Laboratory

Lab TestingRolled Alloys offers global metallurgical assistance.  With full metallurgical labs, we offer alloy corrosion testing and high temperature oxidation studies.  After nearly 60 years of experience in the heat treat industry the metallurgists have performed dozens of long term high temperature oxidation studies.  With a global emphasis on corrosion resistant alloys and duplex stainless steels, we have performed various corrosion studies on iso-corrosion curves in acids, critical pitting, crevice corrosion and stress corrosion cracking tests.   Additional laboratory services include multiple optical microscopes and SEM equipment.  Rolled Alloys can help you find the best alloy suited for your application.  

Material AnalysisRolled Alloys employs a group of applications engineers who work directly with fabricators, engineering companies and end users to decide which material is best suited for each application.  Often times, this decision starts with a previously failed piece of equipment.  With polishing equipment, digital microscopes and full failure analysis reports, Rolled Alloys can assist you in determining modes of failure and even data on other alloy options to increase life expectancy and minimize costs.  Please contact a metallurgist if you need a full analysis.  Rolled Alloys has even done material testing and design to develop custom ZERON 100 (UNS S32760) forgings for subsea applications as well as corrosion and fatigue testing of high strength ZERON 100 (UNS S32760) slickline used in offshore oil and gas drilling.  

Material IdentificationA simple, yet important service that Rolled Alloys offers is positive material identification (PMI) using an Oxford Instruments XMET – 5000 handheld x-ray spectrometer.  Every Rolled Alloys stocking facility has a hand held analyzer to verify quality and accuracy of material shipped. We have also used these analyzers for identifying material that has been in service. This can help you confirm materials for reconstruction or even justifying alloy scrap credits.

Sample MaterialsLab test data cannot always simulate the actual environments in many applications.  Whenever possible, it is best to test various sample materials in a live process.  For this reason Rolled Alloys inventories free sample coupons for testing purposes.  Generally we inventory 4” x 4” coupons in a variety of thicknesses.  Some custom sizes are also available upon request.  In addition to application testing, these coupons along with sample MIG and TIG wire can be used for weld qualification testing.  Please contact a metallurgist for more information about obtaining a material sample.

Why? Why? Why? 316Ti – UNS S31635

There are occasional requests for 316Ti material. These requests are often on projects related to replacing or repairing older equipment.

Bar Product Terminology and Finish

The terminology used for bar products is occasionally misunderstood. General requirements, such as those for tolerances, marking, packaging, etc., are standardized in ASTM A484 for stainless bar products.

What are Stainless Steel Surcharges?

Metal surcharges have been applied in past years on several occasions, but the current run of surcharges on stainless steel began in 2001. This is the longest continuous run of surcharges and they will remain in place for the foreseeable future.
