一般來說對冷（lěng）拔無縫鋼管的（de）性能產生影響的元素究竟有哪些？決定冷拔無縫鋼管質量的不但有生產工藝，還要其它重要的因素對冷拔無縫鋼管性能產生影響。這就是冷拔（bá）無縫鋼管含（hán）量元素多少對鋼管的性能產生重大影響。接下來就（jiù）讓我們一起（qǐ）來看看。影響的元素：介紹就是能對冷（lěng）拔無縫（féng）鋼（gāng）管性能產生影響（xiǎng）的一些元素，分別（bié）有碳、硫、磷、錳，希望以上的內（nèi）容（róng）能夠幫助大家。
Generally speaking, what are the elements that affect the performance of cold-drawn seamless steel tubes? The quality of cold-drawn seamless steel tube is determined not only by production technology, but also by other important factors. This is why the content of elements in cold-drawn seamless steel tube has a great influence on the performance of steel tube. Next let's take a look. Influencing Elements: The introduction is to introduce some elements which can affect the performance of cold-drawn seamless steel tubes, including carbon, sulfur, phosphorus and manganese. I hope the above contents can help you. （1）碳；含碳量越高，剛（gāng）的硬度就越高，導致冷拔無縫鋼管的可塑性和韌性就越差。
(1) Carbon; the higher the carbon content, the higher the rigidity, resulting in the worse plasticity and toughness of cold-drawn seamless steel tubes.
（2）硫；是鋼中的有害雜物，含硫較高的鋼在（zài）高（gāo）溫進行壓力加工時，容易脆（cuì）裂，通常叫作（zuò）熱脆性。
(2) Sulphur is a harmful impurity in steel. When the steel with higher sulphur content is processed under pressure at high temperature, it is easy to crack, which is usually called hot brittleness.
(3）磷（lín）；能使鋼的可塑性及韌性明顯下降（jiàng），特別的在低溫下更為嚴重，這種現象叫作冷脆性．在優質鋼中，硫和磷要嚴（yán）格控製．但從另方麵看，在（zài）低碳鋼中含有較高的硫（liú）和磷，能使其切削易斷，對改善鋼的可（kě）切削性是（shì）有利的。
(3) Phosphorus; can make the plasticity and toughness of steel decrease obviously, especially at low temperature. This phenomenon is called cold brittleness. In high-quality steel, sulfur and phosphorus should be strictly controlled. On the other hand, high sulfur and phosphorus content in low carbon steel can make it easy to cut, which is beneficial to improve the machinability of steel.
（4）錳；能提高鋼（gāng）的強度，能消弱和消除硫的不良影響，並能提高鋼的淬透性，含（hán）錳量很（hěn）高的高合金鋼（高錳鋼）具有良好的耐磨性和其它的物理性能。
(4) Manganese; can improve the strength of steel, can weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties.
