6. FAQ: Technical Terms on Precision Casting, Materials & Installation

Frequently Asked Technical Questions

1. What is “investment casting” in precision casting processes?: It is synonymous with the lost-wax technique, where wax patterns create complex shells, resulting in superior accuracy, minimal subsequent machining, and fine surface texture for metal parts.
2. How does stainless steel 316 (CF8M) differ from 304 in joint performance?: SS316 contains molybdenum, granting markedly improved resistance to chlorides (pitting/crevice), making it ideal for harsh chemical, coastal, and food hygiene environments per ASTM A351/EN 10213.
3. What is ANSI/ASME B16.3 standard?: It is a U.S. standard that defines the dimension, pressure rating, and thread types of malleable iron and steel pipe fittings—including four-way joints—ensuring global interchangeability.
4. Can four-way joints be customized for odd sizes/materials?: Yes. Precision casting foundry facilities accept CAD or sample customization for materials such as duplex, super austenitic alloys, or sizes DN8–DN100+.
5. What quality inspections verify casting integrity?: Mandatory 100% visual check, hydrostatic (pressure) testing, and, for critical contracts, x-ray for porosity/defect analysis, strict adherence to ISO9001/204 and EN10204 standards.
6. How is corrosion tested for stainless castings?: Standardized by ASTM G48 (pitting) and ASTM A262 (intergranular corrosion); test coupons immersed in aggressive solutions quantify resistance, confirming suitability for the end-use environment.
7. What is the typical lead time for wholesale precision casting orders?: Sample: 14–21 days. Bulk production: 30–45 days post-confirmation; expedited under urgent project requirements.
