What is chemical composition and mechanical properties of 34crmo4 steel for fastener

The company is committed to providing customers with high-quality and low-cost 34crmo4 steel for fastener steel products as the goal, striving to create value for customers as its own responsibility. With advanced Kaiping processing equipment and strong logistics distribution system, the company can meet the needs of customers at any time. The company has the advantages of 34crmo4 steel for fastener complete specifications, low price and fast distribution, With the service concept of keeping promise and valuing quality, it has won the trust and unanimous praise of the majority of users. The scale and strength of the enterprise is in the forefront of domestic metal material business units.

34crmo4 steel for fastener, 45Mn2 steel is a kind of alloy structural steel. 45Mn2 steel is made of high-quality carbon structural steel with proper addition of manganese. 45Mn2 steel belongs to the medium carbon quenched and tempered steel in alloy structural steel. The parts made with 45Mn2 steel can obtain high strength and good toughness after quenching and tempering at high temperature. That is to say, 45Mn2 steel has good comprehensive mechanical properties and is often used to manufacture shafts, connecting rods, fasteners which bear large loads.

34crmo4 steel for fastener and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of 34crmo4 steel for fastener and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.

The main raw material of 34crmo4 steel for fastener, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.
