Virat Special Steels is the biggest Supplier and Stockiest of AISI H11 Hot Work Steel.
AISI H11 is an all inclusive hot work tool steel with hot rigidity and durability. Good thermal conductivity and invulnerability to hot cracking and can be water cooled to a constrained degree.
Utilized for ejector pins, apparatus holders and shrink fit chucks.
Hot work tool steel with Chromium 5% has high strength and toughness, best thermal physical phenomenon and in susceptibility to hot cracking. This provides the essential necessities for long tool life in die-casting , Press Forging , extrusion processes etc.
