鋼材RHS什麼意思

① RHS在鋼管中是什麼材質

RHS不是材質，是方管。

很多種材質的物質都可以形成方管體，它介質於，干什麼用，內用在什麼地方，大多數容方管以鋼管為多數，經過拆包，平整，捲曲，焊接形成圓管，再由圓管軋製成方形管然後剪切成需要的長度。

方管:：每米重量=(邊長+邊長)×2×厚×0.00785；

圓形管重量計算公式：{（周長÷3.14）-壁厚}*壁厚*0.02466。

(1)鋼材RHS什麼意思擴展閱讀：

方管以Q235熱軋或冷軋帶鋼或卷板為母材經冷彎曲加工成型後再經高頻焊接製成的方形截面形狀尺寸。具有綜合力學性能好，焊接性，冷，熱加工性能和耐腐蝕性能均好，具有良好的低溫韌性。

方管因為負荷的作用形式有拉伸、緊縮、蜿蜒、剪切等方式，因為強度也分成抗拉強度、抗壓強度、抗彎強度、抗剪強度等。

③ 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).

④ Q.H.S 和 R.H.S 在鋼結構中分別指什麼鋼材

經過查詢，鋼材截面形狀代號中QHS和RHS都代表方（矩）形中空鋼管，具體什麼差別還沒弄清楚

⑤ 進口鋼材里RHS縮寫代表什麼

RHS是代表進口鋼材中矩形鋼的縮寫，具體來說，R代表矩形，H代表中空，S代表型材。

矩形鋼在鋼材領域中屬於一種特殊的型材，其特點是橫截面為矩形，具有較高的機械性能和良好的耐腐蝕性。在實際應用中，矩形鋼廣泛應用於建築、橋梁、機械製造、航空航天等眾多領域。

在歐洲標准中，矩形鋼的常用牌號有S235JRH、S355J2H等，這些牌號的鋼材在性能上符合特定的質量要求。矩形鋼按照無縫鋼管和焊接鋼管的不同製造工藝，執行的國際標准包括EN10210-1、EN10210-2、EN10219-1、EN10219-2等。

通過這些標準的執行，確保了矩形鋼在生產過程中的質量控制和性能一致性。因此，在進口鋼材中，RHS是識別矩形鋼的重要標志，對於用戶和工程師來說，正確理解RHS的含義，有助於在設計、選材和應用過程中，選擇符合要求的矩形鋼產品。
