XML15MnVB cold heading steel is a low-carbon boron microalloying spring steel specially designed for cold heading. It has I grade in quenched and tempered. The original M grade hot-rolled strip steel is advanced after being improved by MPIL.

XML15MnVB is characterized by high surface quality, high strength and high hardness, so it is especially suitable for the production of complex shape, small parts and high precision connection elements. It is mainly used in the production of bolts and screws.

XML15MnVB cold heading steel is mainly used for cold heading and cold pressing process of various fasteners, such as automobile parts, electronics parts and communication parts. The structure of the surface is uniform and tight, the performance is stable and reliable, and the mechanical function is stable. Its strength and plasticity are balanced, and it can be used to make small parts with high strength, surface hardening and tempering.

The chemical composition of XML15MnVB cold heading steel is C 0.14-0.20%, Mn 1.15-1.60%, B 0.0005-0.0060%, Si 0.040-0.80%, P ≤ 0.035%, S ≤ 0.035%. The yield strength is 207MPa and the tensile strength is 470-630MPa.

When processing XML15MnVB cold heading steel, pre-heating before welding and very high temperature heat treatment after welding must be done. When cold heading, the temperature of the steel rod should be 275-400℃ and the upsetting force should be greater than 28KN. The die should be designed reasonably, the depth and polishing degree should meet the requirements, and the workpiece and the die should be coated with anti-adhesive agent.
