In our industry, we adhere to a wide range of international and regional standards that ensure material quality, consistency, continuity of supply, and suitability for specific applications. Why are these standards important?<\/strong><\/p>\n<\/div>

  • <\/i><\/span>
    \n

    They ensure material quality and properties<\/strong> \u2013 Each standard guarantees mechanical, thermal, and corrosion properties.<\/p>\n<\/div><\/li>

  • <\/i><\/span>
    \n

    They promote global compatibility<\/strong> \u2013 They enable easy exchange of materials between industrial sectors.<\/p>\n<\/div><\/li>

  • <\/i><\/span>
    \n

    They define processing requirements <\/strong>\u2013 Delivery condition standards optimize machinability, heat treatment, and formability.<\/p>\n<\/div><\/li>

  • <\/i><\/span>
    \n

    They guarantee safety and compliance with regulations<\/strong> \u2013 Key for aviation, energy, construction, and medical applications.<\/p>\n<\/div><\/li><\/ul>

    We offer deliveries of materials in accordance with the requirements of EN, ISO, DIN, \u010cSN, GOST<\/strong>, and other technical standards. Products and semi-finished products can be shipped in various delivery conditions (annealed, hardened and tempered, normalized annealed, in a state after solution annealing, nitrided, etc.) and in accordance with the requirements of the specific application. Each delivery can be accompanied by the relevant inspection document in accordance with EN 10204:2004<\/strong>, including:<\/p>\n<\/div>

    <\/div>
    \n

    2.1 \u2013 Declaration of conformity, 2.2 \u2013 Protocol on the results of unverified tests<\/p>\n

    3.1 \u2013 Certificate of specific test results performed by the manufacturer<\/p>\n

    3.2 \u2013 Certificate approved by an independent testing organization. In the case of international deliveries or the need for state supervision, documentation may also be issued in accordance with ISO 10474. This ensures full traceability of origin, monitoring of material flow during production, verifiability of mechanical and chemical properties, and compliance with legislative and customer requirements in a wide range of industries \u2013 from energy and chemicals to transportation, aviation, and medical technology.<\/p>\n<\/div><\/div><\/div>
