SA 240 310 and SA 240 310 H usage

SA 240 310 and SA 240 310 H usage

SA 240 310 and SA 240 310 H usage

(OP)
Hello,

I need an information about is using SA 240 310 suitable at 788 degree celsius or do we have use SA 240 310 H because of temperature?

Thanks in advance for your help.

RE: SA 240 310 and SA 240 310 H usage

Used for?

The problem with sloppy work is that the supply FAR EXCEEDS the demand

RE: SA 240 310 and SA 240 310 H usage

Your design code will most probably tell you this. Since you mentioned SA240, I assume your work is under one of the ASME BPV Sections, correct?
If true, have you looked up the applicable material notes (G, H, S, T and W) in section II-D?
Perhaps both 310 and 310H are possible, but one with restrictions, making it more appropriate to use the H-grade (thats what weve found over the years with similar materials).

If not, please tell us your applicable design code.

RE: SA 240 310 and SA 240 310 H usage

Section II-D can give some guidance in terms of allowables, but your very high operating temperature makes it a true high-temperature application, pointing to selecting H-grade material.

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
