Heat Treating Stampings & Fineblankings

Metal stamping and fineblanking are forming methods used to produce small, near-net-shape components that exhibit high strength.

Best Practices for Heat Treating Stampings & Fineblankings

Metal stamping converts sheet metal into shapes by exerting massive force with a stamping die. Fineblanking is a specialized metal stamping process that is used for parts that require characteristics such as flatness or a fully formed sheared edge.

High Volume, Quick Turnaround

Stampings and fineblankings are often produced in large quantities, and cost-effective processing is often a concern. Our continuous heat treatment furnaces efficiently process these small parts. When coupled with our scheduling philosophy that allows for rush or emergency work, we help keep your supply chain flowing.

Consistent Treatment

A common concern when processing parts using continuous equipment is preventing masking. Masking refers to parts nesting or overlapping during heat treatment, preventing the proper transformation of the part that is blocked from heat and atmosphere. We prevent masking and deliver consistent results from part to part and lot to lot using automated loading systems that prevent human error or furnace overloading.

Case Hardening

Carburizing is a case hardening method that is often specified for parts that are engaged in motion such as automotive seat recliners and parking brake ratchets. Carburizing creates a hard outer layer on the part while preserving a soft, ductile core which enhances the toughness of parts that encounter friction with mating components.

Through Hardening

This process provides consistent hardness throughout the entire part for components requiring high strength. Structural components, brackets, and automotive seating assembly components such as belt-buckle tongues are usually processed by through hardening.

Ferritic Nitrocarburizing

Ferritic nitrocarburizing (FNC), often used for automotive transmission components, is a specialized case hardening process that lends extra corrosion resistance to parts while preventing distortion during heat treatment.

Materials Used for Stampings & Fineblankings

Carbon steels and boron steels are the most common materials used for stampings and fineblankings. Parts typically begin as sheet metal that is then brought into shape by a series of die strikes.

Low-Carbon Steels

  • 1010, 1018, 1020, 8620, SCM415

Medium-Carbon Steels

  • 4130, 4140, 42CrMo4

Boron Steels

  • 10B21

Stainless Steels
