Overview
This source page is a mechanical bulk-ingest record for a PDF in the research-pulls corpus. It preserves source-level identity, routeable product/analyte scope, and exact extracted numeric lines for later human or fresh-context audit. It does not derive HMTc thresholds, percentiles, or brand-by-brand comparisons.
Key numbers
The worker extracted the full PDF text with layout preservation twice and compared extraction hashes before commit. The following lines are copied from numeric/table-bearing regions of the PDF and retain the source units and wording where legible:
- Received acid (1M, 3M, and 5M) was studied beside sodium chloride NaCl (1 wt%, 3.5 wt%, and 5 wt%). The potentiostat test
- pitting resistance equivalent number higher than (PREN = wt.%Cr+3.3 wt.%Mo+20 wt.%N) than 40. This has been made possible by high
- levels of chromium (25-27%), molybdenum (3-4.5%), and intermediate nitrogen mass fractions (0.25-0.28%). Super duplex stainless steels
- temperatures up to 650 C. These types also provide good ductility and toughness in this temperature range. Corrosion and oxidation resistance
- is provided primarily by a high chromium content, generally higher than 16 wt% (5). It is found that welding parameters (such as heat input)
- has been verified, and the results are shown in Table 1.

Methods (brief)
- suspensions (0.3 and 0.05 μm). Then the samples were cleaned with water and alcohol then dried by dry air. After polishing, the specimen shall
Implications
This page makes the source discoverable for category-level evidence routing. Values remain source-native and should be used only with the stated matrix, species, basis, geography, and censoring context from the paper. The page does not convert total mercury to methylmercury or use total arsenic as inorganic arsenic.

Verification notes
- Identity check: DOI, raw handle, candidate cite-key, and SHA-256 were compared against existing the linked reference record pages before creation.
- Full-PDF read:
pdftotext -layoutwas run on the full PDF twice; extracted text hashes matched before the page was written. - Numeric verification: numeric/table-bearing lines were selected mechanically from the verified extraction and preserved without unit conversion or rounding.
- Brand firewall: the worker skips PDFs when extracted numeric lines appear brand/manufacturer-sensitive; this page contains category-level or species-level evidence only.
- HMTc firewall: no threshold, percentile, pass/fail, clean/dirty, or certification math is stated.
