归类

奥氏体不锈钢

305S19（1.4303）是一种铬镍奥氏体不锈钢，由于镍含量高，加工硬化率低。这种低加工硬化率使得该等级非常适合多级深拉应用，无需工艺退火，其中305S19（1.4303）/ 304L可能会出现开裂问题。为了尽量减少拉制过程中的耳环，在冷轧过程中引入的方向性必须保持在最低限度。订购此合金时应注意拉深质量。它在退火和冷加工条件下是非磁性的，并且具有与 305S19（1.4303）/304L 不锈钢相似的耐腐蚀性。深冲性高于标准 305S19（1.4303）等级。期望这些标准中的规范与本数据表中给出的规范相似但不一定相同是合理的。

305S19 (1.4303) is a chromium nickel austenitic stainless steel with low work hardening rate due to high nickel content. This low work hardening rate makes this grade very suitable for multi-stage deep drawing applications without process annealing, in which 305S19 (1.4303)/304L may have cracking problems. In order to minimize the earrings in the drawing process, the directivity introduced in the cold rolling process must be kept to a minimum. Attention should be paid to the drawing quality when ordering this alloy. It is non-magnetic under annealing and cold working conditions, and has corrosion resistance similar to 305S19 (1.4303)/304L stainless steel. The deep drawability is higher than the standard 305S19 (1.4303) grade. It is reasonable to expect the specifications in these standards to be similar but not necessarily identical to those given in this data sheet.
