Issues regarding SH/T3406 flanges and fasteners
Thread Content
There is a project currently in progress that uses SH/T 3406 PN50 WN/RF flanges made of 304 stainless steel. Would it be acceptable to use 35CrMo for both the studs and nuts as well? I checked SH/T 3404, and it specifies that the material for studs and nuts should be 35CrMoA. Since our company’s inventory only includes fasteners made of 35CrMo, not 35CrMoA, I was wondering if it’s okay to use 35CrMo in this case?
What are the design temperature and operating temperature?
What are the design temperature and operating temperature?
Actually, the two are the same thing. For 35CrMoA, the relevant standards specify that “A” denotes “high quality”. However, in many standard specifications, this grade of material, 35CrMoA, does not exist at all.
What are the design temperature and operating temperature?
Hello, operating temperature: -15 to 250 degrees, design temperature: 280 degrees
