120ksi

Designed for applications demanding a minimum tensile strength of 120 Ksi and excellent Charpy V-notch toughness, these consumables are suitable for diverse structural uses. From lifting machines to shipbuilding, railway sectors to crane fabrication, they find application in various high-strength scenarios. Preheat as per base material and thickness; generally, a 100°C minimum preheat is needed for materials requiring these high-strength consumables. Exercise caution with some HSLA steels, as interpass temperatures above 200°C may compromise strength and toughness. Post-weld heat treatment (PWHT) depends on the base material and application.

Mn-Ni-Mo low alloy consumables for welding high strength steels with ultimate tensile strength up to 825 MPa (120 ksi).

The microstructure of all the consumables is predominantly ferrite; some will contain high proportions of acicular ferrite for optimum aswelded toughness

This material is used for a variety of high strength steels. HY-80, HY-90, HY- 100. S890 and higher strength grades, thermo mechanically treated fine grain steels.
