一般來說對冷拔無（wú）縫鋼管的性能產（chǎn）生影響的元素究竟有（yǒu）哪些？決定冷拔無縫鋼管質（zhì）量的不但有生產工藝，還要其它（tā）重要的因素（sù）對冷拔無縫鋼管性能產生影響。這（zhè）就是冷拔無縫鋼管含量元（yuán）素（sù）多少對鋼管的性能產（chǎn）生重大影響。接下來就讓我們（men）一起來看看。影響的元素：介紹就是能對冷拔無縫鋼（gāng）管性能（néng）產生影響的一些元素，分別有碳、硫、磷、錳，希望以上的內容能（néng）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（de）鋼在（zài）高溫進行壓力加工時，容易脆裂，通常叫作熱脆（cuì）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；能使鋼的（de）可塑性及韌性明顯下（xià）降，特別的在低溫下更為嚴重，這種現象叫作冷脆性（xìng）．在優質鋼中，硫和（hé）磷要嚴格控製．但從（cóng）另（lìng）方（fāng）麵看，在低碳鋼中含有較高的硫（liú）和磷（lín），能使其切削（xuē）易斷（duàn），對改善鋼的可（kě）切削性是有利（lì）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；能提高鋼的強度，能消弱和消除硫的不（bú）良影響，並能提高鋼的淬透性，含錳量很高的高（gāo）合（hé）金鋼（高錳（měng）鋼（gāng））具有良好的耐磨性（xìng）和其它的物（wù）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.
