・Normal (rei ten rei rei rei ichi milli)
・Manufacturing Industry (man bun no ichi milli/ konma ichi micron/ rei ten ichi micron)
"〇 bun no 1 millimeter "is the idea of how many millimeters are when 1 mm is divided by 100, 1000, and 10000.
On the other hand, "〇 micron" is based on the assumption that 1 micrometer is 0.001 mm.
(In manufacturing, microns are used more than micrometers.)
▼The common conversion relationships are as follows
0.1mm = 100㎛
0.01mm = 10㎛
0.001mm = 1㎛
0.0001mm = 0.1㎛

◆What's Matrix High-Speed Steel?
It has excellent toughness due to its low carbon content.
◆Proterial's Matrix Steel Type
YXR33, YXR3, YXR7
【YXR33】
It has excellent high toughness among matrix steel.
It is used in warm and hot forging dies, and is also called high toughness matrix steel.
【YXR3】
It is between YXR33 and YXR7 in toughness and abrasion resistance.
It is suitable for cold stamping dies and cold forging dies, but it can also be used for warm forging dies.
【YXR7】
it has a high carbon content and excellent abrasion resistance.
It is used for cold forging dies and cold pressing molds.
