Vee Kay Steel Trader is the largest Supplier & Stockiest of H10 Steel.
H10 is an amazing high-temperature quality and treating resistance, thermal
conductivity and low powerlessness to hot cracking. May be water cooled to a
restricted degree. It’s suitable for cold hobbing.
Utilized for Press and penetrating mandrels pass on supplements, heavy metal
die casting tools.
Hot Work Steel
H10 is equivalent steel of DIN 2365 with good high-temperature toughness and
high tempering resistance, less Susceptibility to high hot cracking, good
thermal conductivity, Can be water-cooled to a limited extent.
