304DDQ (deep drawing quality) is a kind of stainless steel material: it refers to the material used for ultra-deep drawing (punching), which is what we call soft material. The main feature of this material is high elongation (≥ 53%), the hardness is low (≤170%), the internal grain grade is between 7.0 and 8.0, and the deep drawing performance is excellent. But the polishing performance is slightly worse. Excellent deep drawing performance. Many companies that produce thermos and pots generally have a higher processing ratio (BLANKING SIZE/product diameter), and their processing ratios are 3.0, 1.96, 2.13 and 1.98, respectively. SUS304DDQ material is mainly used for these products with high processing ratio. Of course, products with a processing ratio of more than 2.0 generally need to go through several passes to complete the stretching. If the extension of the raw material is not reached, the product is prone to cracks and pull-through when processing the deep-drawn product, which affects the qualified rate of the finished product, and of course increases the cost of the manufacturer.
304DDQ is suitable for: household appliances, sink units, serving trays and cutlery, domestic cooking and catering equipment, dairy equipment, welded structures, decorative pipes, exhaust systems, metal framing in the construction industry, deep-drawn components.
