钢材RHS什么意思

① RHS在钢管中是什么材质

RHS不是材质，是方管。

很多种材质的物质都可以形成方管体，它介质于，干什么用，内用在什么地方，大多数容方管以钢管为多数，经过拆包，平整，卷曲，焊接形成圆管，再由圆管轧制成方形管然后剪切成需要的长度。

方管:：每米重量=(边长+边长)×2×厚×0.00785；

圆形管重量计算公式：{（周长÷3.14）-壁厚}*壁厚*0.02466。

(1)钢材RHS什么意思扩展阅读：

方管以Q235热轧或冷轧带钢或卷板为母材经冷弯曲加工成型后再经高频焊接制成的方形截面形状尺寸。具有综合力学性能好，焊接性，冷，热加工性能和耐腐蚀性能均好，具有良好的低温韧性。

方管因为负荷的作用形式有拉伸、紧缩、蜿蜒、剪切等方式，因为强度也分成抗拉强度、抗压强度、抗弯强度、抗剪强度等。

③ 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).

④ Q.H.S 和 R.H.S 在钢结构中分别指什么钢材

经过查询，钢材截面形状代号中QHS和RHS都代表方（矩）形中空钢管，具体什么差别还没弄清楚

⑤ 进口钢材里RHS缩写代表什么

RHS是代表进口钢材中矩形钢的缩写，具体来说，R代表矩形，H代表中空，S代表型材。

矩形钢在钢材领域中属于一种特殊的型材，其特点是横截面为矩形，具有较高的机械性能和良好的耐腐蚀性。在实际应用中，矩形钢广泛应用于建筑、桥梁、机械制造、航空航天等众多领域。

在欧洲标准中，矩形钢的常用牌号有S235JRH、S355J2H等，这些牌号的钢材在性能上符合特定的质量要求。矩形钢按照无缝钢管和焊接钢管的不同制造工艺，执行的国际标准包括EN10210-1、EN10210-2、EN10219-1、EN10219-2等。

通过这些标准的执行，确保了矩形钢在生产过程中的质量控制和性能一致性。因此，在进口钢材中，RHS是识别矩形钢的重要标志，对于用户和工程师来说，正确理解RHS的含义，有助于在设计、选材和应用过程中，选择符合要求的矩形钢产品。
