Difference Between Hot and Cold Rolled Steel Metal

Sep 11,2014·Uses Hot rolled products like hot rolled steel bars are used in the welding and construction trades to make railroad tracks and I-beams,for example.Hot rolled steel is used in situations where precise shapes and tolerances are not required.Cold Rolled Steel.Cold rolled steel is essentially hot rolled steel that has had further processing.Effect of Hot Rolled Process on Microstructure and The impurities in steel are mainly sphericity,subspheticity of silicates and sulfuret,and the size of most impurities is smaller than 5m.The strength and toughness of X70 pipeline steel strips are high because of the fine acicular ferritic microstructure and low quantity of impurities.Effect of Rolling in the Recrystallization Temperature API X70 pipeline steel for the designed purpose is required to meet the API 5L supplementary requirements. - The normalized hot-rolled sample and the sample subjected to hot-rolling followed by quenching and tempering at 700 °C exhibited excellent mechanical properties because of the formation of the recrystallized ferrite microstructure

Effects of precipitates and inclusions on the fracture

In order to investigate the fracture toughness,crack tip opening displacement (CTOD) experiments were conducted on two X70 pipeline steel plates with different rolling processes.After the experiments,optical microscopy (OM),scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were employed to observe the microstructure and fracture morphology.Evolution of the microstructure and texture of X70 Jan 15,2016·In this work,all experiments were carried out on API X70 pipeline steel with an initial thickness of one half inch.The steel was received in as hot-rolled condition by EVRAZ Company,Canada.The chemical composition of the X70 steel is shown in Table 1.We rolled the specimens in the rolling direction at room temperature for an 80% Hydrogen induced cracking susceptibility in different In agreement with these findings,Mohtadi-Bonab et al.31 have reported that the trapping of hydrogen in manganese sulphide particles and the segregated band of hot rolled X70 pipeline steel

Material Design of Hot-rolled Steel Coils for Heavy Wall

Higher strength and toughness has been required for linepipe steels using for long-distance pipelines of natural gas transportation.To achieve high strength and drop weight tearing test properties for heavy wall X70 spiral linepipes,the microstructure refinement of bainitic ferrite is essential in hot-rolled steelMaterial Design of Hot-rolled Steel Coils for Heavy Wall Higher strength and toughness has been required for linepipe steels using for long-distance pipelines of natural gas transportation.To achieve high strength and drop weight tearing test properties for heavy wall X70 spiral linepipes,the microstructure refinement of bainitic ferrite is essential in hot-rolled steel coils.Pipeline Steel Hot Rolled 304 Stainless Steel Coil X42 X4 High quality Pipeline Steel Hot Rolled 304 Stainless Steel Coil X42 X4 X52 X56 Grade from China,China's leading Hot Rolled Steel Coil product market,With strict quality control Hot Rolled Steel Coil factories,Producing high quality Pipeline Steel Hot Rolled 304 Stainless Steel Coil

Role of texture and inclusions on the failure of an API

The microstructure of API X70 pipeline steel was modified by applying different heat treatments including water-quenched,water-sprayed,and water-quenched and tempered.Some results are removed in response to a notice of local law requirement.For more information,please see here.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextPressure Vessel Hot Rolled API 5L X70 Pipeline Steel Plate X70 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X70 steel with the demands in mechanical properties of the pipes followed the API specification for grade X70 (YS is 485MPa,TS is from 600-750 MPa).It is well Pressure Vessel Hot Rolled API 5L X70 Pipeline Steel PlateA516 Gr.55 steel plate for Boiler steel and pressure

Steel prices reach levels not seen since 2008

Hot-rolled steel prices have reached levels not seen since in 13 years.Pricing is expected to fall below the $1,000/ton mark,but that might not be until late 2021.Now steel buyers arelink.springerThe development of inhomogeneity in the microstructure,texture,and mechanical property in hot-rolled (API) 5L X70 pipeline steel after rough and finish thermomechanical control processing has been investigated by experimental measurements.
