c350是什么钢材

『壹』 澳洲标准AS1163 C350 钢材对应的中国标准

相当于国标中的Q345，即原标准中的16Mn

『贰』 澳洲标准C300钢材相当于中国哪个牌号

马氏体时效钢是以无碳或超低碳Fe-Ni马氏体为基体，经过时效处理使金属间化合物沉淀硬化的一种超高强度钢。这类钢的强度并不来自于碳，而来自于金属间化合物的沉淀。

钢种来源

美国18Ni钢是马氏体时效钢的代表钢种，按抗拉强度的数值(单位KSI，1KSI=6.89476MPa)分为四个等级：

性能特点

上海秉争实业有限公司18Ni钢固溶以后形成超低碳马氏体，硬度为28~30HRC，时效处理以后，由于各种类型的金属间化合物的脱溶析出得到时效硬化，硬度可以上升到50HRC。18Ni钢突出的特点是，在超高强度、高硬度的条件下，仍具有良好的韧性和高的断裂韧度。同时，这类钢无冷作硬化，时效热处理变形小，焊接性能良好，表面还可以渗氮处理等。

上海秉争实业有限公司18Ni马氏体时效钢具有较高的强度和硬度（超高抗拉强度，表面硬度50~54HRC），兼具良好的韧性和塑性，是制造航空航天和国防工业装备的一种关键材料，在航空、航天、精密模具等工业领域获得广泛应用，目前在国内外广泛用作制造火箭发动机壳体、导弹壳体、铀同位素离心分离机高速转筒等高精密承重零件的材料。

『叁』 保温瓶什么品牌好求推荐

膳魔师、哈尔斯、虎牌保温瓶好。推荐膳魔师。

膳魔师，德国品牌，诞生于1904年。产地：马来西亚、中国，日本原装本土版。

膳魔师的保温杯，有两个产地：中国、马来西亚。保温效果也很好，和象印、虎牌没有本质区别，但可能是包装不够精致，或者是因为膳魔师打折次数太多了，给人的感觉档次比不上象印和虎牌。

顺便一提的是，日版的膳魔师，产地会有独特的THERMOS.K.K，而国内和港版的都没有，这个可以甄别是否是日本本土版的依据。

『肆』 澳大利亚牌号AS1163或AS350的钢材对应的国内牌号是什么

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).
