An iron-boron alloy powder or an iron-boron alloy powder composition suitable for remediation of halogenated hydrocarbon polluted soil, water or groundwater as well as the use of the powder or powder composition. The boron-iron alloy powder suitable for remediation of polluted soil or waters may have 0.1-40% by weight of boron and inevitable impurities up to a content of 10% by weight. Further, a method for remediation of halogenated hydrocarbon polluted soil, water or groundwater.

Powder, powder composition, method for use thereof and use of the powder and powder composition

The invention concerns a new pre alloyed steel powder comprising in addition to iron and inevitable impurities, by wt %, 1.3-1.7% by weight of Cr, 0.15-0.3% by weight of Mo, 0.09-0.3% by weight of Mn, not larger than 0.01 by weight of C, not larger than 0.25% of O.

Pre-alloyed iron based powder

The invention concerns a metal powder composition for warm compaction comprising an iron-based powder and lubricant powder consisting of a polycarboxylic acid amide wax having a melting point peak in the range of 180&deg; to 210&deg; C.
