What Are The Reasons For Tensile Cracking Of Stainless Steel

What are the reasons for the cracking of stainless steel material during stretching?


The practice has proved that the choice of copper-based alloy molds can eliminate scratches and scratches on the surface of stainless steel parts and reduce the damage rate. The other material is high-aluminum copper-based alloy mold material (containing aluminum 13Wt%
16Wt%). 


This material has low miscibility with SUS304 stainless steel, and there is no adhesion between the drawn part and the mold, and the surface of the drawn part is not easy to scratch Scratch, low product polishing cost, has been successfully applied in the field of stainless steel deep drawing.


However, due to the low hardness of this mold (40HRC
45HRC), it is often used to produce products with a relatively small thickness t/D. Generally, after 1500 to 2000 pieces are drawn, it is easy to produce radially drawn edges on the surface of the concave die starting from the round corner.


Silicon nitride ceramics (Si3N4) has become an important engineering material, especially reaction sintered silicon nitride ceramics, which have good high and low-temperature mechanical properties, thermal shock resistance and chemical stability, and can be easily made into complex shapes Components. The high hardness, high wear resistance, and high chemical stability of ceramic materials can be used to draw SUS304 stainless steel with reaction sintered silicon nitride molds instead of metal molds.
