Relevance of TMP and Microalloying to Sustainable Production of Steel and Nonferrous Alloys

Oral Presentation

The global demand for heavy-gauge steel plates for infrastructure, wind-tower and line-pipe applications has increased in recent years, and this change in the consumption behavior intensified productivity challenges in rolling mills, particularly when conventional manufacturing strategies are not adapted to the evolving requirements and dimensions. Productivity in hot rolling is usually driven...

Relevance of TMP and Microalloying to Sustainable Production of Steel and Nonferrous Alloys

Oral Presentation

Nickel is an important alloying element in carbon steels, as it significantly enhances hardenability and toughness, particularly at low temperatures. It plays a key role in steel grades for demanding applications such as energy, mining, and defense. While most carbon steels contain less than 1 wt% Ni, cryogenic steels may include up to 9 wt%. In plate production—via normalizing, controlled...

62. Influence of NbC Precipitate Size Distribution on Pipe Seam/Girth Weld HAZ Austenite Grain Size Control in API X70 heavy gauge plates

Relevance of TMP and Microalloying to Sustainable Production of Steel and Nonferrous Alloys

Oral Presentation

Heavy‑gauge wide API X70 plates (25–28.2 mm) were developed at JSW Plate Mill through a combination of optimized Nb‑based microalloying, enhanced thermo‑mechanical controlled processing (TMCP), and accelerated Multi-Purpose Interrupted Cooling (MULPIC) cooling to achieve stable strength and low‑temperature ductility. Drop Weight Tear Test (DWTT) performance exceeded 85% shear at 0 °C for all...

21. Effect of Niobium Microalloying on Recrystallization Kinetics, Precipitation, and Mechanical properties in Low-Carbon, Low-Alloyed Steels

Relevance of TMP and Microalloying to Sustainable Production of Steel and Nonferrous Alloys

Oral Presentation

This study investigates the effect of niobium microalloying on the recrystallization kinetics, precipitation, and mechanical properties of low carbon steels. The experimental materials consisted of three laboratory cast and laboratory rolled steel grades, where the niobium content was the only variable. Used cooling method in these steels was coiling. The experimental work included a wide...

66. The Sustainable Production of Vanadium and its Application in TMP Steels and Other Alloys

Dr David Crowther (Vanitec)

Relevance of TMP and Microalloying to Sustainable Production of Steel and Nonferrous Alloys

Oral Presentation

Microalloying elements are of critical importance in the production of Thermo-Mechanically Processed (TMP) steels. Due to the high solubility of vanadium carbo-nitrides, V(CN), vanadium microalloying is suitable for a wide range of steels, ranging from ultra-low carbon automotive steels to medium carbon steels for forgings and reinforcing bar, high carbon rail steels and ultra-high carbon rod....

63. Effect of combined Nb-V microalloying in mechanical behavior of rebars

Relevance of TMP and Microalloying to Sustainable Production of Steel and Nonferrous Alloys

Oral Presentation

The achievement of yield strength levels above 460 MPa with ferrite-pearlite microstructures in medium carbon rebars requires, in addition to appropriate microstructural refinement, a certain contribution of precipitation strengthening. In addition to the minimum strength, a proper balance between TS and YS and good low cycle fatigue behavior can be other requirements that should be...
