SIST EN 2103-2:2001

Overview

SIST EN 2103-2:2001 is a European standard published by CEN, titled Aerospace series - Steel, nickel base and cobalt base alloy remelting stock and castings - Technical specification - Part 2: Remelting stock. This standard defines the specific requirements for remelting stock intended specifically for the production of steel, nickel base, or cobalt base alloy castings used within the aerospace industry. It is designed to be used in conjunction with EN 2103-1, ensuring consistent quality and technical criteria across remelting stock and casting processes.

The scope of EN 2103-2 focuses on remelting stock materials that are critical for high-performance aerospace components requiring exceptional strength, durability, and corrosion resistance. This standard supports manufacturers and suppliers by setting uniform specifications that promote safety, reliability, and compatibility in aerospace material production.

Key Topics

The standard covers several important aspects surrounding remelting stock materials including:

• Material Composition: Specifications for steel, nickel base alloys, and cobalt base alloys used as remelting stock.
• Quality Requirements: Mechanical and chemical property criteria that must be met to ensure material integrity.
• Manufacturing Controls: Guidelines on processes such as melting, refining, and casting to maintain consistency.
• Test Methods: Defined procedures for evaluating remelting stock properties to confirm adherence to technical specifications.
• Traceability and Documentation: Requirements for documentation and product marking to ensure traceability throughout the supply chain.

By standardizing these elements, EN 2103-2 helps ensure that only materials meeting rigorous aerospace standards are used for critical component manufacturing.

Applications

EN 2103-2 is essential in various aerospace manufacturing and engineering contexts, such as:

• Production of aerospace engine components where high-temperature resistance and material integrity are crucial.
• Manufacture of structural aerospace parts that require outstanding mechanical strength and corrosion resistance.
• Use by material suppliers and remelting facilities to qualify and certify their steel, nickel, and cobalt base alloy stocks.
• Adoption by quality assurance teams managing raw material inspection and control in aerospace supply chains.
• Integration in aerospace research and development focused on new alloy formulations and remelting techniques to enhance performance.

This standard supports the aerospace industry's goals for safety, efficiency, and performance by ensuring that remelting stock materials consistently meet international quality benchmarks.

Related Standards

For comprehensive aerospace alloy specifications, EN 2103-2 should be used alongside the following:

• EN 2103-1: Technical specification for castings of steel, nickel base and cobalt base alloys, complementing the remelting stock standards.
• Other aerospace material and quality management standards governing alloy processing, testing, and certification.
• Industry-specific standards addressing environmental, mechanical, and fatigue requirements relevant to aerospace components.

Together, these standards create a robust framework governing the production and use of steel and alloy materials critical to aerospace manufacturing.
