>Processing method
Mechanical processing
Cutting tools
Has higher hardness and cutting resistance than other steel types. Larger drills Hole processing
When drilling, the larger the diameter of the drilled hole, the smaller the cutting speed. If the spiral groove is shorter than the standard minimum length, the risk of tool breakage will be reduced.
Milling machine processing
The feed amount is regarded as a standard. If the feed amount is too large, the tool life will be reduced.
Planer processing
It is recommended to use a cemented carbide planer. For the cemented carbide planer, the back bevel angle of the tool should be about ℃ and the front clearance angle should be below ℃. This way, better results can be obtained. Precipitation hardening type planer Hard steel, with a hardness of about 100 Å, can be used directly without further heat treatment.
Solid solution treatment
The purpose is to uniformly dissolve the alloy components in austenite. Because it is not quenched and hardened, it does not require a fast cooling rate, so there will be no large residual internal stress.
Precipitation hardening treatment
The temperature is raised and maintained for a considerable time, and intermetallic compounds such as nickel, aluminum, and copper are precipitated to harden the material. Since it does not need to be hardened by quenching, there is no problem with the quality of ordinary steel materials. Even thicker steel materials can obtain a very uniform cross-sectional hardness distribution.
Welding performance
Neither the welding joint nor the heat-affected zone will harden, and the hardness is slightly lower than that of the base material (it has been precipitation hardened, but the hardness can be restored by applying precipitation hardening treatment at ℃* hours after welding. < br/> Grinding processability
Compared with other steel types, it is easier to achieve mirror surface requirements because of the following two points
Because it is a low-carbon precipitation hardened steel, it has a fine and uniform microstructure. During grinding and polishing Before grinding, the surface must first achieve the required flatness, straightness, and correct shape and size.
Use a complete series of abrasive materials, from coarse to fine, and use them in accordance with regulations. Grinding cannot be skipped.
The direction of each grinding and polishing should be perpendicular to the direction of the marks left by the previous one.
The abrasive particles used should be uniform.
Use grinding or polishing tools that are softer than the workpiece.
If When using a grinding stone, it should be softer and first made into a shape that matches the shape of the surface to be ground.
If the work is suspended and the semi-finished workpiece must be left for a period of time, its surface must be clean and stored in a dry place Place
When polishing
Polishing should be fast and light, and surface unevenness must be minimized before polishing.
