    API 20E Bolting

    Technically you can purchase from another vendor but it is a headache on the documentation end. We (Spring Bolt) are certified, but before we were most customers would not accept bolting that was not monogram. So we took the plunge, spend the money, and got our licenses (API Q1, 20E and now 20F)

    Continuous cast steel making process is prohibited- API 20E

    API 20E BSL-3 states you can not use continuous cast steel. Looking at my historical 4140 MTRs all of it was made by means of continuous cast. I do not know my other options, or where to get material casted by other means. Any suggestions?

    API 6A Fasteners?

    Many companies are asking me to now quote ASTM A193, A194, A320, etc. to API 6A. I have tried reading through API 6A, and I am not seeing any modification to the ASTM specs. To me the the fastener specializations are called out in API 6A as a reference (when to use which bolt). Does that make...

    "Ductility Test"

    Does anyone have any information on a ductility test. All I know is they mentioned 12%x4D. It sounds like they are talking about testing the elongation, but I am not sure. Thanks for the help!
