Product Description

Free Cutting Hot Work Steel SKT4 1.2713 Compacting Mold Tool Square Steel 

1: AISI L6 steel introduction
AISI L6 is  defined as Cr-Ni-Mo alloyed hot work tool steel as per ASTM A681.it is equivalent with Germany grade 1.2714/55NiCrMoV7.AISI L6 has good resistance to thermal shock and heat cracking,good mechanical characteristics and toughness in hot and cold conditions,good resistance to the tempering.It is normally supply in hardened, quenched & tempered condition, and also in annealed condition in special case.AISI L6 Steel can maintain hardness above 60 HRC for sections of 75 mm (3 in.) thickness.
