Corrosion Resistance and Cleanability

Choose tool steel grades containing sufficient chromium like 420, 416, and 440C balanced for hardness, corrosion protection, and cost.

Decorative Finishes

For polished gold, nickel, or chrome plating select readily polished tool steel grades like 416, 430, and 303 without surface defects.

Strength and Wear Resistance

Grades like A2, D2, and S7 provide an optimized combination of hardness, tensile strength, and fatigue resistance on friction surfaces like gears, bearings, and pivots.

Thermal Processing Suitability

For tool steel components requiring hardening or other heat treatment after fabrication choose grades like P20, H13, or 420 with known processing behaviors.

Matching each tool steel grade’s nuanced property capabilities to individual consumer product demands ensures ideal long-term functionality.

Tool Steel Manufacturing Advantages

In addition to outstanding in-service properties, tool steel offers manufacturing advantages that enable innovation:


Melting and casting tool steel allows consolidating complex consumer product components into durable one-piece castings reducing assemblies and fasteners.


The ability to precision machine, grind, turn, and drill tool steel facilitates component geometries with much tighter tolerances and better surface finish than castings or plastic parts.

Stamping and Forming

Tool steel’s formability when hot supports high-volume stamped, pressed, or forged consumer product parts with thinner walls and more intricate shapes than achievable with other metals.

Joining Flexibility

Tool steel allows joining options including welding, brazing, adhesive bonding, swaging, and sintering. This supports flexibility in consumer goods assembly techniques.

Finishing Options

Tool steel’s polishability facilitates decorative mechanical finishing or luxurious plated finishes. Smooth surface perfection showcases quality.

Capitalizing on these manufacturing advantages provides paths to reduce costs while innovating better consumer products.
