15-5PH不鏽鋼的性能和化學(xué)成分介紹

15-5PH不鏽鋼屬於馬氏體沉澱與時(shí)效硬化不鏽鋼,具有高強(qiáng)度和硬度以及優(yōu)異的耐腐蝕性?;瘜W(xué)成分分析是平衡的,可以產(chǎn)生*小的δ鐵素體,所以還具有優(yōu)異的橫向韌性和延展性,以及良好的鍛造性。

15-5PH的製造特性和其他沉澱硬化不鏽鋼材質(zhì)相似, 它們可以通過單步老化硬化,低溫處理。

該材質(zhì)不鏽鋼可用於閥部件、配件和緊固件、鍛造軸和齒輪、發(fā)動(dòng)機(jī)部件、化學(xué)工藝設(shè)備、造紙?jiān)O(shè)備以及飛機(jī)和核反應(yīng)堆的部件。

15-5PH不鏽鋼

在鍛造時(shí),該不鏽鋼材質(zhì)應(yīng)均勻加熱至1180 /1205℃,並鍛煉1小時(shí)。為了獲得*佳的晶粒尺寸和機(jī)械性能,鍛造材料應(yīng)在進(jìn)一步加工之前將其風(fēng)冷至32℃以下。硬化前必須對(duì)該不鏽鋼材料進(jìn)行固溶處理。

熱處理
15-5PH
一般在溶液處理?xiàng)l件中提供,可以通過將溶液處理的材料加熱至480℃至620℃的溫度並硬化1-4小時(shí),具體取決於溫度,然後空氣冷卻。

1040+/-14℃的溫度下加熱1-2小時(shí),冷卻至32℃以下,從而完全轉(zhuǎn)化為馬氏體。但此時(shí)材料由於韌性較差,衝擊強(qiáng)度差,應(yīng)力腐蝕開裂敏感,材料不能用於溶液處理?xiàng)l件。

15-5PH不鏽鋼切削加工性較好,在溶液處理和各種老化硬化條件下都容易加工。當(dāng)以與302不鏽鋼和304不鏽鋼相似的方式對(duì)材料機(jī)械進(jìn)行固溶處理時(shí),隨著硬化溫度的升高,加工性提高。*佳切削性從條件1150M獲得。

該材料的焊接性也非常不錯(cuò),可以通過屏蔽熔接和電阻焊接工藝獲得令人滿意地焊接效果。因?yàn)樘嘉盏目赡苄?,不推薦采用氧乙炔焊接。焊接接頭應(yīng)設(shè)計(jì)成*小化應(yīng)力。在溶液處理?xiàng)l件下的焊接通常是令人滿意的,但是如果預(yù)期焊接應(yīng)力很高,*好在H1150焊接過時(shí)的狀態(tài),焊接前通常不需要進(jìn)行預(yù)熱。
