 * In order to ensure ASSAB618 hardenability performance, large-size steel added to the appropriate ratio of nickel. 
 ? 
 ASSAB618 vacuum degassing processing of chrome molybdenum alloy steel supplier of quenched and tempered condition, with about the advantages of: 
 □???? No risk of quenching crack 
 □???? Without heat treatment costs 
 □???? Save the time of heat treatment required 
 "???? Reduce mold production costs (without correction of deformation, only once polished) 
 □???? Mold easily amended 
 □???? Subjected to nitriding and flame hardened to increase the surface hardness and wear resistance of the mold. ? 
 ASSAB618 smelting of high quality standards, low sulfur content, has the following characteristics: 
 □???? Good polishing and photo-etching performance 
 □???? Good machining performance 
 □???? High purity and good homogeneity 
 □???? Uniform hardness distribution 
 ASSAB618 mold steel 100% ultrasonic flaw detection test.
