Product Overview
Cmr Group offers a wide range of cold-drawn seamless pipes and chromed bars for hydraulic and pneumatic applications. These products are available in various diameters and specifications to meet diverse industrial needs.
Available Diameters and Specifications
The document provides detailed tables listing the available diameters, thicknesses, and weights of the pipes and bars. For example, pipes range from internal diameters of 30mm to 400mm with corresponding external diameters and weights. Chromed bars are available from 4mm to 150mm in diameter.
Mechanical Properties
The mechanical properties of the materials used are specified, including tensile strength (Rm), yield strength (Re), and elongation (A5). For instance, the Fe510-D material has a tensile strength of ≥580 N/mm² and a yield strength of ≥355 N/mm².
Chemical Composition
The chemical composition of the materials is detailed, with maximum percentages for elements like carbon, manganese, silicon, phosphorus, and sulfur.
Tolerances and Finishing
The document outlines the tolerances for external and internal diameters, internal roughness, and straightness. For example, external diameter tolerances are according to DIN 2393 and ISO standards.
Chrome Plating Specifications
Specifications for chrome plating include chrome thickness, exposure hours in saline fog, and microhardness. Type 200 chrome has a thickness of ≥20µm and a microhardness of 900 - 1050 HV.
Additional Processing and Packaging
Cmr Group offers additional processing such as turning, milling, and cutting to size. Packaging ensures product integrity, with oil used for internal pipe protection and external protection for chromed bars. Special supply conditions can be arranged upon request.
