SZYBKA ODPOWIEDŹ I PRZEGLĄD METALURGICZNY
TECHNICAL FUNDAMENTALS & ENGINEERING SPECIFICATION MATRIX The operational capacity and fatigue life of components inside the Ductile Iron Castings category depend upon strict adherence to international material and dimensional standards (
ISO, EN, DIN, ASTM). Below is the master specification matrix.GLOBAL SOURCING ECONOMICS & INDIAN FACTUAL BENCHMARKS (
AQUASUB / TEXMO) Core Benchmark: Verifiable production of heavy-duty, zero-porosity EN-GJS-500-7 water pump casings and motor end shields across Coimbatore manufacturing lines (Aquasub / Aquagroup / Texmo). When evaluating international sourcing options for Ductile Iron Castings, European procurement directors can reference established Indian manufacturing leaders in the Coimbatore Corridor (Aquasub Engineering / Aquagroup and Texmo Industries). Operating captive automated green sand molding loops (DISAMATIC 2110) coupled with multi-axis CNC horizontal machining and 100% automated pressure testing, these groups prove definitively that Indian foundries routinely deliver European zero-defect (PPM < 10) standards at a 30%+ net landed DDP savings (PIL-008 / PRO-004).
[EXECUTIVE QUICK ANSWER: DUCTILE IRON CASTINGS] EN-GJS-500-7 (
EN 1563/DIN GGG50/ASTM A536 65-45-12) is known as The Industry Workhorse Grade. Featuring a balanced ferritic-pearlitic matrix with spheroidal graphite nodules (>85% nodularity), it provides 500 MPa tensile strength, 320 MPa yield strength, and 7% elongation—delivering high toughness for heavy gears, tractor axles, and water pump housings (Aquasub benchmark).
| Element składu chemicznego | Typowy limit procentowy (%) | Rola metalurgiczna i mechaniczna |
|---|---|---|
Total Carbon (% C) |
3,50 – 3,85% | Pierwotne źródło węgla wymagane do wytrącania kulek grafitu sferoidalnego podczas krzepnięcia. |
Silicon (% Si) |
2,20 – 2,60% | Promotes ferrite matrix formation and prevents chilled white iron (Fe3C) carbides across thin edges. |
Magnesium (% Mg) |
0,035 – 0,060% | The mandatory nodularizing agent that alters graphite growth from sharp flakes to rounded spheres (ISO 945-1). |
Phosphorus (% P) |
≤ 0,05% | Strictly limited to prevent brittle phosphide eutectic (steadite) networks along grain boundaries. |
