High Strength Fine Grained Structural Steel

By adding different alloying elements, the high strength plate realizes the solid solution strengthening, grain boundary strengthening and second phase strengthening of the matrix structure, etc., and has successively appeared low alloy martensitic steel, bainite steel, austenite/bainite biphase steel, martensitic/bainite biphase steel, etc. In recent years, silicon has been used as the main alloying element to strongly inhibit carbide precipitation during bainite transformation.

Product Introduction

High strength fine grained structural steel

The characteristics of high-strength plate are mainly used in mining, construction machinery, strong wear and other environmental parts; Open pit shovel teeth, bucket teeth, excavator factory supporting shovel teeth, etc.; Vehicles, iron track, electric power, communication, machinery and equipment, mining machinery, gear, hydraulic equipment, transmission equipment, high strength standard parts, etc.; High strength bolts, wear-resistant wire mesh, coastal bridge steel bars and high strength equipment.

It can be obtained by carbide free bainitic ferrite and carbon, silicon stabilized residual austenite composed of austenite, due to the absence of carbide to eliminate cracks or spalling inducement, so it has excellent strength and toughness comprehensive mechanical properties, is the world's most favored new generation of wear-resistant materials, with the following advantages: yield strength, tensile strength and good ductility.
