We largest Supplier & Stockiest of H11 Hot Work Steel.
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.
Steel Properties
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.
