316L不锈钢属于低碳不锈钢，具有优良的抗腐蚀性能，在一定条件下，可代替稳定型不锈钢(321、347)用于抗介质的腐蚀；超低碳不锈钢高温机械性能较低，一般仅用于温度低于525℃的条件下；稳定型奥氏体不锈钢既具有较好的抗腐蚀性能，又有较高的高温机械性能，但321中的Ti在焊接过程中易被氧化而失掉，从而降低了其抗腐蚀性能，其价格较高，这类材料一般用在较重要的场合，304、316具有一般的抗腐蚀性能，价格便宜，因此被广泛应用。

The 316L stainless steel belongs to the low-carbon stainless steel, Excellent corrosion resistance properties, Under certain conditions, Instead of stable stainless steel (321,347) for medium corrosion resistance; Ultra low carbon stainless steel high temperature mechanical performance, It is generally used only for temperatures of less than 525℃; Stable austenitic stainless steel has good corrosion resistance, And has a higher high-temperature mechanical performance, However, the Ti in 321 is easily oxidized and lost during welding, Thus, its corrosion resistance is reduced, Its price is higher, Such materials are generally used on more important occasions, 304,316 With a general corrosion resistance performance, cheapness, It is therefore widely used.

316L不锈钢管是一种中空的长条圆形钢材，主要广泛用于石油、化工、医疗、食品、轻工、机械仪表等工业输送管道以及机械结构部件等。另外，在折弯、抗扭强度相同时，重量较轻，所以也广泛用于制造机械零件和工程结构。也常用作生产各种常规武器、枪管、炮弹等。

316L stainless steel pipe is a hollow long strip of circular steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transport pipelines as well as mechanical structural components.In addition, when the bending and torsion strength is the same, the weight is light, so it is widely used to manufacturing mechanical parts and engineering structures.Also commonly used for the production of various conventional weapons, guns, shells, etc.

316L不锈钢管所有金属的表面都会随着空气中的氧气而变化，在金属表面形成一层氧化膜。不同的是，在普通碳钢表面形成的氧化铁会继续氧化，导致腐蚀不断膨胀，最终形成孔洞。316L不锈钢管材的表层也会与氧气产生反应，但因为其铬含量较高，再加上316L不锈钢管材的耐腐蚀性的关键在于铬含量。当316L不锈钢的铬含量的占比超过10.5%时，316L不锈钢的耐腐蚀性能会得到大大地提升。当316L不锈钢的铬含量的占比超过17%，316L不锈钢的耐腐蚀性能会变得很强。

The surface of all the metals of the 316L stainless steel tube varies with the oxygen in the air, forming an oxide film on the metal surface.The difference is that iron oxide formed on ordinary carbon steel surfaces continues to oxidi, causing expanding corrosion and eventually forming holes.The surface layer of 316L stainless steel pipes will also react with oxygen, but because of their high chromium content, the key to the corrosion resistance of 316L stainless steel pipes lies in the chromium content.When the chromium content of 316L stainless steel exceeds 10.5%, the corrosion resistance of 316L stainless steel is greatly improved.When the 316L stainless steel accounts for more than 17% of the chromium content, the corrosion resistance of the 316L stainless steel becomes very strong.
