| 中文摘要 | AISI 630不�袗�屬麻田散鐵系析出硬化型不�袗�,該鋼種之鍛造性困難,熱加工溫度範圍狹窄,當溫度降至980℃以下時的熱塑性不佳,在高溫時又會因晶粒粗大及δ-ferrite之析出而產生熱加工斷裂。 榮剛重工經深入的研究,已可利用δ-ferrite之控制技巧、擬恆溫鍛造及軋延的控制,目前已可產製φ12∼165 mm之AISI 630棒材,其品質已達ASTM A564及AMS 5643等國際規範之標準,除此之外榮剛重工所產製AISI 630之棒材,若經兩次H1150之熱處理後,亦能符合API 6A-60 ℃之低溫衝擊規格標準。 本文係就AISI 630不�袗�之材料特性、製程及管制要點,作一綜合性之介紹說明。 |
| 英文摘要 | AISI 630 is martensitic precipitation hardening stainless steel that is difficult in hot forming because the range of forming temperature is very narrow. When the forging temperature falls below 980℃, the formability is very poor. At higher temperatures the grain will grow and δ-ferrite will form, which will lead to failure in forging process. GHIC has developed a δ-ferrite control technique, induding quasi-isothermal forging and controlled rolling to produce precipitation hardening stainless steel type AISI 630 within size range from φ 12 mm to φ 165 mm. The properties of products conform to the commercial, industrial and aerospace specifications, such as ASTM A564, AMS 5643, etc.. The impact value under HH1150 condition at-60 ℃ is also satisfactory to the specification of API 6A under temperature classification KPSL3. The material properties and the key process parameters during production will be discussed in this paper. |
