    Vacuum Heat Treating 316L & 2205 Parts

    Hi Stainless Steel Experts, Is it possible to vacuum anneal (bright anneal) 316L and duplex 2205 parts at the same time? The annealing temps are almost the same (1900F/1040C) for both alloys and parts' thickness is less than 0.6 inches. I know 316L parts can be bright annealed with no major...

    Sour Water Injection Line?

    We are considering duplex 2205 or super duplex for some parts of this line. I know MR0175 is not a guideline for corrosion control or other type of corrosion like pitting. I was following it for partial pressure calculations. I wasn't aware the 0.05 psi H2S limit only applies to carbon steels...

    Sour Water Injection Line?

    Hi Steve, Thanks for all your helpful tips and hints. This is very useful information. I am following MR0175/ISO15156 and according to the standard you just need as little as 0.05 psi partial pressure to be considered sour. I also noted that ISO 15156-3 has more information regarding 316L...

    US Equivalent to EN 10210-S355 J2H grade Seamless Tube

    Hi, Hope someone can help me with this query. I need to find a en equivalent US grade to EN 10210-S355 J2H (1.0576), which is a structural non alloy steel good for relatively cold temperatures. I need seamless tubes not pipes. It is the low temperature application and sizes what is making it...
