不锈钢螺母经过加工或热处理徐州SKF轴承硬化。因此，选择螺母进行热处理，以促*进固体螺母的使用。这里有两个要点，看看哪些螺母适合使用。
Stainless steel nuts are hardened by processing or heat treatment of Xuzhou SKF bearing. Therefore, nuts are selected for heat treatment to promote the use of solid nuts. Here are two main points to see which nuts are suitable for use.
1。热处理不能加强
1. Heat treatment cannot be strengthened
铁素体和奥氏体不锈钢不能通过热处理进行强化。为了提高耐蚀性和塑性，消*除冷加工硬化，应进行固溶处理。对于形状复杂、固溶处理不当的紧固件，可进行应力消*除退火，对于含钛或铌的不锈钢可进行稳定退火。因此，徐州SKF轴承可以获得稳定的耐腐蚀性。
Ferrite and austenitic stainless steel can not be strengthened by heat treatment. In order to improve corrosion resistance and plasticity, solid solution treatment should be carried out to eliminate cold work hardening. For the fasteners with complex shape and improper solution treatment, stress relief and de-annealing can be carried out, and for stainless steel containing titanium or niobium, stable annealing can be carried out. Therefore, Xuzhou SKF bearing can obtain stable corrosion resistance.
2。强化热处理
2. Enhanced heat treatment
马氏体不锈钢要求高*强度和弹性极限。耐腐蚀性低的紧固件应在中温下淬火和回火。具有良好机械性能和耐腐蚀性的紧固件应在高温下淬火和回火。奥氏体-铁素体（双相）不锈钢需要退火以消*除加工应力，降低硬度，提高塑性。只有改进徐州SKF轴承原有结构的紧固件，才能通过高温正火和回火进行预热。
Martensitic stainless steel requires high strength and elastic limit. Fasteners with low corrosion resistance should be quenched and tempered at medium temperature. Fasteners with good mechanical properties and corrosion resistance should be quenched and tempered at high temperatures. Austenitic-ferritic (duplex) stainless steel needs annealing to eliminate working stress, reduce hardness and improve plasticity. only by improving the fastener of the original structure of Xuzhou SKF bearing, can it be preheated by high temperature normalizing and tempering.
特点1：内外圈可自*由拆卸，为轴承的安装拆卸提供了极大的方便。
Feature 1: The inner and outer rings can be disassembled by themselves, which provides great convenience for the installation and disassembly of bearings.
特点二：圆柱滚子轴承对轴承座的加工要求较高。如果轴承座不能满足圆柱滚子轴承的安装要求，就会产生轴承应力不均匀的问题。安装后，必*须仔细检查轴承的外圈线是否有任何偏差。如果发现外环的轴线有偏差，应及时调整徐州SKF轴承。
Characteristic 2: Cylindrical roller bearings have higher requirements for the processing of bearing seat. If the bearing seat can not meet the installation requirements of cylindrical roller bearings, the problem of uneven bearing stress will arise. After installation, it is necessary to carefully check whether there is any deviation in the outer ring line of the bearing. If the axis of the outer ring is found to be deviated, the Xuzhou SKF bearing should be adjusted in time.
特点3：轴向移动可防止安装偏差。圆柱滚子轴承属于NU型轴向运动，在安装过程中不受轴偏移的影响，也可作为自*由端使用。
Feature 3: Axial movement can prevent installation deviation. Cylindrical roller bearings belong to NU type axial motion, which is not affected by shaft offset in the installation process, and can also be used as self* free end.
特点4：低摩擦，能满足高速运转。圆柱滚子轴承在旋转过程中摩擦系数小，非常适合高速运行。
Characteristic 4: Low friction, can meet high-speed operation. Cylindrical roller bearings have small friction coefficient in the process of rotation and are very suitable for high-speed operation.
特性5：属于热稳定产品，适用于电主轴。具有自动温度识别、自感温差变化和开*放式温度补偿功能，从而延长设备的使用寿命，减少轴承内外圈热损伤引起的徐州SKF轴承摩擦。
Characteristic 5: It belongs to thermal stability product and is suitable for motorized spindle. It has the functions of automatic temperature identification, self-inductance temperature variation and open temperature compensation, so as to prolong the service life of the equipment and reduce the friction of Xuzhou SKF bearing caused by thermal damage of the inner and outer rings of the bearing.
