奧氏體不銹鋼

305S19（1.4303）是一種鉻鎳奧氏體不銹鋼，由于鎳含量高，加工硬化率低。這種低加工硬化率使得該等級(jí)非常適合多級(jí)深拉應(yīng)用，無(wú)需工藝退火，其中305S19（1.4303）/ 304L可能會(huì)出現(xiàn)開(kāi)裂問(wèn)題。為了盡量減少拉制過(guò)程中的耳環(huán)，在冷軋過(guò)程中引入的方向性必須保持在最低限度。訂購(gòu)此合金時(shí)應(yīng)注意拉深質(zhì)量。它在退火和冷加工條件下是非磁性的，并且具有與 305S19（1.4303）/304L 不銹鋼相似的耐腐蝕性。深沖性高于標(biāo)準(zhǔn) 305S19（1.4303）等級(jí)。期望這些標(biāo)準(zhǔn)中的規(guī)范與本數(shù)據(jù)表中給出的規(guī)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.
