discovered. This microstructure was named by Bian’s colleageus at the United States Steel Corportion. At first microstructure of martensite and bainite seem similar‚ which had many aspects on their transformation of mechanisms. Microstructure of bainite seems to be darker than the mastenisite under a microscope. The reason behind bainite structure became useful was because of its hardness. There are few Heat treatments that steel can be tested by such as Annealing‚ quenching Harderning‚ and Normalizing.

Ms Sanghamitra‚ R&D Refractory Department from TATA STEEL‚ Jamshedpur‚ gave a talk on “STEEL MAKING REFRACTORY”‚ on 12th September 2012 at 11:00 AM at Ceramic Engineering department. Process chart of TSL‚ INDIA was first addressed. So‚ it all starts with iron ores and fluxes (limestone) to be mixed and then pelletized in a sinter plant. At the same time‚ raw coal is processed to form coke in a coke plant and then sintered pellets along with coke are fed to a blast furnace. Hot metal is obtained

1.0 INTRODUCTION: AISI 304L austenitic stainless steel is widely used as engineering materials due to its high strength and good corrosion resistance properties. However‚ AISI 304L stainless steel undergoes extensive wear and erosion when applied as components in aggressive environments such as petro- chemical and marine atmosphere [1]. Solid particle erosion is defined as the progressive loss of material from a solid surface due to mechanical interaction between the surface and some fluid entrained

The Classification of Steel Ball There are two kinds of steel ball‚ casting steel ball and forging steel ball. Casting ball manufacturers mix scrap steel‚ scrap metal and other waste metals in intermediate frequency electric stove for heating so as to fully melting. Right amount precious metal alloy‚ such as ferrochrome‚ ferromanganese‚ vanadium iron are added in melting process. When temperature is above 1550 ℃‚ powering hot metal to the steel mold or mold steel ball production line. This kind

India’s Steel Industry is more than a century old. Before the economic reforms of the early 1990s the Indian steel industry was a predominantly regulated one with the public sector dominating the industry. Tata Steel was the only major private sector company involved the production of steel in India. SAIL and Tata Steel have traditionally been the major steel producers of India. In 1992‚ the liberalization of the India economy led to the opening up of various industries including the steel industry
