PLOW STEEL FOR A SNOW PLOW, AND METHODS FOR MANUFACTURING AND USING SUCH A PLOW STEEL

摘要

Plow steel (100) for a snow plow, comprising: a fastening means (110) for fastening the plow steel (100) to a snow plow; a main steel support plate (120), with a main plane extending across a width (W) and a height (H) dimension; and a surface contacting edge (130), running in the width (W) dimension along said steel support plate (120), which surface contacting edge (130) comprises a set of indentations (131) formed in the height (H) dimension in the metal support plate (120), hence forming a set of surface contacting teeth (132) along the surface contacting edge (130) and arranged between said indentations (131) along the width (W) dimension. The invention is characterised in that each of said teeth (132) comprises an insert (140) made of a wear-resistant material with better abrasive resistance than the steel material of said steel support plate (120), which inserts (140) do not cover said indentations (131) in a depth (D) dimension perpendicular to said main plane, and in that the steel support plate (120) comprises an elongated steel flange (150) covering said indentations (131) in the depth (D) dimension. The invention also relates to a manufacturing method and a use method.
