Hi-Hard Corporation provides several types of through hardened parts for various hot and cold processing operations. These rolls are made using 400 series stainless, medium/high carbon alloy steels, and tool steel. Hardness on these product will vary on appication and our controlled through the heat treatment. The hardness on these rolls is through the thickness of the material. Rolls are manufactured as solid and fabricated designs. To learn more on the through hardened rollers, high temperature alloy steel quench and tempered rolls, and tool steel rolls please persue information below or contact us for details.

Through Hardened Roller Capabilities

General Capabilities

THROUGH HARDENED PRODUCTS

THROUGH HARDENED STAINLESS STEEL
The Hi-Hard through hardened product is manufactured using modified 400 series stainless steel. The material is heated to austenitizing temperature, air quenched, and tempered to desired hardness level (up to 60 HSD). This material is used in elevated temperature applications where the roll is exposed to severe temperature changes, war conditions, corrosion, and impact.

Materials Used

400 Series Stainless

Heat Treatment

Quench and tempered: 40/50 HSD ; 50/60 HSD - Material is harden through entire wall

Roll sizes

Diameter: Up to 20"
Length: Up to 175"

Roll types (Normally in Hot Strip Applications)

Table Rolls
Looper Roll
Damming Rolls
Scale Breaker Rolls

HI TEMPERATRURE ALLOY QUENCH AND TEMPERED ROLLS

Rolls manufactured from this HI-TEMP ALLOY material can be made in solid or fabrications. These rolls typically have hardness levels up to 430 BHN and are used in applications where roll is subject to high temperature material processing and an elevated temperature environment. These material offer strength, toughness, abrasion resistance, corrosion resistance, and temperature cycling properties.

Materials Used

Nickel, Chrome, Molybdenum Alloy

Heat Treatment

Quench and tempered: 33-37 Rc / 38-42 Rc / 43-46 Rc

Roll sizes

Diameter: Up to 20"
Length: Up to 175"

Roll types

Caster Rolls
Scale Breaker Rolls
Pinch Rolls

QUENCH AND TEMPERED ROLLS

Rolls manufactured for quench and tempered materials can be made as solid for fabrications. These rolls typically have hardness up to 321 BHN and offer high core mechanical properties. These products are used where hi strength, toughness, and durability are of concern and wear is not a major issue.

Materials Used

4140, 4340, 1045
alloy steel

Heat Treatment

Quench and tempered: to 321 BHN

Roll sizes

Diameter: Up to 20"
Length: Up to 175"

Roll types
