What is EN 10025 S690QL1 high strength steel standard

The company has strict control on the quality of EN 10025 S690QL1 high strength steel. Each EN 10025 S690QL1 high strength steel is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the EN 10025 S690QL1 high strength steel meets the specified quality requirements.

Galvanized ASTM A36 steel angle Hot-dip galvanized steel angle is ideal for outdoor applications or corrosive environments where black EN 10025 S690QL1 high strength steel steel angles could be badly corroded in short time. The amount of galvanization is made according your requirements. Product description: Item: A36 Angle Steel. EN 10025 S690QL1 high strength steel Standard: ASTM A36. Technology: Hot Rolled.

The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for EN 10025 S690QL1 high strength steel.
