Development of High Strength Steel - Steel Exporter BeBon

Next, chemical composition and mechanical properties in the as welded and/or post weld heat treated condition need to be demonstrated,followed by a consumable classification according to AWS, EN or other. Influence of individual elements (like Mn,Ni, Mo, Ti or B) on weld metal toughness and strength level is discussed. Europäisches Patentamt[0026] The reasons for the above-indicated properties of the invention hot work tool steel have not been elucidated yet. However, it is speculated that the increased amount of N reacts with, e.g., Cr to form fine nitride, which in turn replaces fine secondary vanadium carbide and thereby refines crystal grains of the steel and improve the toughness

Ferrous abrasion resistant sliding materials and sliding

Oct 06, 2005 · And, in view of a concentration of carbon contained in hot work tool steels (SKD6, SKD7, SKD61, SKD62, SKD8 and 3Ni-3Mo steel) which requires high heat crack resistance, it is preferred that the upper limit of an amount of carbon which forms a solid solution with the ferrous abrasion resistant sliding material is set at 0.55 wt % and the lower Free-cutting tool steel - IshidaThe steel having such composition is referred to a material attaining a higher level of hardness based on high-carbon-content composition, and is suitable for cold forming die (e.g., cold press forming die, press punch, trimming die and die), cutting tool (e.g., knife, razor and saw blade), and impact-resistant tool (e.g., chisel and punch).

Hot Working Tool Steels Hitachi

A hot-work tool steel's functionality is defined by its chemical composition, the technology applied during production and by the ensuing heat treatment. In general, hot-work steels are of the medium and high-alloy type and most of them has relatively low carbon content (0.25 to 0.6%).
