今天給各位分享c350l0是什么鋼的知識,其中也會對c250鋼進行解釋,現(xiàn)在開始吧!

澳大利亞牌號AS1163或AS350的鋼材對應的國內(nèi)牌號是什么?

c350l0是什么鋼(c250鋼)

as1163?你指的應該是grade?c350?RHS

下面是一些解釋

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?industry?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?during?the?coil?and?tube?manufacturing?process,?C350L0?steel?grade?is?available?in?the?following?ATM?tubular?products:

CHS

RHS

UniRail

StockRail

Other?sections?based?on?enquiry.

ATM?Grade?C350L0?steel?products?are?rated?to?meet?AS?1163?(Table?4)?Charpy?V-Notch?impact?test?requirements?at?the?test?temperature?of?0C?(i.e.?L0).?This?property?is?important?for?use?in?lower?temperatures?and?also?critical?for?non-brittle?behaviour?of?tubular?products?subject?to?dynamic?loads?–?particularly?for?thicker?sections?and

welded?connections.

The?mid-to-higher?strength?properties,?ductility?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.

Product?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?product.

Chemical?composition:?See?Table?4?which?applies?to?steelmake?cast?analysis?and?finished?product?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).

請問AS 3678-250、350和AS1163-C350L0 RHS對應的中國鋼號是什么?

AS 3678是鋼板的標準

AS 3678-250相當于Q235

AS 3678-350相當于Q345

AS1163為鋼管的標準

C350L0相當于Q345C

C350是什么材質(zhì)

馬氏體時效鋼是以無碳或超低碳Fe-Ni馬氏體為基體,經(jīng)過時效處理使金屬間化合物沉淀硬化的一種超高強度鋼。這類鋼的強度并不來自于碳,而來自于金屬間化合物的沉淀。

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(shù)值(單位KSI,1KSI=6.89476MPa)分為四個等級:

其中,00Ni18Co8Mo5TiAl,即18Ni(250),已經(jīng)納入我國國標GB/T 1299-2014《工模具鋼》中。

性能特點

上海秉爭實業(yè)有限公司18Ni鋼固溶以后形成超低碳馬氏體,硬度為28~30HRC,時效處理以后,由于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(yè)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,是制造航空航天和國防工業(yè)裝備的一種關鍵材料,在航空、航天、精密模具等工業(yè)領域獲得廣泛應用,目前在國內(nèi)外廣泛用作制造火箭發(fā)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。
