Frequently Asked Metallurgical Questions
Our team of metallurgical experts can assist in identifying alternative alloys for high-temperature and corrosive applications. Regarding alternative materials for critical applications (Aerospace, Defense, etc.), it is best to contact the OEM in charge of specifying materials to minimize potential liability.

Rolled Alloys has a full-service metallography lab that focuses on performing root cause analyses and metallography testing for customers. This service is free of charge to our customers.
If you are wondering which alloy is best suited for your application, we recommend that you contact our Metallurgical Services Team. They can provide valuable assistance if you can provide them with details of your application, such as metal temperature and process environment makeup.

Martensitic stainless steels (410, 440C, 420, 416) and precipitation hardenable stainless steels (17-4, 15-5, 13-8, A-286) can be hardened by heat treatment. These are the only two classes of stainless steel that can be hardened by heat treatment. To understand heat treatment terminology better, please read our “Confused About Annealing and Heat Treating Terminology” blog.
The PREN is a calculated number based on an alloy’s chemical composition and is used to assess the resistance of stainless steels and nickel alloys to pitting corrosion, most typically chloride pitting. The higher the PREN, the better an alloy resists pitting corrosion. Alloys with higher PREN values are generally more suitable for aggressive environments. To read more about the PREN or to calculate the PREN of an alloy, please use our PREN Calculator.
MIG (Metal Inert Gas) welding, also known as GMAW (Gas Metal Arc Welding), is always done with spooled wire, usually 0.035″ or 0.045″, rarely 0.062″. TIG (Tungsten Inert Gas) welding, also known as GTAW (Gas Tungsten Arc Welding), is generally done with 36″ straight lengths of bare wire. Automatic TIG machines may use spooled wire, but 36″ lengths are only used for manual TIG. Electrodes are used for “stick welding”. They are typically 14″ lengths of wire, coated with a gray flux over all but the last 1-1/2 to 2″. Read More
