For minimum reduction ratio or minimum thickness deformation ratio of rolled and forged products, see C.8. 6.2 Treatment and surface condition at delivery 6.2.1 Treatment condition The treatment and heat-treatment condition (if any) at the time of delivery must comply with the condition agreed in the order and shall be one of the conditions indicated in Table 1. Bright steel products in cold drawn or peeled/turned condition are coated with a light film of grease from processing, for bright steel products in a finally heat treated condition the manufacturer chooses the rust protection after heat treatment. The usual light application of ordinary grease or oil does not afford positive protection against rusting, particularly in the presence of condensation water. The use of a selected rust inhibitor or a special type of packing shall, if required, be agreed at the time of enquiry and order, see C.9. 6.2.2 Particular surface conditions Table 2 shows the possible surface conditions and tolerance classes according to ISO 286-2 at delivery. 6.3 Traceability of the cast Each product shall be traceable to the cast, see Clause 10. 7 Requirements 7.1 Chemical composition, mechanical properties and hardenability 7.1.1 General Combination of usual treatment conditions at the time of delivery and requirements concerning chemical composition and mechanical properties are shown in Tables 1. SIST EN 10277:2018
¶ 150 mm may have an undefined profile within a distance of 0,2 mm of the hypothetical edge, flats in widths > 150 mm within a distance of 0,5 mm, unless otherwise agreed. For widths > 150 mm, the corner profile may be undefined within a distance of 0,5 mm of the hypothetical edge, unless sharp corners have specifically been ordered. 7.8 Surface quality Bright products shall have a smooth, scale free surface. Bright products in the final heat treated condition shall be free from loose surface scale; their surface might be discoloured or darker. For hexagons, squares, flats and profiles with special cross-sections, one cannot achieve – for manufacturing reasons – the same quality of surface finish as for round cross-sections. Since surface discontinuities (cracks, overlapping, scale, isolated pores, pits, grooves, etc.) cannot be completely avoided during manufacturing (hot and cold forming, heat treatments, handling and storage) and since they are retained after drawing, agreements shall be made regarding surface quality. The surface quality of the products shall be one of the classes according to Table 3. Cold drawn products are normally delivered in class 1, while turned and peeled bars as well as ground round bars are delivered in class 3. Different classes may be agreed at the time of enquiry and order. For flats, squares in sizes greater than 20 mm and hexagons in sizes greater than 50 mm, the maximum possible depth of surface discontinuities shall be agreed at the time of enquiry and order. NOTE Where automatic testing of the surface is applied, 50 mm of each end of the bar is not normally covered. Surface defects cannot be eliminated without removal of material. Products in the 'technically crack free by manufacture' condition are only available in the peeled/turned and/or ground conditions. 8 Inspection 8.1 Testing procedures and types of inspection documents 8.1.1 Products complying with this standard shall be ordered and delivered with one of the inspection documents specified in EN 10204. The type of document shall be agreed upon at the time of enquiry and order. If the order does not contain any specification of this type, a test report 2.2 shall be issued. 8.1.2 If, in accordance with the agreements made at the time of enquiry and order, a test report 2.2 is to be provided, this shall cover the following information: a) confirmation that the material complies with the requirements of the order; b) results of the cast analysis for all elements specified in Tables A.1 to A.4 for the steel grade concerned. 8.1.3 If in accordance with the agreements in the order an inspection certificate 3.1 or 3.2 to EN 10204 is to be provided, the specific inspections and tests described in 8.3 and 9 shall be carried out and the results shall be confirmed in the inspection certificate.

The article discusses the technical delivery conditions for bright steel bars. These bars are used for mechanical purposes, such as machine parts. The document specifies different types of bright steel, including general engineering steels, free-cutting steels, case-hardening steels, and steels for quenching and tempering. The mechanical characteristics are listed for products up to 100 mm thick, while larger dimensions require agreement between the manufacturer and purchaser. The document does not cover cold rolled products or cut lengths from strip or sheet. Stainless steel bright steel products are covered in a separate document. The general technical delivery requirements of EN 10021 also apply.
기사 제목: EN 10277:2018 - Bright steel products - Technical delivery conditions 기사 내용: 이 문서는 인출, 껍질제거/조립 또는 연마 상태의 밝은 강철 바에 대한 기술적 납품 요구 사항을 명시합니다. 이는 기계 부품과 같은 기계적 용도를 위해 사용되며 밝은 바는 다음과 같은 강철 유형으로 구분됩니다: a) 비합금 일반 공학 강철; b) 비합금 가공 편심강; c) 비합금 및 합금 재경화 강철; d) 비합금 및 합금 단락 경화 강철. 이 문서는 100mm까지의 두께에 대한 제품의 기계적 특성을 목록화합니다. 큰 크기의 경우, 제조업자와 구매자는 문의와 주문 시 기계적 특성에 대해 합의합니다. 이 문서는 도마끼거나 절삭해서 생산된 스트립이나 시트에서 제작된 냉간압연 제품 및 절단 길이를 다루지 않습니다. 스테인리스 강철의 밝은 강철 제품은 EN 10088-3에서 찾을 수 있습니다. 이 문서 외에도 EN 10021의 일반적인 기술적 납품 요구 사항이 적용됩니다.
記事タイトル：EN 10277：2018 - ブライトスチール製品 - 技術的な納入条件 記事内容：この文書では、引き抜かれたもの、剥がされたもの/回転されたもの、または研磨された状態のブライトスチールバーに対する技術的な納入要件が規定されています。これらは、機械部品などの機械的な目的で使用されるものです。ブライトバーは以下の鋼種に分類されます： a）非合金の一般工学用鋼; b）非合金の切削加工用鋼; c）非合金および合金の測硬鋼; d）非合金および合金の焼入れ焼戻し用鋼。 この文書では、厚さ100mmまでの製品の機械的特性がリストされています。大きな寸法の場合は、製造業者と購入者が問い合わせと注文時に機械的特性について合意します。 この文書は、ストリップまたはシートから切断された冷間圧延製品や切断長さは対象としていません。ステンレス鋼のブライトスチール製品はEN 10088-3に記載されています。 また、この文書に加えて、一般的な技術的納入要件であるEN 10021も適用されます。
