API 5L X70 steel pipe has a minimum yield strength of 70,300 psi or 485 Mpa. The current X70 steel pipe are all controlled micro-alloyed carbon-manganese steels. The micro-alloys elements are mainly Nb, V and Ti, and the total content of micro-alloys does not
High Strength Low Alloy Steel - IMOAMo in line pipe HSLA steel. Two technological developments made possible the successful launch of HSLA steel in large-diameter pipelines:the thermomechanical rolling process, and the use of niobium (Nb), vanadium (V) and titanium (Ti) as microalloying components.
Jul 19, 2013 · A thermomechanical control process consisting of slab reheating, controlled rolling, and accelerated cooling has been adopted at the plate mill, Bhilai Steel Plant, India for achieving high strength and toughness in CMn and microalloyed steels while keeping the mechanical properties and the flatness constant.

Progress in thermomechanical control of steel plates and Apr 03, 2012 · The water-cooled thermomechanical control process (TMCP) is a technology for improving the strength and toughness of water-cooled steel plates, while allowing control of the microstructure, phase transformation and rolling.
The water-cooled thermomechanical control process (TMCP) is a technology for improving the strength and toughness of water-cooled steel plates, while allowing control of the microstructure, phase transformation and rolling. This review describes metallurgical aspects of the microalloying of steel, such as niobium addition, and discusses advantages of TMCP, for example, in terms of weldability
S355M Thermomechanical Steel PlatesS355M Thermomechanical Steel Plates. Bridge made out of S355M structural steel plates from Dillinger. S355M is a thermomechanical rolled weldable fine grain structural steel to EN10025-4. We have a large stock of S355M from 10 100 mm. It has a steel number of 1.8834.
Standard Specification for Steel Plates for Pressure 1.1 This specification 2 covers steel plates produced by the thermo-mechanical control process (TMCP). The plates are intended primarily for use in welded pressure vessels. A description of the TMCP method is given in Appendix X1.
Steel cools as it is rolled, with a typical rolling finish temperature of around 750°C. The implementation of the thermomechanical rolling process (TMR) is an efficient way to achieve this. Designers should note that yield strength reduces with increasing plate or section thickness (thinner material is worked more than thick material
TMCP Steels IspatGuruNov 15, 2013 · The thermomechanical rolling process is characterized by deformation in the non-recrystallization region of austenite which may be carried up to an 80 % reduction in thickness so as to obtain the desired grain refinement. Fig 2 Comparison of conventional steel with TMCP steel. Rolling of Steel Plates in a Plate Rolling Mill; Pressure
Thermo-mechanical Rolling of S420M Steel Plates steel Thermo-mechanical Rolling of S420M Steel Plates steel plate. S420M material is hot rolled steel products for thermo-mechanical rolled weldable fine grain structural steel to EN 10025-4 standard. S means structural steel.
The water-cooled thermomechanical control process (TMCP) is a technology for improving the strength and toughness of water-cooled steel plates, while allowing control of the microstructure, phase
Thermomechanical tank technology Engineer LiveThe diagram shows that a thermo-mechanically rolled steel with a yield strength of 355 MPa, such as SA841-A-1 or P355ML2 (which are equivalent to normalised SA516-70 or SA537-1) can be easily welded with no preheating up to 40mm plate thickness, while the normalised grades would need a preheating in the range of 60-100°C.Thermomechanically rolled fine-grained structural steelsMechanically strong, tough and very easy to weld. Whether for the construction of pipelines, offshore platforms and wind-power installations, pressure vessels or other steel fabrications Dillinger's thermomechanically rolled plate convinces users with its high mechanical strength and toughness, combined with efficient workability and weldability.
