Mini Cylinder Pipe
气缸管是一种通过冷拔或热轧处理后的一种高精密的钢管材料。由于精密钢管内外壁无氧化层、承受高压无泄漏、高精度、高光洁度、冷弯不变形、扩口、压扁无裂缝等有点所以主要用来生产气动或液压元件的产品，使用不锈钢材质来做气缸管具有产品设计轻小和使用寿命长的特点。因为不锈钢材质具有高强度和耐腐蚀性，相对铝、铁等材质而言，由于强度高，无磁性，因此可以设计比铝铁材质轻薄，可以降低产品的大小和重量，用于迷你气缸比较多.是轻便自动化设备的首选。不锈钢气缸管内外粗糙度可达Ra0.2-0.4μm,内外径公差最高带可达0.03mm;规格从内径Φ3--Φ100mm,壁厚0.5-8mm。

MANUFACTURING PROCESS & SPECIFICATIONS
热穿孔 用于制造热成品管材.
冷轧轧制是用于生产无缝，冷加工精整的一种广泛使用的步骤中，高合金，不锈钢和镍基合金管材，与能够达到较低的外部的过程直径和比热穿孔空心的公差更严密.
冷拔用于获得较小的公差范围(外径和壁厚).
光亮&固溶退火是在冷加工后释放压力.
大久金属科技生产中使用的原材料来自最可靠的钢厂。
奥氏体不锈钢
这种类型的等级涵盖了不锈钢等级的大部分。定义该等级的是超过15％的铬百分比，它们可抵抗由化学影响引起的不同类型的腐蚀。奥氏体不锈钢牌号的一种特定类型是耐热不锈钢牌号，当暴露于高温下时，它们可以保持其机械性能。
双工-超双工
与标准奥氏体等级相比，奥氏体-铁素体不锈钢（双相钢）的特点是镍的含量相对较低。它们的主要特征是机械性能，特别是其高应力腐蚀开裂性。它们特别适合于海上应用和化学工业。
