HOT WORK STEEL (H-13)

Wellington Hot Work Steel is best general purpose tol steel grade for Hot Work applications. Furnished with a "soft Anneal". Wellington Hot Work Steel is delivered at approximatley 207 BHN. This grade offers excellent "Red Hardness", i.e. retains hardness at elevated temperatures. Displays excellent shock resistance and abrasion resistance. Wellington Hot Work Steel can withstand drastic temperature changes while in service.

WELLINGTON HOT WORK STEEL
Heat is a formidable enemy of any alloy or tool steel. Alternating temperatures or severe temperature change in service are the worst. Wellington Hot Work Steel withstands "Thermal Shock" and retains toughness and wear resistance in the most severe of these circumstances.
