The quality of A514 grade E quenched and tempered steel shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of A514 grade E quenched and tempered steel buyer, such as packaging, delivery time, etc.. On the basis of the quality of A514 grade E quenched and tempered steel in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of A514 grade E quenched and tempered steel and certain performance limit of A514 grade E quenched and tempered steel, etc.
The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. A514 grade E quenched and tempered steel, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest A514 grade E quenched and tempered steel processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain A514 grade E quenched and tempered steel by rolling method.
BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the A514 grade E quenched and tempered steel hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.
