『壹』 澳洲標准AS1163 C350 鋼材對應的中國標准
相當於國標中的Q345,即原標准中的16Mn
『貳』 澳洲標准C300鋼材相當於中國哪個牌號
馬氏體時效鋼是以無碳或超低碳Fe-Ni馬氏體為基體,經過時效處理使金屬間化合物沉澱硬化的一種超高強度鋼。這類鋼的強度並不來自於碳,而來自於金屬間化合物的沉澱。
鋼種來源
美國18Ni鋼是馬氏體時效鋼的代表鋼種,按抗拉強度的數值(單位KSI,1KSI=6.89476MPa)分為四個等級:
性能特點
上海秉爭實業有限公司18Ni鋼固溶以後形成超低碳馬氏體,硬度為28~30HRC,時效處理以後,由於各種類型的金屬間化合物的脫溶析出得到時效硬化,硬度可以上升到50HRC。18Ni鋼突出的特點是,在超高強度、高硬度的條件下,仍具有良好的韌性和高的斷裂韌度。同時,這類鋼無冷作硬化,時效熱處理變形小,焊接性能良好,表面還可以滲氮處理等。
上海秉爭實業有限公司18Ni馬氏體時效鋼具有較高的強度和硬度(超高抗拉強度,表面硬度50~54HRC),兼具良好的韌性和塑性,是製造航空航天和國防工業裝備的一種關鍵材料,在航空、航天、精密模具等工業領域獲得廣泛應用,目前在國內外廣泛用作製造火箭發動機殼體、導彈殼體、鈾同位素離心分離機高速轉筒等高精密承重零件的材料。
『叄』 保溫瓶什麼品牌好求推薦
膳魔師、哈爾斯、虎牌保溫瓶好。推薦膳魔師。
膳魔師,德國品牌,誕生於1904年。產地:馬來西亞、中國,日本原裝本土版。
膳魔師的保溫杯,有兩個產地:中國、馬來西亞。保溫效果也很好,和象印、虎牌沒有本質區別,但可能是包裝不夠精緻,或者是因為膳魔師打折次數太多了,給人的感覺檔次比不上象印和虎牌。
順便一提的是,日版的膳魔師,產地會有獨特的THERMOS.K.K,而國內和港版的都沒有,這個可以甄別是否是日本本土版的依據。
『肆』 澳大利亞牌號AS1163或AS350的鋼材對應的國內牌號是什麼
AS1163 - C350L0
Grade C350L0 has a higher yield strength than grade C250L0, which means that lighter, more economical sections can be used to replace heavier sections in many applications.
Australian Tube Mills Grade C350L0 steels are fully compliant with AS 1163 and can be readily processed to Australian/New Zealand Standards and/or instry practice for:
General, mechanical, piping and structural fabrication
Rolling/bending member lengths
Welding
Galvanizing
Surface preparation for top coats
End processing (screwed, swaged)
– for CHS.
Due to the refined chemistry and higher level of working ring the coil and tube manufacturing process, C350L0 steel grade is available in the following ATM tubular procts:
CHS
RHS
UniRail
StockRail
Other sections based on enquiry.
ATM Grade C350L0 steel procts are rated to meet AS 1163 (Table 4) Charpy V-Notch impact test requirements at the test temperature of 0°C (i.e. L0). This property is important for use in lower temperatures and also critical for non-brittle behaviour of tubular procts subject to dynamic loads – particularly for thicker sections and
welded connections.
The mid-to-higher strength properties, ctility and ability to satisfy the above performance criteria of Grade C350L0 is achieved by the following material characteristics as required by AS 1163.
Specifications and Standards
Minimum Yield Strength: 350 MPa (a measure of how strong the tube is – see Table 3).
Standard designation: AS 1163 – C350L0 see definition at the end of this Guide).
Steelmaking process: Fine-grain continuously-cast practice.
Proct manufacture: Cold-forming and high frequency Electric Resistance Welding (ERW) of steel strip. The cold-forming process enhances the strength, hardness and surface finish of the manufactured proct.
Chemical composition: See Table 4 which applies to steelmake cast analysis and finished proct analysis.
Carbon Equivalence (CE): 0.39 – see Table 4 for details.
Welding Code Steel Type: Type 5 (from Table 4.6.1(B) of AS/NZS 1554.1 and Table 4.5.1(B) in AS/NZS 1554.5).
Mechanical properties: See Table 3 for tensile test and below for impact test requirements. For cold-flattening tests, AS 1163 requires deformation to 75% of initial tube depth.
Impact Properties: Satisfies Clauses 15.2 and 16.2 of AS 1163 for Charpy V-Notch impact tests at the test temperature of 0oC (i.e. L0).
