JIS SKD61 HOT WORK TOOL STEEL

JIS SKD61 is a kind of tool steel (also known as AISI H13 steel or just H13[1]) is a tool steel grade standardised for hot working. The main feature of this grade is the combination of alloyed elements of chromium, molybdenum and vanadium, Cr-Mo-V, which provides a high wear resistance to thermal shock. It is well known as for its great strength, and heat resistance. It is heavily used for die casting in the cold heading field. The presence of high vanadium in DIN 1.2344 can handle the abrasion at both low and high temperatures. It always provides a uniform and high level ofmachinability. This tool steel is mostly used for aluminum, magnesium and zinc die casting.

Properties:

SKD61 steel is Cold Work Steel with High Carbon High Chromium contents.
It has high wear resistant and toughness properties  skd61 is the superior steels than D3 due to high alloys properties.
