R&D Update Hot-stamping boron-alloyed steels for ...

Hot stamping is compatible with boron-alloyed steel's chemical composition, because it creates a robust process window for quenching, which causes martensitic transformation. 1,2 Boron steels belong to a group of martensitic steels with good hardenability at low cooling rates.

Welding of Coated Steels : Total Materia Article

The E-XX12 or 13 will be used for welding thinner material, the E-XX10 or 11 will be used for welding galvanized pipe and for welding hot-dipped galvanized parts of heavier thickness. The low-hydrogen electrodes can also be used on heavier thicknesses. The welding technique should utilize slow travel speed to permit degassing of the molten metal.

Are Quenched and Tempered (Q&T) Steels Readily Weldable?

Also denoted by QT or Q/T, these steels are weldable, but care must be taken to adhere to established procedures at all times, as they often have high carbon contents, and thus high hardenability, leading to a hard heat-affected-zone (HAZ) and susceptibility to cracking. The BS EN 10277-5:2008 (old BS 970 Part 3) steels are good examples of these types of steel.

Hot Crack How it occurs and how it ... - Welding Engineers

The use of welding joints with a larger groove radius increases the width-to-depth ratio of weld metal, which prevents hot cracking, see Fig. 3. Use ferrite-controlled filler metals When welding austenitic stainless steels, use filler metals containing ferrite (normally 3-10% in weld metal) in the austenitic matrix.

Hot formed steels, - ScienceDirect

Hot forming is a special process for forming Mn-B alloyed steels (typically 22MnB5) into complex shapes. There are two methods to achieve this (1) Direct process the unformed blank is heated in a furnace, formed while it is hot ( in Fig. 12.2), and quenched in the die, and (2) Indirect process the blank is cold formed and trimmed ( in Fig. 12.2), heated, and quenched in the die.
