STANAL 400
固相金属扩散处理,以提高不锈钢部件的抗咬合性。

定义: 400℃ 固 相 金 属 扩 散 处 理 ,STANAL ™ 400 可提高不锈钢部件的抗咬合性,同时不改变更其耐蚀性。

应用实例 :航空电连接器 • 喷气发动机热气旋转接头 • 液压配件 • 核工业使用的不锈钢螺栓 • 核阀零件 • 核燃料箱塞 • 水下门铰链 • 汽轮机叶片定位销 • 软化水环境中核槽门铰链 • 不利环境中(核,海底勘察)运行机器的移动部 件 • 食物混合器 • 绞肉机轴承 • 糕饼制造活塞 • 阀门 • 农业设备保险销 • 射孔器阀 • 分配器活塞 • 传动装置(齿轮) • 高强度钢螺栓 • 马氏体铬不锈钢螺栓 • 连接销等

涂层特性:使用的热循环不可超过 400°C,小心控制扩散现象,制造硬金属合金,形 成 STANAL™400 层。
由于热循环,STANAL ™400 适用于:
– 奥氏体不锈钢,无碳化铬沉淀风险,所以不改变钢的不锈性能。

 
– 结构坚硬的马氏体不锈钢,未改变他们的机械属性。
 
硬度: 根据已处理的钢,硬度为 350-450  HV 
 
涂层厚度: 根据已处理的钢,涂层厚度为 5-10 微米。
 
处理优势:
•提高表面硬度
• 提高耐磨性和抗咬合性
• 具有良好的抗氧化和抗腐蚀特性
• 固体薄膜润滑的优质基底
  
需采取的措施:
•复杂形状的部件应在 400°C 的温度下定型 2 小时,在精加工之前进行缓慢冷却。
• 部件制造时,允许有 12 ± 3 微米的直径膨胀。
• 处理后部可以进行再加工,表面精加工除外,例如抛光,打磨。
 
适用于处理的材料:
 • 所有奥氏体不锈钢:例如:X2CrNi 18.8,X2 CrNiMo 18.10,X3CrNiMo 1812,X6 CrNiTi 17.12 等。
