frequently asked questions
How do I choose a metal treatment process for custom parts?
The right metal treatment process depends on the part’s material, design, operating conditions, and performance requirements, such as strength, hardness, wear resistance, or corrosion resistance. Aalberts’ metallurgists and technical advisors can review your specifications and recommend the most suitable treatment for your custom parts.
What’s the best surface treatment for parts that see heavy friction?
Nitriding or ferritic nitrocarburizing may be suitable for metal parts exposed to heavy friction because these treatments can increase surface hardness and wear resistance. The best option depends on the part’s material, operating temperature, load, and lubrication.
Which metal treatment can improve the durability of my parts?
Nitriding and NitroSteel® can increase surface hardness, wear resistance, and corrosion resistance, while austempering, vacuum heat treatment, and steel or aluminum heat treating can improve strength and other material properties. The best treatment depends on the part’s material, design, and operating conditions.
What surface treatment is best for aluminum?
The best treatment for aluminum depends on the alloy and the required performance. Aluminum heat treating can improve strength, hardness, and dimensional stability, while other surface treatments may be needed for corrosion or wear resistance.
What heat treatment is best for hardening carbon steel?
Quench and temper is often used to harden carbon steel while providing strength and toughness throughout the part. Ferritic nitrocarburizing may be a better option when increased surface hardness, wear resistance, fatigue resistance, and corrosion resistance are priorities. The best process depends on the steel grade, part design, and performance requirements.
