Requirements for non-metallic inclusions in materials for pressure vessels
Thread Content
The requirements for non-metallic inclusions in materials used for pressure vessels: The standards for forgings used in pressure vessels contain additional requirements regarding non-metallic inclusions in such materials in their appendices. Under what circumstances should this request be made, and what should be a reasonable level for it?
I’m facing this problem now too; I hope someone experienced can help answer it
Non-metals refer to harmful elements such as C, S, H, Si, P
