Metalfer answers in Europe the most important car manufacturers and the most important suppliers of original equipment made in Metalfer.
The achievement of particular roughness values, largely below the regulations of use. Success factor and development for Metalfer.
In addition to the steel quality reported in the EN 10305-2 standard, microalloyed steel pipes can be produced, provided they are produced in industrial batches.

The particular sector of gas springs, in continuous development, is constantly monitored and assisted by the prestigious Metalfer products.

DIMENSIONAL RANGE

AUTOMOTIVE

Automotive sector strategic, represents for the METALFER group 50% of the whole activity.

METALFER reaches in Europe the most important car manufacturers and the most significant original equipment suppliers.

TOLERANCES: The tolerances obtainable on pipes in supply condition + C, in the dimensional range shown in the table, are about half of those indicated by the EN 10305-2 standard.

STANDARDS: on request the pipes can be produced according to the requirements of the main international standards or according to the customer specifications.

SURFACE APPEARANCE: The drawn tubes for mechanical use generally have a good internal and external surface; only slight surface defects are allowed as long as they are within the thickness tolerances. Phosphating residues, drawing and protective lubricants may be present; on request it is possible to eliminate them.

TESTS AND TESTS: Visual, dimensional, mechanical tests, chemical analysis. During the final check phase, the pipes can be subjected to 100% non-destructive tests: Eddy current, Ultrasonic, leakage flow.

TESTING CERTIFICATES: if required a test certificate can be issued according to EN 10204.

SUPPLY STATUS: + C (raw), + LC (semicrudo), + SR (extended), + A (annealed), + N (normalized).

HYDRAULICS

The presence of METALFER in the hydraulic sector and in particular of the "ready to use" polished pipe constitutes the second most important market for the whole group.

The achievement of particular roughness values, largely below the regulations of use are the success factor and development for METALFER.

MECHANICS

The wide dimensional range, the narrow tolerances, the surface aspects and the diversification of the offered components allow METALFER, a significant presence in the precision mechanics sector.

In addition to the steel quality reported in the EN 10305-2 standard, microalloyed steel pipes can be produced, as long as in industrial batches, such as: 26MnB5 - 28Mn6 - 34Mn - 30CD4.

At the customer's request it is possible to obtain mechanical characteristics different from the tabular ones.
