，被添加到鋼中，使其成為合金鋼。非合金鋼在冶煉過程中沒有添加任何元素。

Manufacturing製造業

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.

鋼的製造是通過將礦石放入爐中冶煉礦石來完成的。冶煉過程會去除鐵礦石中的任何雜質。一旦進行了第一次冶煉過程，鋼的碳含量仍然太高，無法成為非合金鋼。冶煉過程一次又一次地進行，直到礦石中的碳含量降至總含量的1.5%以下。

Smelting冶煉

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.

冶煉過程熔化鐵礦石。通過熔化礦石，可以完成元素和雜質的提取。製造商隻希望從礦石中提取鐵和少量碳來製造非合金鋼。在冶煉過程中，鈷、銅和鋁等元素被添加到礦石中，使鋼成為合金鋼。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.

非合金鋼在冶煉過程中沒有其他元素添加到鐵和碳中。

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.

非合金鋼必須在一定溫度下回火，因為它不使用其他元素使其靈活耐用。在一定溫度下回火非合金鋼會使鋼在焊接時更容易開裂。

Applications應用

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.

非合金鋼可用於不同的應用。用於加固混凝土的鋼筋是一種非合金鋼。鍛鐵是另一種非合金鋼，因為它在鐵礦石中幾乎不含碳。鍛鐵很軟，很容易加工成不同的形狀，但強度很小。非合金鋼通常用於製作裝飾性金屬門和圍欄。
