Diamond internal circular blades is mainly used to cut artificial crystal, single crystal silicon and precious ceramics and other material hard material, which has the advantages of small cutting slit, good cutting flatness and wear resistance.
Therefore, the substrate material of diamond 301 stainless steel knife put forward high requirements, at present, mainly use the thickness of 0.12mm sus301 stainless steel strip as the substrate of diamond stainless steel knife. Cold rolled strips are required to be flat and straight, without edge wave, and without warpage after stamping.
The specific requirements of the user are: Cold rolled strips hardness range: 490 ~ 530HV, preferably controlled at 500 ~ 525HV, elongation of 2.0% ~ 4.0% (transverse and longitudinal extension to be basically the same). Strip tensile strength in 1 650 ~ 1800MPa. usually we call this 301 stainless steel strip for 301 stainless steel 1/2 hard.
The key to the production of this 301 stainless steel strip is to control the Cold rolled strips plate shape and performance.
In this paper, we have optimized the best production process through repeated experiments, especially the cold rolling process, drawing and straightening process and stress relief annealing process, so that we can produce 301 stainless steel strips with good shape and excellent performance for diamond insert substrate stably.

The performance of diamond insert matrix directly affects the service life of the insert, and the performance of Cold rolled strips determines the performance of diamond insert matrix, so the design of cold rolling process is especially critical. Through long-term cold rolled production and experiments, tensile tests and hardness measurements were conducted on products with different deformations, so that the work hardening curve of SUS301 stainless steel strip was drawn, and the cold rolling process of 301 stainless steel strip for diamond insert substrate was determined.
When the deformation rate is between 48% and 54%, the hardness of Cold rolled strips is between 480 and 520 HV, the tensile strength is between 1640 and 1760 MPa, the yield strength is between 1360 and 1480 MPa, and the elongation is between 5% and 8%. Considering that the strip mechanical properties will be increased in the post-step when tensile bending straightening and stress relief annealing are also required, the deflection rate of the final rolling process is controlled at 52% ± 2%.
Through continuous experiments, this paper adopts the production process of three rolling and two annealing, which can meet the performance requirements of the product and is more economical. In the 12-roller precision cold rolling mill, the 1.2mm blank is cold rolled to 0.12mm, and the process parameters such as rolling force, rolling tension, amount of string rolls, rolling speed, rolling temperature and deformation rate of the pass are controlled in the rolling process, so as to control the performance and board shape of Cold rolled strips.
If the plate shape of the cold rolled strips can not reach very flat, then in the process of processing into diamond inner circle blade, in the use of the process due to uneven force on the blade, easy to lead to be cut by the uneven size of the product, and even the blade is torn. Therefore, it is necessary to straighten the cold rolled strips by stretching and bending, so as to ensure the flat shape of Cold rolled strips.
According to the experience accumulated from many experiments, the elongation in this experiment is set between 0.8% and 1.5%, depending on the shape of the cold rolled strips, and the tension is set between 25000 and 40000N, so that the strip shape is flatter after drawing and straightening, and the I value shown on the plate shape measuring instrument is basically between 0 and 1.
The following figure is an actual example of this experiment, in which the process parameters are continuously adjusted, and the final set of the finished drawing and straightening process parameters are: elongation set to 1.0%, the actual display value of 1.06%. Tension is set to 28000N, the actual value is 28380N, the plate shape measuring instrument shows the I value basically in the middle of 0 ~ 1, stretching bending straightening treatment after the strip plate shape is very flat.
Stress relief annealing, also known as tension annealing, is a continuous heat treatment under a certain tension, which is a heat treatment method with temperature, time and tension. It can effectively remove the internal stress of the strip due to mechanical processing, deformation processing, etc., and reduce the deformation and cracking and other adverse effects during the subsequent processing.
Based on the effect of stress relief annealing on the shape of Cold rolled strips, two factors (annealing temperature and annealing speed), which have a significant effect on the strip properties, are considered in the design of the experimental program. The cold-rolled strip to 0.12 mm, first cut the edge, then after stretching and bending straightening treatment, and then separately take 2 meters of each strip after pulling and straightening, after stress relief annealing treatment.
Through the stress relief annealing experiment, when the annealing temperature of 300 ℃, annealing speed of 12.5m / min, the best mechanical properties of the annealed strip, its hardness of 512.4 HV, tensile strength of 1696.7 MPa, yield strength of 1531.7 MPa, elongation of 3.3%. After stress relief annealing 301 stainless steel strip performance is the final performance of the product, according to product performance requirements, combined with the results of stress relief annealing experiments to determine the best stress relief annealing process parameters: annealing temperature of 300 ℃, annealing speed of 12.5m / min, the unit tension is usually set to 20MPa (depending on the strip plate shape after drawing and straightening) . The whole coil strip according to: annealing temperature of 300 ℃, annealing speed of 12.5m / min, unit tension of 20MPa, after stress relief annealing treatment.
301 stainless steel coil properties are: the average hardness of the strip is 524.2HV, the average transverse tensile strength of 1690MPa, the average longitudinal tensile strength of 1695MPa, the average transverse yield strength of 1548MPa, the average longitudinal yield strength of 1510MPa, the average transverse elongation of 2.3%, the average longitudinal elongation of 3.5%. The average elongation is 2.3%, longitudinal elongation is 3.9%, and its performance meets the customer’s requirements.
Using the above cold rolling process, drawing and straightening process and stress relief annealing process, the production of 0.12mm thick 301 stainless steel strip plate shape flat, the strip flat on the platform for visual inspection, 301 stainless steel coil and platform completely fit without gaps. When slicing 252mm×252mm, the strip is flat and without warpage. When turning into diamond inner circle blade basic also very flat, will be flat on the platform for visual inspection, the strip still with the platform completely fit without gap, later in the production of diamond inner circle blade process, also not easy to deformation, not easy to blow up, blade life can reach about 1500 times, improve the service life of the blade, reduce production costs.
