SCM440 are of high-speed steel or ordinary steel SUJ2 same right? suj2 are of tool steel, his temper is obvious, SUJ2 die steel is generally divided into [] cold die steel, hot work die steel [] and [] This plastic mold steel types.

SUJ2 and is used in which the metal forging, casting, etc. \ stamping, cutting type. Due to the use of different kinds of mold, working conditions are very complex, so the mold steel, mold manufacturing according to their working conditions, should have high strength, wear resistance SKH-51,, hardness, M2 high speed steel, SKH-9, SKH51 sufficient toughness, hardenability and high hardenability, and other process performance.

This SUJ2 steel up to a maximum number of real purchase of the mold factory, but provides for high speed steel, and high speed for the main product is the main object SCM440.

We are now on the steel for SCM440 SCM440 SCM440 steel imports have also imported steel SCM440, steel was also called him: SCM440 alloy steel SCM440 SCM440 round rod! So, we are in fact the most accurate name SCM440 alloy structural steel this is most true, most people also understand.
