(2) Surface quality: stainless steel sheet is a very high price material stainless steel cord, customers of its surface quality requirements are very high. But stainless steel sheet in the production process will inevitably be a variety of defects, such as scratches, pits, creases, pollution, etc., so that its surface quality, such as scratches, creases and other advanced materials, whether these defects are still low is not allowed, and this defect in pitting spoon, spoon, fork, the production is never allowed because it is difficult to discard polishing. We according to the degree and frequency of surface defects of various PR stainless steel cord where the good, to determine its quality and grade table, thereby to determine the product grade. (1) Material: ①DDQ (deep drawing quality) material: refers to a material for deep drawing Guancheng (punch) the use of stainless steel cord phone company, that is, we called the soft material, the main characteristics of this material higher elongation (≥53%), low hardness (≤170%), internal grain grading between 7.0 to 8.0 Guancheng stainless steel cord Which promotions, excellent deep drawing properties. Many production thermos pot class enterprises, processing their products generally are higher than (BLANKING SIZE / products in diameter), their processing than 3.0,1.96,2.13,1.98 respectively. SUS304 DDQ timber is mainly used for processing these requests higher than that of the product, of course, working ratio of more than 2.0 products are generally subject to few the stretch to complete. If the extension of terms of raw materials can not reach it, in the processing of deep-drawing products product easy to crack, pull through the phenomenon, affecting the rate of qualified products, of course, will increase the cost of manufacturers; ② general material: mainly used in addition to DDQ material applications outside the characteristics of this material are relatively low elongation (≥45%), while relatively high hardness (≤180), internal grain grade at 8.0 to 9.0, compared with DDQ timber, it Drawability relatively marginal, it is mainly used in the products can be obtained without thrust, like a kind of tableware spoon, spoon, fork, electrical appliances, steel pipe uses. But it is compared with DDQ material has the advantage that BQ relatively good, mainly due to a slightly higher because of its hardness. Guancheng stainless steel cord Which is good service, Shengyuan stainless steel, stainless steel cord Ltd Dongguan Shengyuan by stainless steel. Dongguan Shengyuan Stainless Steel Co.
