澳大利亚牌号AS1163或AS350的钢材对应的国内牌号是什么？

as1163?你指的应该是grade?c350?RHS

下面是一些解释

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

ATM?Grade?C350L0?steel?products?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?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).
