316/316L Dual Certifications - Metal and Metallurgy

Jul 10, 2006 · Dual certs simply mean that the material meets both the low carbon content of the L grade and the tensile/yield strength of the plain grade. What this means is that the high strength/yield of a particular dual certified material sample is not simply due to excess carbon content, but is a result of better alloying/quality control in the manufacture of the stainless steel. 316/316L Dual Certifications - Metal and Metallurgy Jul 10, 2006 · Dual certs simply mean that the material meets both the low carbon content of the L grade and the tensile/yield strength of the plain grade.

Use of Dual Certified Materials - ASME (mechanical) Code

Mar 14, 2003 · It is possible to create a metal that meets both the requirements for two different grades of material. For the 316/316L example, odering a dual certified grade gives you the low carbon content of the 316L material, for increased weldability, while still allowing you to use the higher allowable stresses of 316 that are given in the code (eg. Valve Material 316 316L CF8M CF3M Ball Check Gate Globe These grades offer tensile, creep and stress-rupture strength in higher-temperature applications. 316 and 316L offer better resistance to atmospheric and mild environments than 304 and 304L. Design Features 316/316L. 316 is resistant to dilute solutions (1-5%) of sulfuric acid to 49ºC (120ºF), except in some oxidising acids, where 316 is less

What is alloy sensitization? - Rolled Alloys, Inc.

Luckily many stainless steels are dual certified as 304/304L or 316/316L showing that they meet the low carbon limits of chemistry and the high strength of the straight grade. In addition to meeting the strength and chemistry requirements it is also common to see an intergranular corrosion test, such as ASTM A262 Practice E on the material test Why? Why? Why? 316Ti UNS S31635 - Rolled Alloys, Inc.In all three Euronorms, the Rp0.2 (YS) is listed as minimum 220 MPa (32 KSI) for plate. In ASTM standards there is a slightly lower YS for 316L (25 KSI) versus 316 and 316Ti (30 KSI), but since nearly all 316L is dual certified as 316, there is no practical difference.
