08X15H24V4TR — alloy Steel: Composition, Properties & Applications

Also known as: 08X15H24V4TR
(GOST 5632). Nominal values—confirm mill certificate.

CHEMICAL COMPOSITION
C:0.05-0.12;V:3.40-4.60;P:≤0.035;S:≤0.035

MECHANICAL PROPERTIES
Tensile:≥510 MPa;Yield:≥295 MPa;Elong:≥20%

TYPICAL APPLICATIONS
Low-alloy engineering steel with enhanced hardenability and strength from alloying elements. Vanadium (≈4%) refines grain and strengthens the tempered structure. Applied to gears, shafts, bolts, connecting rods, pressure parts and heavy forgings in automotive, energy and machinery sectors.

AVAILABLE FORMS
Bar,Plate

STANDARDS & EQUIVALENT GRADES
GOST 5632 08X15H24V4TR

HEAT TREATMENT
Typically normalized (880–920 °C, air cool) or carburized (900–930 °C) for case-hardening grades, then quenched and tempered at 150–200 °C.

PROCESSING PRECAUTIONS
Weldable with standard procedures; preheat may be needed for thick sections or higher-carbon/ alloy grades. Protect from decarburization during heating (controlled atmosphere or protective coating).
