Hardening (Heat treatment) Quenching - SlideShare

Mar 28, 2016 · Hardening (Heat treatment) Quenching 1. Hardening 2. Hardening treatment consist of heating to predetermined temperature usually known as hardening temperature ,holding at that temperature followed by rapid cooling such as quenching in water ,oil or salt water . High tensile strength and hardness can be achieved by this process. Hong Shuang Di Scientific.NetDevelopment of Direct Quenching Process for SPV490Q Steel Plate Authors:Gui Zhi Xiao, Kuai She Wang, Fu Xian Zhu, Hong Shuang Di Abstract:SPV490Q steel is a low alloy high strength structural steel plate used in the manufacture of oil storage tank.

Ironmaking NIPPON STEEL ENGINEERING

Direct-Reduced Iron Process (DRI) NIPPON STEEL ENGINEERING CO., LTD. provides new iron source technology that enables the achievement of productivity improvements, operational cost reductions, CO 2 emissions reductions, and capital investment reductions through the optimal combination of Tenova HYL and Danieli's natural gas-based direct-reduced iron Manufacturing Process / Major Equipment - Nippon SteelOut of all its numerous features, Nippon Steel Pipe is most proud of its integrated production control system covering tube manufacturing, drawing, heat treatment, and cutting. Whereas many steel tube manufacturers outsource the drawing process, this is yet another area where we exhibit our user-focused characteristics and commitment.

Microstructural development during the quenching and

Sep 01, 2011 · This paper presents a detailed characterization of the microstructural development of a new quenching and partitioning (Q&P) steel. Q&P treatments, starting from full austenitization, were applied to the developed steel, leading to microstructures containing volume fractions of retained austenite of up to 0.15. Microstructure and mechanical properties of 780 MPa high To develop an appropriate quenching process to produce Fe-0.9Mn-0.5Cr-2.4Ni-0.5Mo-C steel, the microstructures and mechanical properties of this steel were investigated under the direct quenching

Numerical simulation of immersion quenching process for

Abstract The present paper outlines the recently improved Computational Fluid Dynamics (CFD) model to simulate the immersion quench cooling process. The main application area of the presented method is heat treatment of cast aluminium parts, mostly cylinder heads in automotive internal combustion engines, where an accurate heat treatment prediction plays an important PRODUCT TECHNOLOGY - U.S. SteelU. S. Steel's Gleeble 3500 Thermomechanical Test System couples the ability to apply complex thermal and mechanical deformation cycles simultaneously to material specimens. The thermal cycle is controlled through direct-resistance heating via a computer-controlled time-temperature cycle. Concurrent to the thermal cycle, specimens can be deformed in tension or compression
