- YC INOX will replace product or credit the cost for product, on product which fails to meet customer fabrication requirements due to raw material failure, provided that the material chemical or mechanical properties fall outside the requirements indicated on the customer purchase order.
- YC INOX is not responsible for failure of raw materials related to improper Customer fabrication and processing, which leads to wrinkling, etc.
正面
- Unless otherwise specified on the customer order, the top surface of plates, and sheets, or the outside surface of coiled products is considered the prime surface. [12]
錆び／汚れ
- YC INOX will evaluate all rust and stain claims to determine cause. YC INOX will not accept any claim for transit rust or stain related to improper storage or handling in a customer's facility.
- Responsibility according to this claim policy is limited to rust which has attacked the surface of the material, leaving pits or other surface condition nonconformance.
- Claims are subject to review for proper transporting and storage.
- YC INOX products must be stored in dry areas and protected from high humidity and surface contamination from water, lubricants, and other liquids.
- Claims for rust on products where the customer has requested to limit or disallow the use of rust preventatives will not be honored.
- Claims for rust on products that have already been fabricated by the customer or shipped to another location will be subject to investigation by YC INOX.
- YC INOX will not be responsible for rust on products that have been subjected to processing or handling operations, which disturb the rust preventive properties.
寸法
- Requirements for dimensions will be according to customer specifications or purchase order accepted prior to production by YC INOX in writing, and/or consistent with applicable international specifications (ASTM, EN, JIS, etc.). [2]
- However, YC INOX will provide our product within customer specified tolerance if agreement to provide this product is acknowledged in writing prior to order acceptance by YC INOX.
外観形状について
- YC INOX’s responsibility according to this claim policy is limited to surface conditions that do not meet the requirements of the applicable international standard.
- When customer requirements demand a product that exceeds these standards, YC INOX must agree, in writing, to provide the material to the customer requirements.
- Where product does not meet either the international specifications (ASTM, JIS, EN, etc.) or the written undertaking of YC INOX, claims for shape defects will be considered.
- Claims for surface condition defects are subject to review for damage during transportation or storage.
- Claims for surface condition defects that have already been fabricated by the customer or shipped to another location will be subject to investigation by YC INOX.
- YC INOX will not honor claims for visible defects found at an end user on material that has been processed and inspected at a downstream operation. These defects might include dimensions, roll marks, scale or other surface issues.
鋼板／鋼帯
- Slight surface imperfections, inherent in the rolling process, are permitted. When products are delivered in coil form, the degree and extent of such imperfections may be expected to be greater, due to the impartibility of removing short lengths of coil. [12]
- If a defect is visible at the beginning of an individual coil, we authorize the processing of up to 10% of the coil weight to evaluate the degree and persistence of the defect.
- If the defect diminishes at the 10% point, we authorize the processing of up to an additional 5% of the coil weight. If the defect persists, the balance of the coil, along with the metal processed must be set aside for our inspection.
- Shape claims should include evidence of the pre-processed coil. This evidence will be as received before leveling or slitting of the material.
- Claims will not be honored for coil O.D. and I.D. wraps.
- Cold rolled sheets should be free of imperfections such as roll marks, sliver, rolled in scale, scratch-gouge marks, pickle stain and seam defects Flat products with No.1 finish or hot-roll anneal or hot-roll anneal and pickle finish it is permitted to grind to remove surface imperfections, provided such grinding does not reduce the thickness or width at any point beyond the permissible variations in dimensions. [7]
- Repair of surface defects of plate, by welding, is permitted unless prohibited by other specifications or purchase order requirements. Defect depth shall not exceed 1⁄3 of the nominal thickness, and the total area shall not exceed 1 % of the plate surface area, unless prior approval from the customer is obtained. After repair welding, the welded area shall be ground smooth and blended uniformly to the surrounding surface. [8]
パイプ／チューブ
- Tubular products shall be uniform in quality and condition and have a finish conforming to the standard. Surface imperfections such as handling marks, straightening marks, light mandrel and die marks, shallow pits, and scale pattern will not be considered injurious or defects if the imperfections are removable within the tolerances specified for wall thickness. [9], [10], [11]
平坦度／反り
- YC INOX guarantees all sheet/plate product supplied will be within flatness tolerance as defined in international specifications (ASTM, JIS, EN, etc.).Flatness or edge wave is the maximum distance between the lower surface of the product and the flat horizontal surface, without any erect measurement.
- When customer requirements are more stringent than the aforementioned standard, YC INOX will provide product, as agreed in writing.
- When YC INOX provides a product that exhibits flatness/edge wave greater than either the agreed standard or international specifications (ASTM, JIS, EN, etc.), and the product is unsuitable for the designated end use, YC INOX will consider claims for flatness /edge wave.
ヒートカットによる変形
- YC INOX guarantees all sheet/plate product supplied will be within flatness tolerance as defined in international specifications or accepted in writing by YC INOX. Claims of thermal* cutting distortion will not be honored.
* Distortion from laser processing is a result of the sudden rise in temperature of the material near the cutting zone. Distortion is also created by the rapid solidification of the cutting zone. In addition, distortion also can be attributed to the rapid solidification of material remaining on the sides of the cut.【14】
溶接部の完全性
- According to this claim policy for weld failure YC INOX’s responsibility is limited to material that fails in the weld seam area when tested as specified in the latest edition of the international specification.
- Claims for weld seam failures during customer processing are subject to review for appropriate fabrication practices, tooling and end cut condition.
製品表示
- Unless otherwise specified on the customer order, the method of marking and the material of marking for shipment shall be in accordance with the YC INOX’s procedures. Its quality shall be durable for at least one year in unheated and covered storage. Corrosion resistance of the product shall not be impaired by the marking. For flat products, one surface of the product shall be marked. This will normally be the prime surface of products, where only one surface is guaranteed to the required standard. As an alternative, for items that are wrapped, bundled or boxed, or where the surface is ground or polished, the marking may be applied to the packaging, or to a tag securely attached to it. [13]
訳あり製品
- Secondary product is sold without any warranty. The secondary product will be represented prior to sale with defects but this may not be all inclusive of the defects in the product.
