This subtle difference directly triggers a series of key performance changes. In high-temperature environments (such as welding, where temperatures can reach 600-850\u00b0C), carbon in the steel combines with chromium to form chromium carbide. Since chromium is the main element providing stainless steel&#8217;s excellent corrosion resistance, when it is &#8220;fixed&#8221; in carbides, the chromium content around the steel&#8217;s grain boundaries decreases, forming a chromium-depleted zone. This zone acts like a weak point in a defense line, preferentially corroded in corrosive environments, leading to &#8220;intergranular corrosion,&#8221; commonly known as &#8220;weld fading.&#8221; Because of its extremely low carbon content, 316L significantly reduces the opportunity for chromium carbide formation, thus maintaining its overall corrosion resistance well after welding.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-18523\" title=\"\u30b9\u30c6\u30f3\u30ec\u30b9\u92fc\u6eb6\u63a5\" src=\"https:\/\/daxuns.com\/wp-content\/uploads\/2025\/11\/sheet-metal-welding.jpg\" alt=\"\" width=\"691\" height=\"338\" srcset=\"https:\/\/daxuns.com\/wp-content\/uploads\/2025\/11\/sheet-metal-welding.jpg 936w, https:\/\/daxuns.com\/wp-content\/uploads\/2025\/11\/sheet-metal-welding-768x376.jpg 768w\" sizes=\"(max-width: 691px) 100vw, 691px\" \/><\/p>\n<h3><span style=\"color: #3366ff;\">\u6a5f\u68b0\u7684\u7279\u6027<\/span><\/h3>\n<p>\u70ad\u7d20\u542b\u6709\u91cf\u306e\u9055\u3044\u306f\u3001\u6a5f\u68b0\u7684\u7279\u6027\u306e\u9055\u3044\u306b\u3082\u3064\u306a\u304c\u308b\u3002\u70ad\u7d20\u306f\u52b9\u679c\u7684\u306a\u5f37\u5316\u5143\u7d20\u3067\u3042 \u308a\u3001\u70ad\u7d20\u542b\u6709\u91cf\u304c\u9ad8\u3044\u305f\u3081\u3001\u6a19\u6e96\u7684\u306a316\u30b9\u30c6\u30f3\u30ec \u30b9\u92fc\u306f316L\u30b9\u30c6\u30f3\u30ec\u30b9\u92fc\u3088\u308a\u3082\u9ad8\u3044\u5f15\u5f35\u5f37\u3055 \u3068\u964d\u4f0f\u5f37\u3055\u3092\u6301\u3064\u3002\u713c\u920d316\u306e\u5f15\u5f35\u5f37\u3055\u306f\u901a\u5e38\u7d04580 MPa\u3067\u3001316L\u306f\u7d04550 MPa\u3067\u3042\u308b\u3002\u3053\u306e\u3053\u3068\u306f\u3001\u6eb6\u63a5\u304c\u6700\u5c0f\u9650\u307e\u305f\u306f\u5168\u304f\u306a \u3044\u7528\u9014\u3067\u3001\u3088\u308a\u9ad8\u3044\u6a5f\u68b0\u7684\u5fdc\u529b\u304c\u8981\u6c42\u3055\u308c\u308b\u5834 \u5408\u3001316\u306e\u65b9\u304c\u3088\u308a\u5f37\u5ea6\u304c\u9ad8\u3044\u3053\u3068\u3092\u610f\u5473\u3059\u308b\u3002\u3057\u304b\u3057\u3001\u5927\u898f\u6a21\u306a\u6eb6\u63a5\u3092\u4f34\u3046\u30d7\u30ed\u30b8\u30a7\u30af \u30c8\u3067\u306f\u3001316L\u306e\u5229\u70b9\u304c\u660e\u3089\u304b\u306b\u306a\u308b\u3002316L\u306f\u6eb6\u63a5\u304c\u5bb9\u6613\u306a\u3060\u3051\u3067\u306a\u304f\u3001\u8010\u98df\u6027\u3092\u56de\u5fa9\u3059\u308b\u305f\u3081\u306b\u6eb6\u63a5\u5f8c\u306b\u71b1\u51e6\u7406\u3092\u52a0\u3048\u308b\u5fc5\u8981\u304c\u306a\u3044\u305f\u3081\u3001\u88fd\u9020\u5de5\u7a0b\u304c\u5927\u5e45\u306b\u7c21\u7d20\u5316\u3055\u308c\u3001\u30b3\u30b9\u30c8\u3082\u524a\u6e1b\u3067\u304d\u308b\u3002.<\/p>\n<h3><span style=\"color: #3366ff;\">\u30a2\u30d7\u30ea\u30b1\u30fc\u30b7\u30e7\u30f3\u306e\u9055\u3044<\/span><\/h3>\n<p>\u5b9f\u7528\u7684\u306a\u7528\u9014\u3067\u306f\u3001\u6750\u6599\u306e\u9078\u629e\u306f\u3059\u3079\u3066\u7279\u5b9a\u306e\u7528\u9014\u306b\u4f9d\u5b58\u3059\u308b\u3002316\u30b9\u30c6\u30f3\u30ec \u30b9\u92fc\u306f\u3001\u6d77\u6d0b\u74b0\u5883\u7528\u306e\u91d1\u7269\u3001\u5316\u5b66\u51e6\u7406\u88c5\u7f6e\u3001\u9ad8\u5f37\u5ea6 \u3068\u512a\u308c\u305f\u8010\u98df\u6027\u3092\u5fc5\u8981\u3068\u3059\u308b\u4e00\u90e8\u306e\u5efa\u7bc9\u90e8\u54c1\u306e\u88fd\u9020 \u306b\u4e00\u822c\u7684\u306b\u4f7f\u7528\u3055\u308c\u3066\u3044\u308b\u3002\u5bfe\u7167\u7684\u306b\u3001316L\u306f\u88fd\u85ac\u3001\u30d0\u30a4\u30aa\u30c6\u30af\u30ce\u30ed\u30b8\u30fc\u3001\u98df\u54c1\u52a0\u5de5\u7523\u696d\u3067\u597d\u307e\u308c\u307e\u3059\u3002\u3053\u308c\u3089\u306e\u5206\u91ce\u3067\u306f\u3001\u8010\u98df\u6027\u304c\u8981\u6c42\u3055\u308c\u308b\u3060\u3051\u3067\u306a\u304f\u3001\u6eb6\u63a5\u90e8\u306b\u6c5a\u67d3\u3084\u8150\u98df\u306e\u30ea\u30b9\u30af\u304c\u306a\u3044\u3053\u3068\u304c\u4fdd\u8a3c\u3055\u308c\u308b\u304b\u3089\u3067\u3059\u3002.<\/p>","protected":false},"excerpt":{"rendered":"<p>Key Difference: Carbon Content The most crucial difference between 316 and 316L stainless steel lies in their carbon content. 316 stainless steel has a maximum carbon content of 0.08%, while the &#8220;L&#8221; in 316L stands for &#8220;Low Carbon,&#8221; strictly controlling the carbon content below 0.03%.
