Deep Drawing Applications
Stainless steel can be formed into a deep drawn part, such as a kitchen sink, by stretching a flat piece of metal over a form in a die. Pressure is applied to the metal and it moves into the shape of the die. How much pressure is ud to move the material in correlation with lubricants and how much the material flows and stretches are both factors in the outcome of the product. If the mix is not correct, the parts will break or wrinkle. Some deep drawn parts are very deep and/or narrow and cannot be drawn by one hit in the die. They must go through a ries of stretches or a progression of hits to achieve the desired outcome.

The best material to u in deep drawn applications is one that will stretch or form easily while making the part and will not bend after becoming a part. Most drawing is done at room temperature and called a cold-working process. High-nickel alloys in the 300 ries of austenitic stainless steels work very well in this application. The nickel makes the steel ductile and allows it to stretch; at the same time, the metal will work-harden during the cold-working process for a strong part.学生会个人简介
