Product Description

Introduction

The main alloy elements of alloy steel include silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth, etc. Among them, vanadium, titanium, niobium, zirconium, etc. are strong carbide forming elements in steel. As long as there is enough carbon, they can form their own carbides under appropriate conditions. When there is no carbon or under high temperature conditions, they enter the solid solution as atoms; Manganese, chromium, tungsten and molybdenum are carbide forming elements, one part of which enters the solid solution in atomic state, and the other part forms replacement alloy cementite; Aluminum, copper, nickel, cobalt, silicon, etc. are elements that do not form carbides and generally exist in the solid solution in an atomic state.

Application

It is used to manufacture important quenched and tempered parts with good toughness, high strength and large size, such as shafts bearing high load in heavy machinery, turbine shafts, blades with diameter greater than 250mm, transmission parts with high load, fasteners (screws, bolts, studs, etc.), crankshafts, gears, etc; It can also be used for rotor shafts and blades with operating temperature exceeding 400 ° C. In addition, it can also be nitrided to manufacture important parts with special requirements. The steel has poor cold deformation property and good hot pressure processing property. Generally, the screw and bolt head are processed by hot upsetting. The cutting performance of the material is medium.

Heat treatment

Ac1 - lower critical temperature of heating, Ac3 - upper critical temperature of hypoeutectoid steel heating, Ms - martensite point, i.e. the starting temperature of martensite transformation
