                                                                                            發布時間:2019-09-18人氣:104

                                                                                              無縫鋼管在我們日常使用中隨處可見,廣泛應用于多個領域,下面簡單介紹一下無縫鋼管的三大特性。

                                                                                              1、耐腐蝕性

                                                                                              大多數不銹鋼產品需要良好的耐腐蝕性。無縫鋼管類似于I類和II類餐具,廚房用具,熱水器,飲水機等。一些外國商人也對產品進行耐腐蝕性測試:使用NACL水溶液溫熱至沸騰,一段時間后解決方案是排干,洗滌和干燥,確定重量損失以確定腐蝕程度。

                                                                                              2、焊接加工性

                                                                                              焊接性能的要求因產品而異。一種餐具通常不需要焊接性能,甚至包括一些鍋企業。但是,大多數產品要求原材料具有良好的焊接性能,如二類餐具,保溫杯,鋼管,熱水器,飲水機等。

                                                                                              3、拋光性

                                                                                              目前,不銹鋼產品在生產過程中一般都是拋光的,只有少數產品如熱水器,飲水機襯里等不需要拋光。因此,這需要原料的良好拋光性能。影響拋光性能的主要因素如下:

                                                                                              1.原料表面缺陷。如劃痕,麻點,浸泡等。

                                                                                              2.無縫鋼管原料問題。硬度太低,拋光時不易拋光(BQ不好),硬度太低,深拉時表面容易出現橘皮現象,影響BQ性能。高硬度的BQ相對較好。

                                                                                              3.深拉后,變形較大的區域表面也會出現小黑點和RI高仿DGING,這會影響BQ屬性。
