详细说明
无缝管详细说明: 武钢
无缝管规格:6-1240×1-200mm
无缝管制造工艺:热轧、冷拔、热扩
不锈钢无缝钢管是一种具有中空截面、周边没有接缝的长条钢材。不锈钢无缝管
不锈钢无缝管的特点:
其一、该产品的壁厚越厚，它就越具有经济性和实用性，壁厚越薄，它的加工成本就会大幅度的上升；其次、该产品的工艺决定它的局限性能，一般无缝钢管精度低:壁厚不均匀、管内外表光亮度低、定尺成本高，且内外表还有麻点、黑点不易去除；其三、它的检测及整形必须离线处理。因此它在高压、高强度、机械结构用材方面体现了它的优越性。
不锈钢管的种类:
接轧制方法分热轧、热挤压和冷拔(轧)不锈钢管。
按不锈钢金相组织不同分半铁素体半马氏体系不锈钢管、马氏体不锈钢管、奥氏体系不锈钢管、奥氏体-铁素铁系不锈钢管等。
