Product Introduction

60Si2Mn alloy spring steel is a widely used silicon-manganese spring steel, its strength, elasticity and hardenability are slightly higher than 55Si2Mn, and its chemical composition and mechanical properties are regulated by the Chinese national standard GB/T 1222-2007.

60Si2Mn is equivalent to A29M:2005 in the United States standard, EN 10089:2002 in Europe, and ISO 683-14:2004 in international standard.

60Si2Mn spring steel has the following general characteristics:

1)Low Carbon Content: 60Si2Mn spring steel belongs to the category of low-carbon alloy steel, cold extruded, carburized and hardened steel. The carbon content in 65Mn is generally in 0.56~0.6%, making it a low carbon steel suitable for welding and forming processes.

2)Excellent Flexibility and plasticity: After heat treatment and cold drawing hardening, the strength is relatively high, and it has certain flexibility and plasticity; under the same surface state and complete hardening, the fatigue limit is equivalent to that of the colorful alloy spring, exhibits good plasticity, allowing it to be formed into various shapes and structures without fracturing.

3)Heat treatment method: 60Si2Mn heat treatment methods include isothermal tempering, step quenching, sub-temperature quenching, high temperature tempering, and deformation heat treatment. The method can effectively improve the strength, toughness and service life of the 60Si2Mn spring steel.

4)Wide Application: 60Si2Mn spring steel is widely used in general structural and engineering purposes, including construction, bridges, machinery manufacturing, transportation equipment, high wear-resistant parts, and other industries where strength and durability are required.

60Si2Mn alloy spring steel is a widely used silicon-manganese spring steel, it has good flexibility and plasticity, springs and large and important coiled springs subject to alternating loads and operating under high stress. Some common applications of 60Si2Mn spring steel include:

1)High wear-resistant parts: such as grinding machine spindles, spring chucks, precision machine tool screws, cutters, knives and machetes, small-section flat springs, round springs, springs, collars on helical roller bearings, railway rails, etc. Its excellent comprehensive performance makes it a preferred choice for various mechanical applications

2)Machinery Manufacturing: 60Si2Mn spring steel is employed in the manufacturing of machinery and equipment components, such as frames, chassis, and structural parts. Its versatility and easy machinability make it a preferred choice for various machinery applications.

3)Automotive Industry: 60Si2Mn spring steel is utilized in the automotive industry for the production of components like car frames, chassis, and structural parts. Its high strength and good formability make it suitable for automotive applications.

  • Railway Vehicles: 60Si2Mn spring steel is also used in the manufacturing of railway vehicles, including railcar bodies, underframes, and structural components. Its mechanical properties and durability meet the requirements of the railway industry.

Classification By Size

The length is generally 2440mm, 2000mm, 3050mm, 4000mm, 3000mm, and the thickness is distinguished by cold rolling and hot rolling. Cold rolling mainly has thickness 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm. The main thickness of hot rolling is 3.0mm, 4.0mm, 6.0mm, 8.0mm, 10.0mm, and the width is generally 1000mm, 1219mm, 1500mm.Please contact customer service for general specifications.

Hot-rolled products have excellent properties such as high strength, good toughness, easy processing and good weldability, so they are widely used in manufacturing industries such as steel, construction, machinery, boilers, and pressure vessels. Application range: (1) After annealing, it is processed into ordinary cold rolling; (2) The galvanizing unit with pre-annealing treatment device processes galvanizing; (3) Panels that basically do not need to be processed.

Hot-rolled coils (in the form of flat plates or coils) generally have a thickness of 2.0-13.5mm, of which the price of 2.0-3.0mm hot coils gradually decreases from thin to thick; most steel mills have a basic price of 3.1mm-13.5mm Equivalent, the price of 3.1-4.0mm and 9.5mm-13.5mm hot plate coils in some manufacturers and markets may be higher than the price of 4.0mm-9.5mm plates. Hot plate coils represent products with a thickness of 5.5mm. Under normal circumstances, the price of flat plates is slightly higher than the price of coils.
